hsp60 is implicated in mitochondrial protein import and macromolecular assembly. it may facilitate the correct folding of imported proteins, and may also prevent misfolding and promote the refolding and proper assembly of unfolded polypeptides generated under stress conditions in the mitochondrial matrix. hsp60 interacts with hras and with hbv protein x and htlv-1 protein p40tax. hsp60 belongs to the chaperonin (hsp60) family. note: this description may include information from uniprotkb.
