	<span style=\"line-height:1.5;\">Urea transporter UT-B is highly expressed in the membrane of erythrocytes and some epithelial and endothelial cells, in which UT-B facilitates urea transport. Recently, studies find that water, ammonia and urea analogues can also be transported by UT-B. This review mainly focuses on the transport characteristics of UT-B, and the possible physiological significance will be discussed as well.</span>
