Uroplakin 3A Antibody / UPK3A

Uroplakin 3A (UPK3A) is a component of the asymmetric unit membrane (AUM). It is a highly specialized bio-membrane made by terminally differentiated urothelial cells. Uroplakin 3A may play an important role in AUM-cytoskeleton interaction in terminally differentiated urothelial cells. It also contributes to the formation of urothelial glycocalyx, which may play an important role in preventing bacterial adherence through FimH bacterial protein binding leading to bladder infection. Uroplakin 3A has been shown as a helpful marker for the detection of bladder cancer.
