Protein
Mitochondrial import inner membrane translocase subunit TIM10
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Mitochondrial intermembrane chaperone that participates in the import and insertion of multi-pass transmembrane proteins into the mitochondrial inner membrane. Also required for the transfer of beta-barrel precursors from the TOM complex to the sorting and assembly machinery (SAM complex) of the outer membrane. Acts as a chaperone-like protein that protects the hydrophobic precursors from aggregation and guide them through the mitochondrial intermembrane space. Compared to TIM9, it may function as a substrate sensor.
Similarity
Belongs to the small Tim family.
