Anti-Sel1 repeat containing 1 antibodies enable researchers to detect and measure the Sel1 repeat containing 1 antigen in biological samples. This target is a reported synonym of the COA7 gene, which encodes cytochrome c oxidase assembly factor 7. This protein is known to be required for assembly of mitochondrial respiratory chain complex I and complex IV. The human version of Sel1 repeat containing 1 has a canonical amino acid length of 231 residues and a protein mass of 25.7 kilodaltons. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Sel1 repeat containing 1 is a member of the Hcp beta-lactamase protein family.
