Tjp3 Gene Summary [Mouse]
Predicted to enable cell adhesion molecule binding activity. Acts upstream of or within regulation of G1/S transition of mitotic cell cycle. Located in several cellular components, including apical plasma membrane; bicellular tight junction; and cytosol. Is expressed in alimentary system epithelium and genitourinary system. Orthologous to human TJP3 (tight junction protein 3). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Tjp3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
