RT "MARCH-V is a novel mitofusin 2- and Drp1-binding protein able to change
RT mitochondrial morphology.";
RL EMBO Rep. 7:1019-1022(2006).
CC -!- FUNCTION: Mitochondrial E3 ubiquitin-protein ligase that plays a
CC crucial role in the control of mitochondrial morphology by acting as a
CC positive regulator of mitochondrial fission. May play a role in the
CC prevention of cell senescence acting as a regulator of mitochondrial
CC quality control. Promotes ubiquitination of FIS1, DNM1L and MFN1.
CC {ECO:0000250|UniProtKB:Q9NX47}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.;
CC EC=2.3.2.27;
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC -!- SUBUNIT: Monomer and homodimer. Interacts with MFN1, MFN2, DNM1L and
CC FIS1. {ECO:0000250|UniProtKB:Q9NX47}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane
CC {ECO:0000250|UniProtKB:Q9NX47}; Multi-pass membrane protein
CC {ECO:0000255}. Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q9NX47}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- DOMAIN: The RING-CH-type zinc finger domain is required for E3 ligase
CC activity. {ECO:0000255|PROSITE-ProRule:PRU00623}.
CC -!- PTM: Autoubiquitinated leading to degradation (short half-life).
