About This Section
Entrez Gene summary for CLDN4:
This gene encodes an integral membrane protein, which belongs to the claudin family. The protein is a component of
tight junction strands and may play a role in internal organ development and function during pre- and postnatal life.
This gene is deleted in Williams-Beuren syndrome, a neurodevelopmental disorder affecting multiple systems. (provided
by RefSeq, Jul 2008)

UniProtKB/Swiss-Prot: CLD4_HUMAN, O14493
Function: Plays a major role in tight junction-specific obliteration of the intercellular space (By similarity)

  • Note=CLDN4 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
