It is uncertain whether Met-1 or Met-14 is the initiator. However, according to some experiments, Met-14 seems to be the initiator.2 Publications
First thought to play a role in the regulation of apoptosis, mediating mitochondria-induced cell death in vascular smooth muscle cells through the release of cytochrome c (COX) from mitochondria and the activation of the caspase cascade (By similarity). However, recent studies show that it is not directly involved in apoptosis regulation but in the protection of COX from oxidatively induced degradation (PubMed:30552096, PubMed:25175347).By similarity2 Publications

Mitochondrial complex IV deficiency, nuclear type 17 (MC4DN17)3 Publications
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionAn autosomal recessive mitochondrial disorder with highly variable clinical manifestations and severity. Clinical features vary from acute neurometabolic decompensation in late infancy to subtle neurological signs presenting in adolescence. Encephalopathic episodes are characterized by acute loss of developmental milestones including ability to walk or sit, loss of speech, episodes with somnolence and seizure, and pyramidal signs rapidly evolving into spastic tetraparesis. The clinical course subsequently tends to stabilize and in several subjects marked recovery of neurological milestones is observed over time. Brain imaging shows a cavitating leukodystrophy, predominantly involving the posterior cerebral white matter and the corpus callosum in the acute stage, after which the abnormalities partially improve and then stabilize. Patient tissues show variably decreased levels and activity of mitochondrial respiratory complex IV.
