Anti-XKR1 antibodies enable researchers to detect and measure the XKR1 antigen in biological samples. This target is a reported synonym of the XK gene, which encodes X-linked Kx blood group antigen, Kell and VPS13A binding protein. This protein is known to function in the regulation of intracellular calcium, among other biological roles. The human version of XKR1 has a canonical amino acid length of 444 residues and a protein mass of 50.9 kilodaltons. It is reported to be localized in the ER of cells and notably expressed in the skin, skeletal muscle, heart muscle, endometrium, and cerebellum. Other names for this target antigen include KX, NA, and NAC. Indicated applications for XKR1 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
