RUNT DOMAIN TRANSCRIPTION FACTORS -: Runt-domain (RD) transcription factors are sequence-specific DNA binding proteins that regulate transcription. These proteins are characterized by a Runt domain of 128 amino acids that mediates DNA binding and heterodimerization with a non-DNA binding β-subunit to form the Core Binding Factor transcription factor complex. (Adapted from FBrf0206845 and FBrf0138356).

Protein Function (UniProtKB)

Involved in prepatterning photoreceptor precursors in the developing eye; in the larval eye disk it defines a subset of cells as an equipotential group that is competent to respond to the sevenless developmental signal and another subset that confer proper photoreceptor identity by positively regulating the homeo box gene Bar. Involved in the aop/pnt dynamic in a Ras-dependent manner to regulate pros expression. Promotes apoptosis in the pupal eye by directly activating aos and klu. Also modulates hid- and rpr-mediated cell death. Regulates amos function in olfactory sensilla development.

Phenotypic Description (Red Book; Lindsley and Zimm 1992)

lz: lozenge

Many alleles with a wide range of phenotypes. Homozygous males have eyes size variably reduced and often ovoid in shape. Surface with fused facets producing a roughened glistening appearance (= glossy), or smooth with pigment either uniformly distributed or concentrated at periphery of the eye (= spectacle). Eye pigment variably reduced, and Malpighian tubes slightly lighter than normal (Brehme and Demerec, 1942, Growth 6: 351-56). Tarsal claws reduced to different extents by different alleles. Spermathecae and parovaria (= accessory glands) often missing in homozygotes with abnormal parovaria seen in some heterozygous females (Anderson, 1945). Females often sterile, but sterility appears to be primarily an ovarian defect, since some genotypes which lack parovaria and spermathecae are female fertile. Some alleles lack the class of hemocytes called crystal cells, or at least lack the crystalline inclusions of those cells; the inclusions can be shown to comprise prophenoloxidase, and flies lacking crystal cells are deficient in phenol oxidase activity and suppress the phenotype of Bc. Five of fifteen alleles tested (lz36f17, lz46, lzD, lzrfg, and lzs) suppress Bc and lack crystal cells and phenol oxidase activity (Rizki and Rizki, 1981, Genetics 97: s90); postulated that lz+ crucial to differentiation of crystal cells, and is not a structural gene for any of the five phenol oxidase moieties. Peeples, Geisler, Whitcraft, and Oliver report defective phenol oxidase activity in lzg (1969, Biochem. Genet. 3: 563-69) lz64j, lz66c, lzs, and lzy4, but not in lz50e, or lzK (1969, Genetics 62: 161-70); Warner, Grell, and Jacobson (1974, Biochem. Genet. 11: 359-65) found no phenol oxidase activity in lzrfg, but normal levels in lz1 and lzg.

lz1

Eye narrower than wild type and ovoid. Irregular facets in some areas cause rough patches; areas of fused facets appear as smooth patches. Eye color appears normal but, in combination with st, slight reduction in red pigment detectable. Tarsal claws reduced. Developmental study by Waddington and Pilkington (1942, DIS 16: 70) shows failure of middle cell layer of optic disk to penetrate between cells of outer layer; surface thus covered with primary pigment cells. Females sterile. Parovaria and spermathecae absent; some lz/+ females have abnormal parovaria (Anderson, 1945, Genetics 30: 280-96). Suppressed by su(f)6 (Schalet, 1970, Genen. Phaenen 14: 16-17), su(Hw)2, e(we)s, and su(pr)e3; enhanced by su(s)3 and su(wa) (Rutledge, Mortin, Schwarz, Thierry-Mieg, and Meselson, 1988, Genetics 119: 391-97). Phenol oxidase activity increased from 17% to 71% normal (Snyder and Smith, 1976, Biochem. Genet. 14: 611-17). RK1.

