PBA3-PBA4 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 bottom of the alpha ring as it assembles, on the opposite side to the PBA1-PBA2 complex (CPX-8171) 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. PBA3-PBA4 appears to disengage shortly after completion of the alpha-ring.
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.
