CC -!- FUNCTION: Forms a channel through the mitochondrial outer membrane that
CC allows diffusion of small hydrophilic molecules (By similarity). The
CC channel adopts an open conformation at low or zero membrane potential
CC and a closed conformation at potentials above 30-40 mV (By similarity).
CC The open state has a weak anion selectivity whereas the closed state is
CC cation-selective (By similarity). Binds various lipids, including the
CC sphingolipid ceramide, the phospholipid phosphatidylcholine, and the
CC sterol cholesterol (By similarity). Binding of ceramide promotes the
CC Binding of ceramide promotes the mitochondrial outer membrane
CC permeabilization (MOMP) apoptotic pathway (By similarity).
CC {ECO:0000250|UniProtKB:P45880}.
CC -!- SUBUNIT: Interacts with hexokinases (By similarity). Interacts with
CC ARMC12 in a TBC1D21-dependent manner (By similarity). Interacts with
CC KLC3 (By similarity). Interacts with SPATA33 (By similarity). Interacts
CC with PPP3CC in a SPATA33-dependent manner (By similarity).
CC {ECO:0000250|UniProtKB:P21796, ECO:0000250|UniProtKB:Q60930}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane
CC {ECO:0000250|UniProtKB:P45880}. Membrane
CC {ECO:0000250|UniProtKB:P45880}. Note=May localize to non-mitochondrial
CC membranes. {ECO:0000250|UniProtKB:P45880}.
CC -!- DOMAIN: Consists mainly of a membrane-spanning beta-barrel formed by 19
CC beta-strands. {ECO:0000250}.
CC -!- PTM: Ubiquitinated by PRKN during mitophagy, leading to its degradation
CC and enhancement of mitophagy. Deubiquitinated by USP30.
CC {ECO:0000250|UniProtKB:P45880}.
CC -!- SIMILARITY: Belongs to the eukaryotic mitochondrial porin family.
CC {ECO:0000305}.
