Recombinant Human Nectin-4/PVRL4 Protein (RP00642)

Nectin-4 (PVRL4) is a type I transmembrane glycoprotein which belongs to the nectin family of Ig superfamilyproteins. It contains two Ig-like C2-type domains and one Ig-like V-type domain. PVRL4 seems to be involved incell adhesion through trans-homophilic and -heterophilic interactions, the latter including specificallyinteractions with nectin-1. It does not act as receptor for alpha-herpesvirus entry into cells. It is predominantlyexpressed in placenta, the embryo and breast carcinoma. But it is not detected in normal breast epithelium.The soluble form is produced by proteolytic cleavage at the cell surface (shedding), probably by ADAM17.Mutations in this gene are the cause of ectodermal dysplasia-syndactyly syndrome type 1, an autosomalrecessive disorder.
