Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
An electronic pipeline based on InterPro domains suggests that it has the molecular function: serine-type endopeptidase activity; chaperone binding.
There is experimental evidence that it is involved in the biological process: protein lipidation; lateral inhibition.
17 alleles are reported.
The phenotypes of these alleles are annotated with: Z disc; mesothoracic tergum; mouth hooks.
It has 5 annotated transcripts and 5 annotated polypeptides.
Protein features are: Apoptosis regulator, Bcl-2 protein, BAG; Peptidase S1/S6, chymotrypsin/Hap; Peptidase S1/S6, chymotrypsin/Hap, active site; Peptidase S1A, chymotrypsin-type; Peptidase cysteine/serine, trypsin-like.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of very low expression.
Peak expression observed within 18-24 hour embryonic stages, at stages throughout the pupal period.
