ANTI-TOM20

Translocase of outer mitochondrial membrane 20 (TOMM20) is a 20kb gene with five exons and four introns, and is mapped to human chromosome 1q42.3. This gene codes for a TOMM20 receptor, which is a subunit of the outer mitochondrial membrane translocase. TOMM20 receptor contains a membrane anchor domain and a cytosolic domain, and is predominantly expressed in human cochlea.

Translocase of outer mitochondrial membrane 20 (TOMM20) is a subunit of multiple component- dynamic complex, which plays a vital role in importing certain cytosolic proteins into or through the outer membrane of the mitochondria. It acts as a receptor for precursor proteins containing N-terminal cleavable presequences targeted to the mitochondria. Nuclear respiratory factor 2(NRF-2) plays an essential role in regulating transcription of the human TOMM20 gene. TOMM20 has potential as a prognostic biomarker and therapeutic target for gastric cancer. TOMM20 serve as a marker for mitochondrial protein import in inner ear, and reduced expression of TOMM20 is associated with Meniere′s disease.
