General Information

EC Number General Information Comment Organism
3.6.4.10 physiological function co-chaperones help to maintain cellular homeostasis by modulating the activities of molecular chaperones involved in protein quality control. The HSP70/HSP90-organizing protein (HOP) is a co-chaperone that cooperates with HSP70 and HSP90 in catalysis of protein folding and maturation in the cytosol. HOP has ATP-binding activity comparable to that of HSP70/HSP90, and that HOP slowly hydrolyzes ATP. The ATPase domain of HOP locates in the N-terminal TPR1-DP1-TPR2A segment. HOP changes its conformation in the presence of ATP, its ATPase activity is unaffected by the D186A mutation Sus scrofa
