CHIP is a dimeric U box E3 ubiquitin ligase that binds Hsp90 and/or Hsp70 via its TPR-domain, facilitating ubiquitylation of chaperone bound client proteins. We have determined the crystal structure of CHIP bound to an Hsp90 C-terminal decapeptide. The structure explains how CHIP associates with either chaperone type and reveals an unusual asymmetric homodimer in which the protomers adopt radically different conformations ...
