Enables Hsp90 protein binding activity and kinase binding activity. Contributes to protein kinase regulator activity. Involved in positive regulation of mitophagy in response to mitochondrial depolarization; posttranscriptional regulation of gene expression; and regulation of protein kinase activity. Located in cytosol. Part of HSP90-CDC37 chaperone complex. Is expressed in 2-cell stage embryo and 4-cell stage embryo. Orthologous to human CDC37 (cell division cycle 37, HSP90 cochaperone).
