Protein
Mitochondrial protein import protein ZIM17
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Involved in protein import into mitochondria. Acts as a Hsp70-specific chaperone that prevents self-aggregation of the matrix Hsp70 chaperones SSC1 (mtHSP70) and SSQ1, thereby maintaining their function in mitochondrial protein import and Fe/S protein biosynthesis. May act together with PAM18 as co-chaperone to facilitate recognition and folding of imported proteins by SSC1 in the mitochondrial matrix.
