Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Its molecular function is unknown.
There is experimental evidence that it is involved in the biological process: stomatogastric nervous system development; determination of genital disc primordium; protein targeting to Golgi; compound eye retinal cell programmed cell death; regulation of epidermal growth factor receptor signaling pathway; ommatidial rotation; epidermal growth factor receptor ligand maturation; imaginal disc-derived wing morphogenesis; behavioral response to ethanol.
152 alleles are reported.
The phenotypes of these alleles are annotated with 60 unique terms, many of which group under: organ system subdivision; adult segment; nervous system; external compound sense organ; embryonic/larval neuron; peripheral nervous system; adult mesothoracic segment; female germline cyst; commissure; multi-cell-component structure.
It has 2 annotated transcripts and 2 annotated polypeptides.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of low expression.
Peak expression observed within 00-12 hour embryonic stages.
