Tight Junction Protein Complex (TJ)

Target: TJ
Molecular classification: Multiprotein Complex, Scaffolding Protein, Transmembrane Protein, Adhesion Protein

Overview

The tight junction protein complex is an essential supramolecular structure responsible for regulating paracellular permeability and maintaining cellular compartmentalization across diverse tissues. Its dynamic composition allows it not only to serve as a physical barrier but also as a hub integrating structural support with signal transduction mechanisms critical for health and disease states.
