CC -!- FUNCTION: Required for maintenance of normal mitochondrial morphology
CC (PubMed:16754953, PubMed:26071601). Required for PCP1-dependent
CC processing of MGM1 (PubMed:16754953). The UPS1:MDM35 complex mediates
CC the transfer of phosphatidic acid (PA) between liposomes and probably
CC functions as a PA transporter across the mitochondrion intermembrane
CC space (PubMed:26071602, PubMed:26071601, PubMed:26235513). Phosphatidic
CC acid release requires dissociation of the UPS1:MDM35 complex
CC (PubMed:26235513). Phosphatidic acid import is required for cardiolipin
CC (CL) synthesis in the mitochondrial inner membrane (PubMed:26071602).
CC With UPS2, controls the level of cardiolipin in mitochondria
CC (PubMed:19506038). Cardiolipin is a unique phospholipid with four fatty
CC acid chains and is present mainly in the mitochondrial inner membrane
CC where it stabilizes the electron transport chain supercomplex between
CC complexes III and IV through direct interaction of their subunits.
CC {ECO:0000269|PubMed:16754953, ECO:0000269|PubMed:19221197,

CC ECO:0000269|PubMed:26071602, ECO:0000269|PubMed:26235513}.
CC -!- SUBUNIT: Interacts with MDM35 (PubMed:20622808, PubMed:20657548,
CC PubMed:26071602, PubMed:26071601, PubMed:26235513). Found associated
CC with a 170 kDa complex. {ECO:0000269|PubMed:16754953,

CC ECO:0000269|PubMed:26235513}.
CC -!- INTERACTION:
CC Q05776; O60200: MDM35; NbExp=5; IntAct=EBI-30337, EBI-2080774;
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000269|PubMed:26235513}; Peripheral membrane protein
CC {ECO:0000269|PubMed:26235513}; Intermembrane side {ECO:0000305}.
CC Mitochondrion intermembrane space {ECO:0000269|PubMed:26235513}.
CC Note=Lacks the two major intermembrane space-targeting signals,
CC bipartite presequences and cysteine motifs, and import is mediated by
CC another IMS protein, MDM35. {ECO:0000305}.
CC -!- DISRUPTION PHENOTYPE: Cells show slow growth, fragmented mitochondria
CC and have a 50-fold reduced level of s-MGM1. These defects can be
CC complemented by human PRELI or bypassed by growth on a nonfermentable
CC carbon source. {ECO:0000269|PubMed:16754953}.
CC -!- MISCELLANEOUS: Present with 704 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the slowmo family. {ECO:0000305}.
