Function

Multifunctional protein with enzymatic and transport activities. Probable NADPH-dependent quinone oxidoreductase which physiological substrates and function are unclear. Alternatively, has also been suggested to mediate the transfer of negatively charged phospholipids including phosphatidic acid (PA), phosphatidylserine (PS) and phosphatidylglycerol (PG) between endoplasmic reticulum and mitochondrial membranes (By similarity). Could regulate mitochondrial fusion through its interaction with mitofusins (PubMed:17105775)
