Uroplakin Ia
A tetraspanin domain-containing uroplakin subtype. It heterodimerizes with UROPLAKIN II to form a component of the asymmetric unit membrane found in urothelial cells.
Uroplakin Ib
A tetraspanin domain-containing uroplakin subtype. It heterodimerizes with UROPLAKIN III to form a component of the asymmetric unit membrane found in urothelial cells.
Uroplakin III
A uroplakin subtype that heterodimerizes with UROPLAKIN IB to form a component of the asymmetric unit membrane found in urothelial cells.
Uroplakin II
Tetraspanins
A large superfamily of cell surface membrane proteins characterized by their four transmembrane domains. They play a role in a variety of processes such as cellular adhesion and motility. They may be involved in the organization of cell surface MEMBRANE MICRODOMAINS that regulate the activation of LEUKOCYTES.
Uroplakins
Specialized membrane glycoproteins that are found on UROTHELIUM cells. They associate into a hexagonal array of 16-nm cell surface particles which form the asymmetric unit membrane of urothelial plaques.
