A uroplakin subtype that heterodimerizes with UROPLAKIN IA to form a component of the asymmetric unit membrane found in urothelial cells.

A uroplakin subtype that heterodimerizes with UROPLAKIN IB to form a component of the asymmetric unit membrane found in urothelial cells.

A tetraspanin domain-containing uroplakin subtype. It heterodimerizes with UROPLAKIN III to form a component of the asymmetric unit membrane found in urothelial cells.

A tetraspanin domain-containing uroplakin subtype. It heterodimerizes with UROPLAKIN II to form a component of the asymmetric unit membrane found in urothelial cells.

The epithelial lining of the URINARY TRACT.

A musculomembranous sac along the URINARY TRACT. URINE flows from the KIDNEYS into the bladder via the ureters (URETER), and is held there until URINATION.

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.

Tumors or cancer of the URINARY BLADDER.

Proteins which are found in membranes including cellular and intracellular membranes. They consist of two types, peripheral and integral proteins. They include most membrane-associated enzymes, antigenic proteins, transport proteins, and drug, hormone, and lectin receptors.

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.
