Summary: Predicted to enable endopeptidase activator activity. Predicted to be involved in regulation of G1/S transition of mitotic cell cycle and regulation of proteasomal protein catabolic process. Predicted to act upstream of or within antigen processing and presentation of exogenous antigen. Predicted to be part of proteasome activator complex. Predicted to be active in cytoplasm and nucleoplasm. Orthologous to human PSME1 (proteasome activator subunit 1). [provided by Alliance of Genome Resources, Jan 2025]

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.
