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]. * **UniProt Summary**: Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium- independent cell-adhesion activity. {ECO:0000250}. |PMP22 Claudin| |calcium-independent cell-cell adhesion via plasma membrane cell-adhesion molecules| |bicellular tight junction| |structural molecule activity| |cell-cell adhesion via plasma-membrane adhesion molecules| |cell-cell adhesion| |cell adhesion| |biological adhesion| |identical protein binding| \\ === CRISPR Data === No hits were found.
