Protein Structure

UniProt Annotation

Function

Promotes mitochondrial protein synthesis. May act as a fidelity factor of the translation reaction, by catalyzing a one- codon backward translocation of tRNAs on improperly translocated ribosomes. Binds to mitochondrial ribosomes in a GTP-dependent manner. {ECO:0000255HAMAP-Rule:MF_03137}.

Subcellular Localization

Mitochondrion inner membrane {ECO:0000255HAMAP-Rule:MF_03137}; Peripheral membrane protein {ECO:0000255HAMAP-Rule:MF_03137}; Matrix side {ECO:0000255HAMAP- Rule:MF_03137}.
