Gene: PSMA1 (proteasome 20S subunit alpha 1) Homo sapiens
Symbol: PSMA1
Name: proteasome 20S subunit alpha 1
Description: Predicted to have endopeptidase activity. Predicted to be involved in proteasomal ubiquitin-independent protein catabolic process and proteasome-mediated ubiquitin-dependent protein catabolic process. Localizes to centrosome; nucleoplasm; and proteasome complex.
Type: protein-coding
RefSeq Status: REVIEWED
