Mitochondrial import inner membrane translocase subunit Tim22 (TIMM22)

Essential core component of the TIM22 complex, a complex that mediates the import and insertion of multi-pass transmembrane proteins into the mitochondrial inner membrane. From the TIM22 complex, it constitutes the voltage-activated and signal-gated channel.

Forms a twin-pore translocase that employs the membrane potential as external driving force in 2 voltage-dependent steps (By similarity). .
