Gene Snapshot
abrupt (ab) encodes a transcription factor that negatively regulates ecdysone signaling, as it binds to the product of tai. It regulates animal survival, organogenesis and multiple tissue morphogenesis, epithelial cell fate, cellular sexual identity, neuron differentiation and neuronal identity switch, cell migration, oncogenesis and germline differentiation. In many cell types, the product of ab is post-transcriptionally repressed by the steroid-induced miRNA let-7. [Date last reviewed: 2019-03-07]

C2H2 ZINC FINGER TRANSCRIPTION FACTORS -
Zinc finger C2H2 transcription factors are sequence-specific DNA binding proteins that regulate transcription. They possess DNA-binding domains that are formed from repeated Cys2His2 zinc finger motifs. (Adapted from PMID:1835093, FBrf0220103 and FBrf0155739).
Protein Function (UniProtKB)
Expression is vital for development; may be involved in transcriptional regulation. In embryos, muscle specific expression is required for segmental nerve b (SNb) motoneuron target recognition within ventral longitudinal muscles. Has a role in establishing and maintaining embryonic muscle attachments, adult sensory cell formation (macrochaetae) and morphogenesis of adult appendages (legs, antenna aristae and male external genitalia). Has a role in the morphogenesis of the class I dendritic neurons: selective expression of ab in class I da neurons plays a pivotal role in forming dendritic arbors, which are characteristic of the class I cells. The development of more complex arbors of class II-IV neurons depends on the absence of ab.

Phenotypic Description (Red Book; Lindsley and Zimm 1992)
ab: abrupt
thumb
ab: abrupt
Edith M. Wallace, unpublished.
Vein L5 usually stops after posterior crossvein. Scutellar bristles usually fewer. Wing effect probably acts during contraction period (Waddington). Overlaps wild type. Expression more severe in females than in males and when pupal stage takes place at 20 than at 25. TSP during the first 10% of pupal stage. (Thompson, Bruni, Carbonaro, and Russo, 1988, DIS 67: 86). RK2.
ab2
Vein L5 does not reach margin. Scutellar bristles always fewer than wild type. Hairs parted down midline of thorax and abdomen. Supra-alar bristles sometimes absent. Coxae tend to be thickened. Males sterile and have rotated genitalia. ab/ab2 resembles ab/ab but has a stronger bristle effect. RK2.

Epidermal expression begins in stage 11 in a pattern of stripes and is uniform by stage 12. ab is expressed in all 30 embryonic abdominal muscles with the highest concentrations in the ventral longitudinal, ventral oblique, and segmental border muscles. ab is also expressed in all imaginal discs.

Additional Descriptive Data

ab is widely expressed in somatic and germline cells during oogenesis. During stage S9, the accumulation of protein in the nucleus decreases specifically in border cells. The ab antibody also stains the apical surfaces of follicle cells, the oocyte cortex, and ring canals.

(Jang et al., 2009)

ab is expressed in all the cells of the ventral midline starting in stage 9. The only other site of nervous system expression is the stomatogastric nervous system and its precursors. Epidermal expression begins in stage 11 in a pattern of stripes and is uniform by stage 12. ab is expressed in all 30 embryonic abdominal muscles with the highest concentrations in the ventral longitudinal, ventral oblique, and segmental border muscles. ab is also expressed in all imaginal discs.

    Other Comments

    ab is a repressor of ecdysone signalling and border follicle cell migration.

    (Jang et al., 2009)

    dsRNA has been made from templates generated with primers directed against this gene. ab RNAi causes an increase in dendrite arborization of ddaD and ddaE neurons. There is an increase in the number and length of lateral branches, which results in an expansion of the coverage field, most noticeably along the anteroposterior (AP) axis. In addition to these defects,ab RNAi also causes frequent cell death, defects in muscle, alterations in the number of MD neurons, defects in dendrite morphogenesis and reproducible defects in da dendrite development.

    (Parrish et al., 2006)

    New annotation (CG32830) in release 3 of the genome annotation.

    (FlyBase Genome Annotators, 2002-2003)

    P-element excision and γ ray induced lethal mutations of the enhancer trap BL97 fail to complement ab.

    (Hu et al., 1995)

    ab encodes a BTB-zinc finger regulatory protein that controls the specificity of neuromuscular connections.

    (Hu et al., 1995)

    Loss of vein mutations cause suppression of rhohs.PSt ectopic vein phenotype and enhancement of the rhove-1 loss of vein phenotype.

    (Sturtevant and Bier, 1995)

    Identification: Mutations affecting neuromuscular connectivity, using an antibody to Fas2.

    (van Vactor et al., 1993)

    Mutations in ab affect individual longitudinal veins: vein specific effects.

    (Diaz-Benjumea and Garcia-Bellido, 1990)

    kni, tg, tt, ab, cv, cv-2, cv-c and cv-d belong to the radius incompletus phenotypic group within the 'lack-of-vein' mutant class. Loss-of-function alleles at these loci remove stretches of veins in two or more longitudinal veins. Double mutants of this group have additive phenotypes suggesting the genes are vein-specific, and small lanceolate wings. Therefore involved in whole vein-region specification rather than vein differentiation. ab alleles may have pleiotropic effects on leg development or be embryonic lethal.

    (Diaz-Benjumea et al., 1989)

    Loss of function is lethal, with effects on connectivity of segmental nerves; hypomorphic alleles affect the development of wing veins, especially wing vein L5, with effects in coxa, male genitalia and bristles.
