Summaries for TIMM8B Gene

Entrez Gene Summary for TIMM8B Gene

  • This gene encodes a member of a well-conserved family of proteins with similarity to yeast Tim mitochondrial import proteins. This gene is encoded by a nuclear gene and is transported into the intermembrane space of the mitochondrion. When formed into complexes, these proteins guide membrane-spanning proteins across the mitochondrial intermembrane space before they are added into the mitochondrial inner membrane. This gene is adjacent to succinate dehydrogenase, subunit D (SDHD), in which mutations have been found in affected members of families with hereditary paraganglioma.[provided by RefSeq, Aug 2009]

GeneCards Summary for TIMM8B Gene

TIMM8B (Translocase Of Inner Mitochondrial Membrane 8 Homolog B (Yeast)) is a Protein Coding gene. Among its related pathways are Transport to the Golgi and subsequent modification and Mitochondrial protein import. An important paralog of this gene is TIMM8A.

UniProtKB/Swiss-Prot for TIMM8B Gene

  • Probable mitochondrial intermembrane chaperone that participates in the import and insertion of some 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 (By similarity).

UniProtKB/Swiss-Prot:

TIM8B_HUMAN :
  • The twin CX3C motif contains 4 conserved Cys residues that form 2 disulfide bonds in the mitochondrial intermembrane space. However, during the transit of TIMM8B from cytoplasm into mitochondrion, the Cys residues probably coordinate zinc, thereby preventing folding and allowing its transfer across mitochondrial outer membrane (By similarity).
  • Belongs to the small Tim family.
