HSP70/DnaK Substrate Peptide – Growth Factors and Cytokines

Model substrate peptide for heat shock protein 70 (HSP70)/ Chaperone protein DnaK. Binds to the substrate binding domain of DnaK and is used in co-crystallisation assays. DnaK is the most well studied heat shock proteins and is central in protein folding and in shuttling misfolded peptides to other chaperones and proteases for resolution. In the presence of ADP, this substrate peptide interacts with DnaK with high affinity, however when ATP is bound to DnaK, substrate binding is far weaker.
