CC -!- FUNCTION: Chaperone protein which promotes assembly of the 20S
CC proteasome as part of a heterodimer with PSMG1. The PSMG1-PSMG2
CC heterodimer binds to the PSMA5 and PSMA7 proteasome subunits, promotes
CC assembly of the proteasome alpha subunits into the heteroheptameric
CC alpha ring and prevents alpha ring dimerization.
CC {ECO:0000269|PubMed:16251969, ECO:0000269|PubMed:17707236}.
CC -!- SUBUNIT: Forms a heterodimer with PSMG1. The PSMG1-PSMG2 heterodimer
CC interacts directly with the PSMA5 and PSMA7 proteasome alpha subunits.
CC {ECO:0000269|PubMed:16251969}.
CC -!- INTERACTION:

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9EST4}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q969U7-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q969U7-2; Sequence=VSP_055721;
CC -!- TISSUE SPECIFICITY: Widely expressed with highest levels in lung, brain
CC and colon. Moderately expressed in muscle, stomach, spleen and heart.
CC Weakly expressed in small intestine, pancreas and liver. Highly
CC expressed in hepatocellular carcinomas with low levels in surrounding
CC liver tissue. {ECO:0000269|PubMed:11854909}.
CC -!- PTM: Degraded by the proteasome upon completion of 20S proteasome
CC maturation. {ECO:0000269|PubMed:16251969}.
CC -!- DISEASE: Proteasome-associated autoinflammatory syndrome 4 (PRAAS4)
CC [MIM:619183]: An autosomal recessive, autoinflammatory disorder
CC characterized by panniculitis and erythematous skin lesions apparent in
CC early infancy. Additional features include hepatosplenomegaly,
CC lymphadenopathy, autoimmune hemolytic anemia, fever, generalized
CC lipodystrophy, myositis, joint contractures, and mild motor and speech
CC delay. {ECO:0000269|PubMed:30664889}. Note=The disease may be caused by
CC variants affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the PSMG2 family. {ECO:0000255}.
