General annotation (Comments)

Function	Metalloprotease that is part of the quality control system in the inner membrane of mitochondria. Following stress conditions that induce loss of mitochondrial membrane potential, mediates cleavage of OPA1 at S1 position, leading to OPA1 inactivation and negative regulation of mitochondrial fusion. Its role in mitochondrial quality control is essential for regulating lipid metabolism as well as to maintain body temperature and energy expenditure under cold-stress conditions. Ref.6
Cofactor	Binds 1 zinc ion per subunit Potential.
Subcellular location	Mitochondrion inner membrane; Multi-pass membrane protein Probable Ref.6.
Tissue specificity	Widely expressed, with strong expression in the heart, skeletal muscle, kidney and liver. Ref.1
Post-translational modification	In normal conditions, cleaved into an inactive 40 kDa form. Following CCCP treatment that induces loss of mitochondrial membrane potential, the 40 kDa form is reduced in favor of an active 60 kDa form. Ref.6
Sequence similarities	Belongs to the peptidase M48 family.
Caution	Was initially reported to localize in the endoplasmic reticulum (Ref.1). However, it was later shown that it localizes to mitochondrion (Ref.6).
Sequence caution	The sequence BAC03583.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence CAI13522.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI13523.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI13524.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI13525.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI13526.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI22238.1 differs from that shown. Reason: Erroneous gene model prediction.
