Anti-FAM77D antibodies enable researchers to detect and measure the FAM77D antigen in biological samples. This target is a reported synonym of the NKAIN3 gene, which encodes sodium/potassium transporting ATPase interacting 3. This protein is known to function in the transport of ions, among other biological roles. The human version of FAM77D has a canonical amino acid length of 197 residues and a protein mass of 22.6 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in the colon, cerebral cortex, cerebellum, caudate, and appendix. FAM77D is a member of the NKAIN protein family.
