Psmg1 - proteasome (prosome, macropain) assembly chaperone 1

Enables proteasome binding activity. Acts upstream of or within cerebellar granule cell precursor proliferation and proteasome core complex assembly. Predicted to be located in Golgi apparatus; cytosol; and nucleoplasm. Predicted to be part of chaperone complex. Predicted to be active in endoplasmic reticulum. Is expressed in several structures, including alimentary system; genitourinary system; heart; nervous system; and sensory organ. Orthologous to human PSMG1 (proteasome assembly chaperone 1).
