Protein translocation: is Hsp70 pulling my chain?

R E Jensen1, A E Johnson.   

Abstract

Hsp70 proteins in the lumen of the endoplasmic reticulum and in the mitochondrial matrix are thought to drive the translocation of proteins into each organelle. Recent experiments aimed at distinguishing between two models for Hsp70 function appear to reach opposite conclusions.
