Tomm40 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
TOMM40 (Translocase of Outer Mitochondrial Membrane 40) is a nuclear-encoded mitochondrial outer membrane protein that forms the central channel of the TOM (Translocase of Outer Mitochondrial Membrane) complex. It plays a critical role in importing nearly all nuclear-encoded mitochondrial proteins across the outer mitochondrial membrane.

TOMM40 is the core component of the TOM complex, the primary gateway for protein import into mitochondria. The TOM complex consists of multiple subunits that recognize precursor proteins, translocate them across the outer membrane, and guide them to the inner membrane translocase (TIM complex).
High expression in:
TOMM40 is located in the APOE/TOMM40 gene cluster on chromosome 19, a region strongly linked to AD risk:
