Summary: Enables endopeptidase activity. Involved in proteasomal ubiquitin-independent protein catabolic process; proteasome core complex assembly; and proteasome-mediated ubiquitin-dependent protein catabolic process. Located in peroxisome. Part of proteasome core complex, beta-subunit complex. Human ortholog(s) of this gene implicated in proteasome-associated autoinflammatory syndrome 1. Orthologous to several human genes including PSMB5 (proteasome 20S subunit beta 5). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Deletion of the N-terminal half of the beta5 propeptide causes substantial defects in proteasome assembly.
Title: Distinct Elements in the Proteasomal β5 Subunit Propeptide Required for Autocatalytic Processing and Proteasome Assembly.
Data suggest regulated process for removal of proteasomes upon nitrogen starvation; autophagy involves separate processes for dissociation and nuclear export of core (PRE2) and regulatory (RPN1) proteins; only core protein autophagy depends on UBP3.
Title: Starvation Induces Proteasome Autophagy with Different Pathways for Core and Regulatory Particles.
Data indicate that the dynamic gate can be opened by allosteric coupling to a tetrahedral transition state at any of the working active centers of proteasome.
Title: A tetrahedral transition state at the active sites of the 20S proteasome is coupled to opening of the alpha-ring channel.
