COX6C

COX6C
PFAM accession number:PF02937
Interpro abstract (IPR034884):

Cytochrome c oxidase (CcO; EC 1.9.3.1 ), a 13 subunit complex, is the terminal oxidase in the mitochondrial electron transport chain [ (PUBMED:16760263) (PUBMED:11035249) ]. This entry contains of cytochrome c oxidase subunit VIc, which is found only in eukaryotes and its specific function remains unclear. It has been reported that the relative concentrations of some nuclear encoded CcO subunits, including subunit VIc, compared to those of the mitochondrial encoded subunits, are altered significantly during the progression of prostate cancer [ (PUBMED:12973739) ].

This entry also includes Dictyostelium cytochrome c oxidase VIIs, an alternative subunit VII isoform produced under hypoxia [ (PUBMED:9049303) ].
