function:Specialized low-affinity urea transporter. Mediates urea transport in erythrocytes.,online information:Blood group antigen gene mutation database,polymorphism:SLC14A1 is responsible for the Kidd blood group system. The molecular basis of the Jk(a)/Jk(b) blood group antigens is a single variation in position 280; Asp-280 corresponds to Jk(a) and Asn-280 to Jk(b).,tissue specificity:Erythrocytes.,
Cell membrane ; Multi-pass membrane protein . Basolateral cell membrane ; Multi-pass membrane protein . Restricted to the basolateral membrane in various portions of the urothelium. .
Detected in erythrocytes (at protein level). Erythrocytes.
