Summaries for TIMM17B Gene

Entrez Gene Summary for TIMM17B Gene

  • This gene encodes a multipass transmembrane protein that forms an integral component of the mitochondrial translocase TIM23 complex. This complex facilitates the transport of mitochondrial proteins from the cytosol across the mitochondrial inner membrane and into the mitochondrion. There is a pseudogene for this gene on chromosome 12. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

GeneCards Summary for TIMM17B Gene

TIMM17B (Translocase Of Inner Mitochondrial Membrane 17B) is a Protein Coding gene. Among its related pathways are Metabolism of proteins and Mitochondrial protein import.
