. Mgr2 promotes coupling of the mitochondrial presequence translocase to partner complexes. J Cell Biol. 2012;197:595-604 pubmed publisher
..We have identified a new subunit of the TIM23 complex, the inner membrane protein Mgr2. Mitochondria lacking Mgr2 were deficient in the Tim21-containing sorting form of the TIM23 complex...

. Mgr2 functions as lateral gatekeeper for preprotein sorting in the mitochondrial inner membrane. Mol Cell. 2014;56:641-52 pubmed publisher
..We report that the small hydrophobic protein Mgr2 controls the lateral release of preproteins. Mgr2 interacts with preproteins in transit through the TIM23 complex...

..Thus, a replenishment cycle of co-chaperones at the TIM23 complex is an integral part of Hsp70's ATPase cycle at the channel exit site and essential to maintain motor-driven mitochondrial protein import. ..

. Two distinct membrane potential-dependent steps drive mitochondrial matrix protein translocation. J Cell Biol. 2017;216:83-92 pubmed publisher
..The ??- and Pam17-dependent import step identified in this study is positioned between the two known energy-dependent steps: ??-driven presequence translocation and adenosine triphosphate-driven import motor activity. ..