lz3

Eye size sharply reduced; surface smooth. Optic disk of mature larva and prepupa two-thirds normal size (Chen, 1929, J. Morphol. 47: 135-99). Red pigment greatly reduced; color yellowish brown, cream colored in combination with v. Tarsal claws vestigial. Homozygous females lack parovaria and spermathecae and are sterile; lz3/+ females lack parovaria and many have abnormal spermathecae [Anderson, 1945, Genetics 30: 280-96 (fig.)]. Unaffected by su(f)6 (Schalet, Snyder, and Smith, 1976, Biochem. Genet. 14: 611-17). RK1.

lz34

Eye phenotype intermediate between lz and lz3. Surface of eye has large areas of fused facets with a few normal facets (Clayton, 1957, Genetics 42: 28-41); eye color dark red with small yellowish spots. Larval Malpighian tubes slightly lighter than normal; variable (Brehme and Demerec, 1942, Growth 6: 351-56). Tarsal claws reduced. Spermathecae and parovaria absent from homozygous females, which accumulate stage 14 oocyte and are quite infertile; some lz34/+ females have abnormal parovaria (Anderson, 1945, Genetics 30: 280-96). Eye effect, but not other aspects of phenotype, enhanced by spae(lz); eye converted from a glossy to a spectacle phenotype (Beeson and Bender, 1975, J. Exp. Zool. 193: 177-90). In the presence of su(lz34), lz34 flies have virtually normal eyes. Beeson and Bender were unable to confirm previous observations of Bender and Green (1960, Genetics 45: 1563-66) that su(lz34) increases the fecundity of lz34 females. Unaffected by su(f)6 (Schalet) or su(Hw)2; however suppressed by su(pr) and enhanced by su(s) and su(wa) (Rutledge, Mortin, Schwarz, Thierry-Mieg, and Meselson, 1988, Genetics 119: 391-97). RK1.

*lz35

Eyes reduced and diamond shaped; color opaque brown. Homozygous females sterile. lz35/lz females fertile. RK1.

lz37

Eye size reduced. Areas of irregular facets in posterior region of eye; eye color normal. Enhanced by su(f)6 (Schalet, 1970, Genen. Phaenen 14: 16-17); also enhanced by su(Hw)2 and su(s) (Rutledge, Mortin, Schwarz, Thierry-Mieg, and Meselson, Genetics 119: 391-97). Phenol oxidase level decreased from 94% to 58% of normal (Snyder and Smith, 1976, Biochem. Genet. 14: 611-17). RK1.

lz48f

Unaffected by su(f)6 (Schalet).

*lz49h

Eye size sharply reduced; surface smooth; red pigment distributed over entire eye. Tarsal claws normal. Spermathecae and parovaria present and normal in females, which are fertile. Complements all lz alleles tested except lz50e.

lz50e

Like lz49h. Eyes reduced in size and almond shaped; no indication of facets; covered with indentations, giving a pock-marked appearance. Hairs on eye surface sparse or absent; eye surface glossy with many large black or brown flecks. Tarsal claws normal. Females fertile; spermathecae and parovaria present and normal. lz50e/lz has normal eyes except for a few flecks. Complements most other lz alleles except lz49h, lz52c, and those associated with rearrangements or deficiencies. Unaffected by su(f)6 (Schalet). RK1.

*lz52c

Eyes mottled, yellowish brown, darker at rim; facets fused. Males semisterile with missing tarsal claws, although pulvilli and endopodia normal. Third antennal segment slightly reduced. lz52c/lz50e females resemble lz50e. RK1.

*lz59

Eyes reduced in size and ovoid; facets fused; surface slightly rough and almost or completely hairless; color light brown with darker, slightly reddish rim; almost colorless in combination with v. Tarsal claws practicaly absent as in lzc1. Males sterile, (possibly associated with X-autosome translocation), transmit no motile sperm to females; therefore, homozygous females not observed. lz59/lz37 females intermediate between the two mutants in eye phenotype, have reduced tarsal claws, and are weakly fertile. RK2.

lz61f

Facets completely fused; eye color dark, but pigment unevenly distributed and concentrated at margin. Females found to be fertile by Burdicks, but were sterile when studied by Schwalm, Bender, and Klingle (1970, DIS 45: 91) who studied the ultrastructure of eggs produced by homozygous females. lz61f/lz females more nearly normal than either mutant; facets disrupted and fused only in posterior third of eye; also fertile. RK1.

