Research Backgrounds
Channel-forming tight junction protein that mediates paracellular chloride transport in the kidney. Plays a critical role in the paracellular reabsorption of filtered chloride in the kidney collecting ducts. Claudins play a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity.
Phosphorylated. Phosphorylation by EPHA2 is stimulated by EFNA1 and alters interaction with TJP1.
Cell junction>Tight junction. Cell membrane>Multi-pass membrane protein.
Note: CLDN4 is required for tight junction localization in the kidney.
Directly interacts with TJP1/ZO-1. Interacts with TJP2/ZO-2 and TJP3/ZO-3 (By similarity). Interacts with EPHA2; phosphorylates CLDN4 and may regulate tight junctions. Interacts with CLDN1. Interacts with CLDN8 (By similarity).
(Microbial infection) Interacts (via both extracellular domains) with Clostridium perfringens enterotoxin CPE; the interaction may disrupt claudin assembly in tight junctions.
Belongs to the claudin family.
