What role do the Hsp70 proteins play in delivering proteins to their site of action such as the mitochondria?
A)aids in proper folding to allow protein to properly traverse membranes
B)prevents proteolysis of the unfolded protein
C)keeps the protein in an unfolded state to allow transfer across membranes
D)aids in formation of an intermediate folded protein that is present only during membrane transport
E)none of the above

Question

Quizplus · Accepted Answer

Hsp70 proteins bind to nascent or unfolded polypeptides to keep them in an unfolded state, which is necessary for their translocation across mitochondrial membranes.
