Recombinant Human Uroplakin-1b (UPK1B), Truncated

Uniprot Id

O75841

Target Species

Human

Target Name

UPK1B

Target Full Name

Uroplakin-1b

Target Function

Component of the asymmetric unit membrane (AUM); a highly specialized biomembrane elaborated by terminally differentiated urothelial cells. May play an important role in normal bladder epithelial physiology, possibly in regulating membrane permeability of superficial umbrella cells or in stabilizing the apical membrane through AUM/cytoskeletal interactions.

Target Subcellular Location

Membrane; Multi-pass membrane protein.

Target Protein Families

Tetraspanin (TM4SF) family

Target Tissue Specificity

Bladder epithelium.

Target Synonyms

UPK1B; TSPAN2; Uroplakin-1b; UP1b; Tetraspanin-20; Tspan-20; Uroplakin Ib; UPIb

Target Background

The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is found in the asymmetrical unit membrane (AUM) where it can form a complex with other transmembrane 4 superfamily proteins. It may play a role in normal bladder epithelial physiology, possibly in regulating membrane permeability of superficial umbrella cells or in stabilizing the apical membrane through AUM/cytoskeletal interactions. The use of alternate polyadenylation sites has been found for this gene.
