Predicted to enable molecular adaptor activity. Predicted to be involved in chaperone-mediated protein complex assembly and proteasome assembly. Predicted to act upstream of or within mitotic spindle assembly checkpoint signaling and negative regulation of apoptotic process. Predicted to be part of chaperone complex. Predicted to be active in cytosol and nucleus. Orthologous to human PSMG2 (proteasome assembly chaperone 2). [provided by Alliance of Genome Resources, Apr 2022]
