Psma3 - proteasome subunit alpha 3

Predicted to enable ubiquitin protein ligase binding activity. Predicted to be involved in proteasomal protein catabolic process and regulation of endopeptidase activity. Part of proteasome core complex. Is expressed in several structures, including alimentary system; central nervous system; cranium; dorsal root ganglion; and lung. Orthologous to human PSMA3 (proteasome 20S subunit alpha 3). [provided by Alliance of Genome Resources, Apr 2022]
