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.
There is experimental evidence that it is involved in the biological process: response to DNA damage stimulus.
15 alleles are reported.
The phenotypes of these alleles are annotated with: eye; trichogen cell; macrochaeta; microchaeta; ommatidium; eo neuron.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Peptidase T1A, proteasome beta-subunit; 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 00-12 hour embryonic stages, at stages throughout the larval period, during early pupal stages, in adult female stages.
