About CLDN2

Cytogenetic location: Xq22.3 Genomic coordinates (GRCh38): X:106,900,164-106,930,861 (from NCBI)

This gene has 3 transcripts (splice variants), 188 orthologues, 22 paralogues and is associated with 1 phenotype. Biased expression in kidney (RPKM 67.4), gall bladder (RPKM 59.4) and 4 other tissues.

Summary

This gene product belongs to the claudin protein family whose members have been identified as major integral membrane proteins localized exclusively at tight junctions. Claudins are expressed in an organ-specific manner and regulate tissue-specific physiologic properties of tight junctions. This protein is expressed in the intestine. Alternatively spliced transcript variants with different 5' untranslated region have been found for this gene.[provided by RefSeq, Jan 2010]
