Tjp1 Gene Summary [Rat]
Enables beta-catenin binding activity and transmembrane transporter binding activity. Involved in several processes, including cellular response to glucose stimulus; negative regulation of vascular permeability; and response to lipopolysaccharide. Located in bicellular tight junction and gap junction. Biomarker of several diseases, including brain ischemia; metabolic dysfunction and alcohol associated liver disease; peptic esophagitis; perinatal necrotizing enterocolitis; and uveitis. Orthologous to human TJP1 (tight junction protein 1). [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 rat Tjp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
