Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: serine-type endopeptidase inhibitor activity.
The biological processes in which it is involved are not known.
5 alleles are reported.
No phenotypic data is available.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Protease inhibitor I4, serpin; Protease inhibitor I4, serpin, conserved site; Serpin domain.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of extremely low expression.
Peak expression observed within 18-24 hour embryonic stages, during early larval stages, during late pupal stages, in adult male stages.
