Enzyme ClassNot Available
Biological Properties
General Functionpositive regulation of phosphatidylcholine biosynthetic process
Specific FunctionRequired for maintenance of normal mitochondrial morphology (PubMed:16754953, PubMed:26071601). Required for PCP1-dependent processing of MGM1 (PubMed:16754953). The UPS1:MDM35 complex mediates the transfer of phosphatidic acid (PA) between liposomes and probably functions as a PA transporter across the mitochondrion intermembrane space (PubMed:26071602, PubMed:26071601, PubMed:26235513). Phosphatidic acid release requires dissociation of the UPS1:MDM35 complex (PubMed:26235513). Phosphatidic acid import is required for cardiolipin (CL) synthesis in the mitochondrial inner membrane (PubMed:26071602). With UPS2, controls the level of cardiolipin in mitochondria (PubMed:19506038). Cardiolipin is a unique phospholipid with four fatty acid chains and is present mainly in the mitochondrial inner membrane where it stabilizes the electron transport chain supercomplex between complexes III and IV through direct interaction of their subunits.
