General Information

Term

proteasome regulatory particle

ID (Ontology)

GO:0005838 (Gene Ontology)

Definition

A multisubunit complex, which caps one or both ends of the proteasome core complex. This complex recognizes and unfolds ubiquitinated proteins, and translocates them to the proteasome core complex.

Also Known As

"PA700-dependent proteasome activator"
