Summary: Predicted to enable ubiquitin protein ligase binding activity. Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process and regulation of endopeptidase activity. Part of proteasome core complex. Is expressed in several structures, including central nervous system; cranium; dorsal root ganglion; lung; and tooth. Orthologous to human PSMA3 (proteasome 20S subunit alpha 3).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
