Gene: TIMM17B (translocase of inner mitochondrial membrane 17B) Homo sapiens
Symbol: TIMM17B
Name: translocase of inner mitochondrial membrane 17B
Description: 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]
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: DXS9822; inner mitochondrial membrane preprotein translocase; JM3; mitochondrial import inner membrane translocase subunit Tim17-B; TIM17B; translocase of inner mitochondrial membrane 17 homolog B; translocase of inner mitochondrial membrane 17 homolog B (yeast)
