Ensembl Protein ENSP00000409544
InnateDB Gene IDBG-20463 (CLDN4)
Protein Structure
UniProt Annotation
Function Plays a major role in tight junction-specific obliteration of the intercellular space. {ECO:0000250}.
Subcellular Localization Cell junction, tight junction {ECO:0000250}. Cell membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
Disease Associations 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.
