XK (also known as Kell blood group precursor) is a protein found on human red blood cells and other tissues which is responsible for the Kx antigen which helps determine a person's blood type. The Kx antigen plays a role in matching blood for blood transfusions. Absence of XK protein leads to McLeod syndrome, a multi-system disorder characterized by hemolytic anemia, myopathy, acanthocytosis, and chorea. ^[1]

XK is located on the X chromosome and absence of the XK protein is an X-linked disease.^[1] XK is a membrane transport protein of unknown action.^[1]
