40 kDa heat shock protein (hsp40) is a novel heat shock protein induced by heat shock and other stresses in mammalian and avian cells. The cDNA sequence of the hsp40 is identical with HDJ1. Deduced amino acid sequence of the hsp40 cDNA is homologues to DnaJ, an E. coli heat shock protein and its homologues in yeast such as SCJ1, YDJ1 (MAS5), SIS1, SEC63 and zuotin. E coli?s DnaJ heat shock protein is known to function together with DnaK (hsp70) and GrpE as a molecular chaperone, which is necessary for assembly and disassembly of protein complexes, protein folding, renaturation of denatured proteins, prevention of protein aggregation and protein export. The hsp40 is colocarized with hsp70 in the nuclei and nucleoli of heat-shocked HeLa cells which suggests that hsp70 (DnaK)-hsp40 (DnaJ) chaperone system is ubiquitous.

This antibody was purified from mouse ascites fluid using protein A agarose. This hybridoma (clone 2E1) was established by fusion of mouse myeloma cell P3U1 with Balb/c splenocyte immunized with full-length human HSP40 (1-340 aa).
