Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
It is reported to have molecular function: aminopeptidase activity.
An electronic pipeline based on InterPro domains suggests that it is involved in the biological process: proteolysis.
17 alleles are reported.
The phenotypes of these alleles are annotated with: eye; anterior crossvein; wing; ommatidium; wing hair; metatarsus.
It has 7 annotated transcripts and 7 annotated polypeptides.
Protein features are: Peptidase M1, alanine aminopeptidase/leukotriene A4 hydrolase; Peptidase M1, membrane alanine aminopeptidase, N-terminal; Peptidase M1, puromycin-sensitive aminopeptidase.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderate expression.
Peak expression observed during early pupal stages.
