Summaries for TOMM40 Gene

Entrez Gene Summary for TOMM40 Gene

  • The protein encoded by this gene is localized in the outer membrane of the mitochondria. It is the channel-forming subunit of the translocase of the mitochondrial outer membrane (TOM) complex that is essential for import of protein precursors into mitochondria. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Aug 2015]

GeneCards Summary for TOMM40 Gene

TOMM40 (Translocase Of Outer Mitochondrial Membrane 40) is a Protein Coding gene. Diseases associated with TOMM40 include Charcot-Marie-Tooth Neuropathy Type 2A and Early-Onset, Autosomal Dominant Alzheimer Disease. Among its related pathways are Amyotrophic lateral sclerosis (ALS) and Pink/Parkin Mediated Mitophagy. Gene Ontology (GO) annotations related to this gene include porin activity and protein transmembrane transporter activity. An important paralog of this gene is TOMM40L.
