Protein Structure
UniProt Annotation
Function Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium- independent cell-adhesion activity (By similarity). May act as a coreceptor for HCV entry into hepatic cells. {ECO:0000250, ECO:0000269PubMed:17804490}.
Subcellular Localization Cell junction, tight junction. Cell membrane; Multi-pass membrane protein.
Disease Associations
Tissue Specificity Expressed in the liver, in peripheral blood mononuclear cells and hepatocarcinoma cell lines. {ECO:0000269PubMed:17804490}.
