Summary: Predicted to enable endopeptidase activity. Predicted to be involved in fat cell differentiation; proteasomal protein catabolic process; and regulation of endopeptidase activity. Predicted to act upstream of or within antigen processing and presentation. Predicted to be located in cytoplasm. Predicted to be part of proteasome core complex, beta-subunit complex and spermatoproteasome complex. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in JMP syndrome. Orthologous to human PSMB8 (proteasome 20S subunit beta 8). [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.
