Target

  • Function

    Plays a major role in tight junction-specific obliteration of the intercellular space.
  • Involvement in disease

    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.
  • Sequence similarities

    Belongs to the claudin family.
  • Cellular localization

    Cell junction > tight junction. Cell membrane.
