Protein MGARP (Mgarp)

Plays a role in the trafficking of mitochondria along microtubules. Regulates the kinesin-mediated axonal transport of mitochondria to nerve terminals along microtubules during hypoxia.

Participates in the translocation of TRAK2/GRIF1 in the cytoplasm into the mitochondrion. Plays a role in steroidogenesis through maintenance of mitochondrial abundance and morphology.
