Enables several functions, including chaperone binding activity; misfolded protein binding activity; and protein kinase inhibitor activity. Involved in cellular response to cold; proteolysis involved in cellular protein catabolic process; and regulation of translational initiation. Located in cytosol and endoplasmic reticulum lumen. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and liver and biliary system. Orthologous to human DNAJC3 (DnaJ heat shock protein family (Hsp40) member C3). [provided by Alliance of Genome Resources, Apr 2022]