lz63

Eye shape oval; color brown, darkest at margin; surface smooth and glossy. Viability and fertility of both sexes good. RK1.

lz63f

Eye size moderately reduced; surface smooth; color brownish with darker margin. Tarsal claws and pulvilli strongly reduced. Spermathecae and parovaria absent; female reproductive capability strongly reduced. lz63f complements lz50e but not lz34, lzD, or lz61f (Klingele). Spermathecal number of lz63f/lzK 0-3. RK1.

lz71a

Phenol oxidase activity severely reduced; further reduced in presence of su(f) (Snyder and Smith), 1976, Biochem. Genet. 14: 611-17.

*lzcl: lozenge-clawless

Eyes narrow and small without facets; surface has rough spots; color amber, both pteridines and ommochromes affected, darker at rim. Tarsal claws absent. Third antennal segment reduced; sensilla on antennae abnormal. Phenotype similar in both sexes. Females infertile and lack spermathecae and parovaria. Autonomous in transplants. RK1.

lzD: lozenge-Dominant

Males and homozygous females resemble lzs. Heterozygous females sometimes have roughened eyes. Apparent dominance shown by H. Bender to be caused by the presence of spae(lz); heterozygous expression additionally enhanced by presence of In(2LR)bwV1.

lzg: lozenge-glossy

Eyes smaller than wild type; surface glossy from fused facets; a few normal facets also present; color dark blood red, bright red in combination with st or v. Larval Malpighian tubes slightly lighter than normal (Brehme and Demerec, 1942, Growth 6: 351-56). Tarsal claws reduced. Spermathecae and parovaria absent from homozygous females, which have reduced fertility; lzg/+ females tend to have abnormal parovaria [Anderson, 1945, Genetics 30: 280-96 (fig.)]. RK1.

*lzgl: lozenge-glued

Eyes of male reduced and roughened like Gl; color dark; female eyes somewhat less extreme. lzgl/lz intermediate between lzg1 and lz and sterile. Homozygous females fertile. RK1.

lzK: lozenge of Krivshenko

Eyes narrow and moderately rough; facets irregular; eyes of homozygous females more nearly normal than those of males. Tarsal claws normal. Females fertile; spermathecae and parovaria present. Interactions of lzK with other lz alleles described by Green [1961, Genetics 46: 1169-76 (fig.)]. Unaffected by su(f)6 or su(Hw)2; however suppressed by su(pr) and enhanced by su(s) and su(wa) (Rutledge, Mortin, Schwarz, Thierry-Mieg, and Meselson, 1988, Genetics 119: 391-97). RK1.

*lzM58: lozenge of Meyer

Eyes small and oval; surface glossy; color brownish. Tarsal claws missing. Homozygous females moderately fertile, although spermathecae absent; lzM58/lzs also fertile. RK1.

lzs: lozenge-spectacled

Eye size reduced, narrower than normal; no true facets; whole eye has glossy surface; color yellow-brown with darker rim, creamy in combination with v. Tarsal claws vestigial. Homozygous females lack spermathecae and parovaria and are sterile. lzs/+ females tend to have abnormal parovaria (Anderson, 1945, Genetics 30: 280-96). RK1.

lzy4: lozenge in yellow-4

Similar to lzs but eye color redder. Homozygous females lack spermathecae and parovaria and are sterile; lzy4/+ females have abnormal parovaria and tend to lack spermathecae and parovaria (Anderson, 1945, Genetics 30: 280-96). RK1.

Summary (Interactive Fly)

transcription factor - AML-1 homolog - involved in sensillogenesis in antenna - mutants lack basiconic sensilla and some trichoid sensilla - the presence of Lz in R3/4 precluster cells is sufficient to endow them with a second wave cell fate response repertoire

lz protein can act as a transcriptional repressor of dpn in the presence of ct protein, with which it directly interacts.

(Canon and Banerjee, 2003)

lz is required during stages 10 to 14 of embryogenesis for crystal cell development, and later during larval stages to replenish lost crystal cells.

