Product Info

• Predicted Species Reactivity: Homo sapiens|Human
• Product Format: Liquid. In Dulbecco’s PBS.
• Host: E. Coli
• Application: WB, EMSA
• Additional Information: Hsp40/Hdj1 is a cytosolic co-chaperone belonging to the class DnaJ, named after its homolog in E. Coli. Hsp40 functions in protein folding by binding nascent peptides and unfolded substrates and facilitating substrate interaction with Hsp70. Binding of Hsp40 to Hsp70 increases Hsp70 ATP hydrolysis and substrate binding, which is reversed by the action of nucleotide exchange factors (GrpE in E. Coli). Repeated cycles of Hsp40/Hsp70 peptide binding and ATP hydrolysis prevent premature folding and aggregation, promoting protein maturation throughout the cell.
• Reconstitution and Storage: Store at -80C

• Description of Target: 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).
