The Kidd blood group system has been recognized as clinically important in red blood cell RBC serology since its identification in 1951. See Blood Groups appendix. Among known blood group systems the clinically significant groups that have been identified are mostly RH KEL Kidd and Duffy.

A Jkab- Oriental person has been found whose red blood cells give a single dose reaction with anti-Jka but react more weakly than do cells from random people in tests with anti-JkaJkb. The Kidd antigen system are proteins found in the Kidds blood group which act as antigens ie they have the ability to produce antibodies under certain circumstances. An individuals blood can be typed according to.

The results support a conclusion that the antigen recognized by anti-JkaJkb is a distinct and separate antigen of the Kidd blood group system. After Rh antibodies in the Kell Duffy and Kidd blood group systems were the next in clinically significant antibodies to be revealed. The Kidd blood group system consists of 3 antigens carried on a multipass type 3 membrane glycoprotein that functions as the primary urea transporter on RBCs.

Forty years later the JK glycoprotein was determined to be a product of SCL14A1 and was identical to the urea transport protein UT-B produced by HUT11A. It consists of 389 amino acids and has 10 membrane-spanning domains.
