Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: endopeptidase activity.
It is reported to be involved in the biological process: proteolysis; ubiquitin-dependent protein catabolic process.
15 alleles are reported.
The phenotypes of these alleles are annotated with 24 unique terms, many of which group under: organ system subdivision; adult segment; organ system; sensillum; eo support cell; external compound sense organ; peripheral nervous system; eo sensory structure; imaginal precursor; abdominal sternite 5.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Proteasome B-type subunit; Proteasome, beta-type subunit, conserved site; Proteasome, subunit alpha/beta.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderately high expression.
Peak expression observed within 00-06 hour embryonic stages, at stages throughout the larval period, at stages throughout the pupal period, in stages of adults of both sexes.
