RT "metalloprotease OMA1 fine-tunes mitochondrial bioenergetic function and
RT respiratory supercomplex stability.";
RL Sci. Rep. 5:13989-13989(2015).
CC -!- FUNCTION: Metalloprotease that is part of the quality control system in
CC the inner membrane of mitochondria. Activated in response to various
CC mitochondrial stress, leading to the proteolytic cleavage of target
CC proteins, such as opa1 and dele1. Following stress conditions that
CC induce loss of mitochondrial membrane potential, mediates cleavage of
CC opa1 at S1 position, leading to opa1 inactivation and negative
CC regulation of mitochondrial fusion (By similarity). Also acts as an
CC activator of the integrated stress response (ISR): in response to
CC mitochondrial stress, mediates cleavage of dele1 to generate the
CC processed form of dele1 (S-DELE1), which translocates to the cytosol
CC and activates eif2ak1/hri to trigger the ISR (By similarity). Required
CC for the stability of the respiratory supercomplexes (PubMed:26365306).
CC {ECO:0000250|UniProtKB:Q96E52, ECO:0000250|UniProtKB:Q9D8H7,
CC ECO:0000269|PubMed:26365306}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:O75844};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250|UniProtKB:O75844};
CC -!- ACTIVITY REGULATION: Protease activity is activated upon autocatalytic
CC cleavage in response to mitochondrial depolarization.
CC {ECO:0000250|UniProtKB:Q9D8H7}.
CC -!- SUBUNIT: Homooligomer. {ECO:0000250|UniProtKB:Q9D8H7}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000250|UniProtKB:Q9D8H7}; Single-pass membrane protein
CC {ECO:0000250|UniProtKB:Q9D8H7}.
CC -!- DOMAIN: The stress-sensor region regulates proteolysis and activation.
CC {ECO:0000250|UniProtKB:Q9D8H7}.
CC -!- PTM: Autocatalytically cleaved in response to mitochondrial
CC depolarization both at the N-terminus and C-terminus to generate the
CC short active form (S-OMA1). The S-OMA1 form is unstable.
CC {ECO:0000250|UniProtKB:Q9D8H7}.
CC -!- PTM: May form a redox-dependent disulfide bond (By similarity). Exists
CC in a semi-oxidized state and is activated by prolonged hypoxia (By
CC similarity). {ECO:0000250|UniProtKB:P36163,
CC ECO:0000250|UniProtKB:Q96E52}.
CC -!- DISRUPTION PHENOTYPE: Morpholino knockdown of the protein causes
CC developmental defects, such as pericardial edema, smaller eyes and
CC shorter body length (PubMed:26365306). Bioenergetics defects are
CC observed in dells (PubMed:26365306). {ECO:0000269|PubMed:26365306}.
CC -!- SIMILARITY: Belongs to the peptidase M48 family. {ECO:0000305}.
