Predicted to enable molecular adaptor activity and proteasome binding activity. Predicted to be involved in chaperone-mediated protein complex assembly and proteasome core complex assembly. Predicted to act upstream of or within cerebellar granule cell precursor proliferation. Predicted to be located in Golgi apparatus; cytosol; and nucleoplasm. Predicted to be part of chaperone complex. Predicted to be active in endoplasmic reticulum. Orthologous to human PSMG1 (proteasome assembly chaperone 1).
