Tomm40 - translocase of outer mitochondrial membrane 40

Enables cation channel activity; preprotein binding activity; and protein transmembrane transporter activity. Involved in positive regulation of apoptotic process; protein insertion into mitochondrial membrane; and protein targeting to mitochondrion. Located in mitochondrial outer membrane. Is integral component of mitochondrial outer membrane. Part of mitochondrial outer membrane translocase complex. Human ortholog(s) of this gene implicated in cerebral infarction. Orthologous to human TOMM40 (translocase of outer mitochondrial membrane 40). [provided by Alliance of Genome Resources, Apr 2022]
