Mitochondrial import inner membrane translocase subunit TIM18

UniProtKB accession:  Q08749

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the TIM22 complex, a complex that mediates the import and insertion of multi-pass transmembrane proteins into the mitochondrial inner membrane. The TIM22 complex forms a twin-pore translocase that uses the membrane potential as external driving force. Its role in the complex is unclear but it may be involved in the assembly and stabilization of the TIM22 complex.
