Summary: 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]

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.