(Lebestky et al., 2000)

lz acts in a dose-dependent manner to specify the fate of the sensilla trichoidea and sensilla basiconica in the antenna.

(Gupta et al., 1998)

lz participates in the regulatory hierarchy of eye development by specifying cell fates for several cell types, promoting non-neuronal cell fates of cone and pigment cells over the neuronal fates. Developmental basis of the lz eye phenotype can be attributed to changes in cell identity and recruitment.

(Crew et al., 1997)

Lack of lz function causes a change in cone cell fate inducing them to take on a neuronal identity.

(Daga et al., 1996)

lz functions as a negative regulator of svp in R7 and cone cell precursors. lz controls svp and B expression in the developing eye disc, helping to define the fate of cells that arise from the second wave of mitotic division (R1/R6, R7 and cone cells).

(Daga et al., 1996)

lz may play a permissive role in allowing the non-neuronal support cells (cone or pigment cells) to choose their fate.

(Crew et al., 1995)

Mutation analysis of lz³ suggests that lz activity may be required for founder cell specification.

(Ray and Rodrigues, 1995)

Additional alleles of lz have been isolated in screen for lethal mutations that fail to complement Df(1)10-70d.

(Santamaria and Randsholt, 1995)

Mutations in lz cause a pleiotropic range of phenotypes including severe morphological defects in the compound eye. These defects are associated with altered patterns of cell birth and cell death occurring during critical periods of cell-cell interactions with recruitment.

(Crew et al., 1993)

Alleles show a wide range of phenotypes. Eyes variably reduced in size and often ovoid in shape. Surface with fused facets producing a roughened glistening appearance (= glossy), or smooth with pigment either uniformly distributed or concentrated at periphery of the eye (= spectacle). Tarsal claws reduced to different extents by different alleles. Females often sterile, but sterility appears to be primarily an ovarian defect, since some genotypes which lack parovaria and spermathecae are female fertile. Some alleles lack the class of hemocytes called crystal cells, or at least lack the crystalline inclusions of those cells; the inclusions can be shown to comprise prophenoloxidase and flies lacking crystal cells are deficient in phenol oxidase activity and suppress the phenotype of Bc. Double mutants produced by recombination all have the extreme phenotype of lz^s.

(Lindsley and Zimm, 1992)

It has been postulated that lz⁺ crucial to differentiation of crystal cells and is not a structural gene for any of the five phenol oxidase moieties.

(Lindsley and Zimm, 1992)

Behavioural data suggests antennal and maxillary basiconic sensilla may be important receptors for short chain alcohols and organic acids but less crucial for acetates, aldehydes and ketones.

(Venard and Stocker, 1991)

The lz mutant phenotype and the loss of maxillary basiconic sensilla have only subtle effects on the behaviours induced by esters and carbonyl compounds.

(Venard and Stocker, 1991)

Mutants in lz cause the loss of prophenoloxidase activity. Encapsulation of eggs from the parasitoid strain L.boulardi demonstrate that phenoloxidases are required only for blackening and hardening of haemolytic capsules.

(Rizki and Rizki, 1990)

Mating studies of lz mutants suggests that antennal basiconic sensilla are important for neither the perception of the attraction pheromones of virgin females nor the inhibitory pheromone of mated females.

(Stocker and Gendre, 1989)

Five out of 15 alleles of lz suppress the Bc¹ phenotype.

(Rizki and Rizki, 1981)

The lz locus is active during the first half of the egg stage.

(Rizki and Rizki, 1981)

No phenol oxidase activity in lz^rfg, but normal levels in lz¹ and lz^g.

(Warner et al., 1974)

Defective phenol oxidase activity in lz^g.

(Peeples et al., 1969)

Defective phenol oxidase activity in lz^64j, lz^66c, lz^s and lz^y4, but not in lz^50e, or lz^K.

(Peeples et al., 1969)

Spermathecae and parovaria (= accessory glands) often missing in homozygotes with abnormal parovaria seen in some heterozygous females.

(Anderson, 1945)

Eye pigment variably reduced and Malpighian tubes slightly lighter than normal.

(Brehme and Demerec, 1942)
