Description
BACKGROUND Hsp70-interacting protein, Hip is one of several cochaperones that regulate activities of the Hsp70 chaperone family. Hip functions to stabilize Hsp70 in an adenosine 5′-diphosphate (ADP)–bound conformation that appears to prolong its interaction with substrate. Hsp70 cycles between 2 conformations in its role as a chaperone, an adenosine triphosphate (ATP)–bound form with low affinity for substrate and an ADP-bound form with high affinity for substrate.1 Hip-Hsp70 interaction within multichaperone complexes involved in progesterone receptor assembly in mammals has been extensively examined. Hip associates transiently with Hsp70 and the progesterone receptor at an intermediate stage in assembly of the functional receptor complex, and Hip-Hsp70 association stabilizes the receptor in a conformation that prevents premature interaction with hormone in the cytosol. Before dissociating from the complex, Hip and Hsp70 also promote association of the cochaperone Hop along with Hsp90 and other proteins with the progesterone receptor to form the mature, hormone-receptive complex.2, 3
