PBA1-PBA2 proteasomal chaperone complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Chaperone complex with a role in the early stage assembly of the 26S proteasome (CPX-2262). Binds to the top of the alpha ring as it assembles, on the opposite side to the PBA3-PBA4 complex (CPX-8172) and is assumed to enforce the proper configuration of the ring and prevent the premature binding of other complexes which interact with the core barrel-shaped chamber. Release of the PBA1-PBA2 complex is one of the final stages of proteasome assembly.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
