Gene Snapshot

cryptocephal (crc) encodes a protein that belongs to a member of the CREB/ATF family of basic-leucine zipper transcription factors. It serves as an coactivator of the product EcR of to promote expression the molting peptide hormone encoded by ETH. It also acts as an unfolded protein response transcription factor to regulate glycolytic genes in response to ER stress. [Date last reviewed: 2019-03-07]

Summaries

Gene Group (FlyBase)

BASIC LEUCINE ZIPPER TRANSCRIPTION FACTORS -: The basic leucine zipper (bZIP) transcription factors are sequence-specific DNA-binding proteins that regulate transcription. They are characterized by a 60-80 amino acid bZIP domain: a basic DNA binding domain followed by a leucine zipper dimerization domain. (Adapted from FBrf0152056).

Phenotypic Description (Red Book; Lindsley and Zimm 1992)

crc: cryptocephal

Homozygotes frequently die as larvae; failure to eliminate chitinous mouthparts at the larval molt frequently results in larvae with suspernumerary mouth parts; homozygotes undergo pupation but rarely eclose from puparia. Imaginal head is not everted from thorax. Except for slightly reduced eyes and shortened legs, wings, and thoracic bristles, the head and thorax are fully differentiated; frequently fail to pass gas bubble to anterior retro-opercular position, thus failing to provide space for head eversion. Head eversion is inhibited by integument being more rigid than normal. Mutant integument contains more glucosamine than normal; Sparrow and Chaddfield unable to confirm (1982, Dev. Genet. 3: 235-45). Feeding glucosamine to wild-type larvae produces a phenocopy very similar to l(2)crc. Abdomen often shows no differentiation, and internal organ development is arrested at pupal stage. Lethality suppressed by su(crc)1 (Sparrow, 1981, Genet. Res. 38: 297-314). RK3.
