Summary

TIMM10 (translocase of inner mitochondrial membrane 10, HGNC:11814) is a protein-coding gene on chromosome 11q12.1, encoding Mitochondrial import inner membrane translocase subunit Tim10 (P62072). Mitochondrial intermembrane chaperone that participates in the import and insertion of multi-pass transmembrane proteins into the mitochondrial inner membrane. It is a common-essential gene (DepMap: required in 95.8% of cancer cell lines).

The mitochondrial protein encoded by this gene belongs to a family of evolutionarily conserved proteins that are organized in heterooligomeric complexes in the mitochondrial intermembrane space. These proteins mediate the import and insertion of hydrophobic membrane proteins into the mitochondrial inner membrane, functioning as intermembrane space chaperones for the highly insoluble carrier proteins.

Mitochondrial import inner membrane translocase subunit Tim10P62072 (reviewed: P62072)

All UniProt accessions (1): P62072

UniProt curated annotations — full annotation on UniProt →

Function. Mitochondrial intermembrane chaperone that participates in the import and insertion of multi-pass transmembrane proteins into the mitochondrial inner membrane. May also be 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.

Subunit / interactions. Heterohexamer; composed of 3 copies of TIMM9 and 3 copies of TIMM10/TIM10A, named soluble 70 kDa complex. The complex forms a 6-bladed alpha-propeller structure and associates with the TIMM22 component of the TIM22 complex. Interacts with multi-pass transmembrane proteins in transit. Also forms a complex composed of TIMM9, TIMM10/TIM10A and FXC1/TIM10B.

Subcellular location. Mitochondrion inner membrane.

Tissue specificity. Ubiquitous, with highest expression in heart, kidney, liver and skeletal muscle.

Domain organisation. The twin CX3C motif contains 4 conserved Cys residues that form 2 disulfide bonds in the mitochondrial intermembrane space. However, during the transit of TIMM10 from cytoplasm into mitochondrion, the Cys residues probably coordinate zinc, thereby preventing folding and allowing its transfer across mitochondrial outer membrane.

Similarity. Belongs to the small Tim family.
