Required for cytochrome c complex (COX) IV assembly and function Protects COX assembly from oxidation-induced degradation, COX being the terminal component of the mitochondrial respiratory chain.2 Publications

Caution

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 (MT-C4D)3 Publications
The disease is caused by mutations affecting the gene represented in this entry. Patients present in late infancy or early childhood with evidence of complex IV deficiency, but the phenotype varies widely. Some patients have episodes of neurologic regression manifest as gait difficulties and spastic tetraparesis, sensorimotor polyneuropathy, and dysarthria that in some cases improved over time. Some never develop neurologic signs. Brain imaging show a cavitating leukodystrophy, predominantly affecting the posterior cerebral white matter and corpus callosum, that stabilizes or even improves over time.1 Publication
Disease descriptionA disorder of the mitochondrial respiratory chain with heterogeneous clinical manifestations, ranging from isolated myopathy to severe multisystem disease affecting several tissues and organs. Features include hypertrophic cardiomyopathy, hepatomegaly and liver dysfunction, hypotonia, muscle weakness, exercise intolerance, developmental delay, delayed motor development and mental retardation. Some affected individuals manifest a fatal hypertrophic cardiomyopathy resulting in neonatal death. A subset of patients manifest Leigh syndrome.

<p>This section provides general information on the entry.<p><a href='/help/entry_information_section' target='_top'>More...</a></p>Entry informationi

<p>This subsection of the ‘Entry information’ section provides a mnemonic identifier for a UniProtKB entry, but it is not a stable identifier. Each reviewed entry is assigned a unique entry name upon integration into UniProtKB/Swiss-Prot.<p><a href='/help/entry_name' target='_top'>More...</a></p>Entry nameiCOA8_HUMAN
<p>This subsection of the ‘Entry information’ section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called ‘Primary (citable) accession number’.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: Q96IL0
Secondary accession number(s): H7C2Z1, Q53G28
<p>This subsection of the ‘Entry information’ section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification (‘Last modified’). The version number for both the entry and the <a href="http://www.uniprot.org/help/canonical_and_isoforms">canonical sequence</a> are also displayed.<p><a href='/help/entry_history' target='_top'>More...</a></p>Entry historyiIntegrated into UniProtKB/Swiss-Prot: July 19, 2005

Last modified: September 18, 2019
This is version 120 of the entry and version 3 of the sequence. See complete history.
<p>This subsection of the ‘Entry information’ section indicates whether the entry has been manually annotated and reviewed by UniProtKB curators or not, in other words, if the entry belongs to the Swiss-Prot section of UniProtKB (<strong>reviewed</strong>) or to the computer-annotated TrEMBL section (<strong>unreviewed</strong>).<p><a href='/help/entry_status' target='_top'>More...</a></p>Entry statusiReviewed (UniProtKB/Swiss-Prot)
