SUMMARY PARAGRAPH for JID1

Hsp40/DnaJ is a family of proteins, established by bacterial DnaJ, that regulates Hsp70 chaperone activity. Hsp40s stimulate the intrinsically weak ATPase activity of Hsp70 proteins and facilitate Hsp70 interaction with polypeptide substrates. Hsp70 family members often have multiple Hsp40 partners, and these specific pairings govern Hsp70 chaperone involvement in particular processes (reviewed in 3, 4, and 5). All Hsp40s contain a highly conserved 75-amino acid J domain, which interacts with the ATPase domain of Hsp70 to stimulate ATP hydrolysis. However, there are also other conserved structural domains, and based on the presence or absence of these regions, the Hsp40 family can be divided into three subtypes: type I, type II and type III (a comprehensive overview of the structural features of the different HSP40 subtypes can be found in 5). Sequence analysis of the S. cerevisiae genome has revealed 22 proteins in the Hsp40/DnaJ family: YDJ1, XDJ1, APJ1, SIS1, DJP1, ZUO1, SWA2, JJJ1, JJJ2, JJJ3, CAJ1, CWC23, MDJ1, MDJ2, PAM18, JAC1, JID1, SCJ1, HLJ1, JEM1, SEC63, and ERJ5 (5).
