<p>The COA7 gene encodes a protein that localizes to the mitochondria and is involved in the assembly of mitochondrial complex IV, which is the terminal component of the mitochondrial respiratory chain (summary by Martinez Lyons et al., 2016). </p><p>COA7 is predicted to have a role in assembling mitochondrial complexes that function in oxidative phosphorylation (Kozjak-Pavlovic et al., 2014). </p>

<strong>Cloning and Expression</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Kozjak-Pavlovic et al. (2014) reported that human COA7, which they called C1ORF163, encodes a 231-amino acid protein that shares sequence similarity with beta-lactamase (LACTB; 608440). The protein is rich in cysteine and has 5 predicted Sel1-like repeats (SLRs). SLRs share similarity with C. elegans Sel1 (see 602329) and are predicted to be involved in protein-protein interactions. C1ORF163 localized to mitochondria in HeLa cells. Extraction and swelling experiments revealed that C1ORF163 is a soluble protein of the inner mitochondrial space. Database analysis found conservation of C1ORF163 from bacteria to human. </p><p>Higuchi et al. (2018) found expression of the COA7 gene in the cytoplasm of Schwann cells of human sural nerve. </p>

<strong>Gene Function</strong>

</div>
<span class="mim-text-font">
<p>Kozjak-Pavlovic et al. (2014) found that knockdown of SAM50 (SAMM50; 612058) or mitofilin (IMMT; 600378) in HeLa cells reduced the protein content of C1ORF163. Knockdown of C1ORF163 via short hairpin RNA reduced the content of mitochondrial complex IV proteins and the number of mature complex IV complexes. Knockdown of C1ORF163 had weaker effects on complex I, III, and V proteins, and had no effect on complex II proteins. Knockdown of C1ORF163 reduced complex IV activity, with weaker effects on the activities of complexes I and V. Knockdown of C1ORF163 had no effect on mitochondrial morphology, membrane potential, or protein import. Native gel electrophoresis detected C1ORF163 in several soluble protein complexes of the inner mitochondrial space, and knockdown experiments showed that the endogenous protein was present in complexes with apparent molecular masses of 60 and 150 kD. </p><p>Martinez Lyons et al. (2016) determined that the COA7 is a soluble protein that predominantly localizes to the mitochondrial matrix, although some appeared to be associated with the inner mitochondrial membrane. </p><p>Using affinity purification, mass spectrometry, and Western blot analyses in human Flp-In T-Rex 293 cells, Mohanraj et al. (2019) found that COA7 interacted with MIA40 (CHCHD4; 611077) through disulfide bonds. COA7 was a substrate of MIA40 that was synthesized in the cytosol and imported to the mitochondrial intermembrane space in a manner dependent on MIA40. </p>

The mutations, which were found by whole-exome sequencing and confirmed by Sanger sequencing, segregated with the disorder in the family.

The mutations, which were found by exome sequencing and confirmed by Sanger sequencing, segregated with the disorder in the families. Expression of some of the variants in HeLa cells showed that they localized normally to the mitochondria. The mutations were postulated to result in a loss of function with a neurodegenerative effect.

<p>Higuchi et al. (2018) found that knockdown of the Drosophila Coa7 gene caused morphologically aberrant rough eyes with fusion of ommatidia and lack of bristles compared to controls. Mutant flies also showed a shorter life span and locomotor defects, which were associated with abnormalities in the formation of motor neurons at presynaptic terminals at the neuromuscular junction (NMJ). However, Higuchi et al. (2018) suggested that the NMJ abnormalities may be a secondary effect of axonal changes in the peripheral nervous system. </p>

The mutations, which were found by whole-exome sequencing and confirmed by Sanger sequencing, segregated with the disorder in the family. Neither was reported in the ExAC database. Patient cells showed no detectable COA7 protein, decreased amounts of COX structural subunits MTCO2 (516040) and MTCO3 (516050), and decreased levels of fully assembled complex IV.

The mutation, which was found by whole-exome sequencing and confirmed by Sanger sequencing, segregated with the disorder in the family. The variant was found at a low frequency in heterozygous state in the ExAC database (1 in 120,268 alleles), but was not present in the dbSNP (build 137), 1000 Genomes Project, or Exome Sequencing Project databases. Two additional unrelated Japanese patients with a similar disorder were found to be compound heterozygous for D6G and a different mutation in the COA7 gene: a 28-year-old man (patient 3) carried a c.446G-T transversion, resulting in a ser149-to-ile (S149I; 615623.0004) substitution at a conserved residue on the other allele, and a 27-year-old man (patient 4) carried a 1-bp deletion (c.430delG; 615623.0005), resulting in a frameshift and premature termination (Gly144fs), on the other allele. The 2 additional variants were not found in any of the public databases. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
