Function NECT4_HUMAN Seems to be involved in cell adhesion through trans-homophilic and -heterophilic interactions, the latter including specifically interactions with NECTIN1. Does not act as receptor for alpha-herpesvirus entry into cells. (Microbial infection) Acts as a receptor for measles virus. Publication Abstract from PubMed Nectins are immunoglobulin superfamily glycoproteins that mediate intercellular adhesion in many vertebrate tissues. Homophilic and heterophilic interactions between nectin family members help mediate tissue patterning. We determined the homophilic binding affinities and heterophilic specificities of all four nectins and the related protein nectin-like 5 (Necl-5) from human and mouse, revealing a range of homophilic interaction strengths and a defined heterophilic specificity pattern. To understand the molecular basis of their adhesion and specificity, we determined the crystal structures of natively glycosylated full ectodomains or adhesive fragments of all four nectins and Necl-5. All of the crystal structures revealed dimeric nectins bound through a stereotyped interface that was previously proposed to represent a cis dimer. However, conservation of this interface and the results of targeted cross-linking experiments showed that this dimer probably represents the adhesive trans interaction. The structure of the dimer provides a simple molecular explanation for the adhesive binding specificity of nectins. Nectin ectodomain structures reveal a canonical adhesive interface.,Harrison OJ, Vendome J, Brasch J, Jin X, Hong S, Katsamba PS, Ahlsen G, Troyanovsky RB, Troyanovsky SM, Honig B, Shapiro L Nat Struct Mol Biol. 2012 Aug 19. doi: 10.1038/nsmb.2366.
