Research AreasSignal Transduction

Function

Barrier-forming claudin. Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity.

Biological Context

Subcellular Location: Cell junction, tight junction; Cell membrane (Multi-pass membrane protein)
Disease Association: [CLDN3 is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region]

Subunit

Can form homo- and heteropolymers with other CLDN. Homopolymers interact with CLDN1 and CLDN2 homopolymers. Interacts in cis (within the same plasma membrane) with CLDN19 (PubMed:28028216, PubMed:36008380). Directly interacts with TJP1/ZO-1, TJP2/ZO-2 and TJP3/ZO-3 (By similarity)
