Anti-HSP40

HSP40 and HSP40-like proteins represent a large family of chaperone proteins that are homologous to E. coli DnaJ protein. HSP40 family proteins bind unfolded proteins, prevent their aggregation, and then deliver them to HSP70. Another major function of HSP40 is to stimulate ATPase activity of HSP70, which causes conformational change of the unfolded proteins. Protein function: Interacts with HSP70 and can stimulate its ATPase activity. Stimulates the association between HSC70 and HIP. Negatively regulates heat shock-induced HSF1 transcriptional activity during the attenuation and recovery phase period of the heat shock response (PubMed:9499401). Stimulates ATP hydrolysis and the folding of unfolded proteins mediated by HSPA1A/B (in vitro) (PubMed:24318877). [The UniProt Consortium] Recommended dilutions: WB 1:500-1,000  IHC 1:100-200.
