Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: protein binding; sequence-specific DNA binding; DNA binding.
There is experimental evidence for 14 unique biological process terms, many of which group under: anatomical structure development; sensory organ development; cellular process involved in reproduction; cellular component organization or biogenesis; cell cycle; multicellular organismal reproductive process; growth; organ morphogenesis; immune response; wound healing; biological regulation.
46 alleles are reported.
The phenotypes of these alleles are annotated with 37 unique terms, many of which group under: organ system subdivision; adult segment; organ system; adult mesothoracic segment; external compound sense organ; synapse; axon; non-connected developing system; imaginal precursor; nervous system.
It has 4 annotated transcripts and 4 annotated polypeptides.
Protein features are: Basic-leucine zipper (bZIP) transcription factor; Fos transforming protein; bZIP transcription factor, bZIP-1.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of low expression.
Peak expression observed within 12-24 hour embryonic stages, at stages throughout the larval period, at stages throughout the pupal period, in stages of adults of both sexes.
