XKR4 ELISA kits are immunoassay tools for the measurement of the protein XK related 4, which is encoded by the XKR4 gene in humans. Functionally, this protein is known to be involved in the apoptotic pathway. The canonical protein structure is reported to have an amino acid length of 650 residues, a mass of 71.5 kDa, and is a member of the XK protein family. It is known to be localized in the cell membrane. The protein has been noted to be post-translationally cleaved. Other alias names for this target include X Kell blood group precursor-related family, member 4, X-linked Kx blood group related 4, XK, Kell blood group complex subunit-related family, member 4, and XK-related protein 4.
