UniProtKB - O00233 (PSMD9_HUMAN)

Protein

26S proteasome non-ATPase regulatory subunit 9

Gene

PSMD9

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Acts as a chaperone during the assembly of the 26S proteasome, specifically of the base subcomplex of the PA700/19S regulatory complex (RC). During the base subcomplex assembly is part of an intermediate PSMD9:PSMC6:PSMC3 module, also known as modulator trimer complex; PSMD9 is released during the further base assembly process.1 Publication

Caution

Was initially identified as a component of the 26S proteasome.Curated
