Anti-C9orf54 antibodies enable researchers to detect and measure the C9orf54 antigen in biological samples. This target is a reported synonym of the MIGA2 gene, which encodes mitoguardin 2. This protein is known to function in bone development, among other biological roles. The human version of C9orf54 has a canonical amino acid length of 593 residues and a protein mass of 65.5 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. C9orf54 is a member of the Mitoguardin protein family.
