Protein translocation across mitochondrial membranes
... analysis of translocation through mitochondrial contact sites was greatly advanced by reversibly arresting precursor proteins in transit across the two membranes. Completion of translocation was blocked by inducing tight folding of carboxyl-terminal regions of precursors. This caused accumulation of ...
