Function

HEMA_MEASC Attaches the virus to cell receptors and thereby initiating infection. Binding of H protein to the receptor induces a conformational change that allows the F protein to trigger virion/cell membranes fusion. May use human CD46 and/or SLAMF1 as receptors for viral entry into the cell. The high degree of interaction between H and MCP/CD46 results in down-regulation of the latter from the surface of infected cells, rendering them more sensitive to c3b-mediated complement lysis (By similarity).

Publication Abstract from PubMed

Measles virus is a major public health concern worldwide. Three measles virus cell receptors have been identified so far, and the structures of the first two in complex with measles virus hemagglutinin (MV-H) have been reported. Nectin-4 is the most recently identified receptor in epithelial cells, and its binding mode to MV-H remains elusive. In this study, we solved the structure of the membrane-distal domain of human nectin-4 in complex with MV-H. The structure shows that nectin-4 binds the MV-H beta4-beta5 groove exclusively via its N-terminal IgV domain; the contact interface is dominated by hydrophobic interactions. The binding site in MV-H for nectin-4 also overlaps extensively with those of the other two receptors. Finally, a hydrophobic pocket centered in the beta4-beta5 groove is involved in binding to all three identified measles virus receptors, representing a potential target for antiviral drugs.

Defects in PVRL4 are the cause of ectodermal dysplasia-syndactyly syndrome type 1 (EDSS1) [MIM:[http://omim.org/entry/613573 613573]]. EDSS1 is a form of ectodermal dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. EDSS1 is characterized by the association of hair and teeth abnormalities with cutaneous syndactyly of the hands and/or feet. Hair morphologic abnormalities include twists at irregular intervals (pilli torti) and swelling along the shafts, particularly associated with areas of breakage. Dental findings consist of abnormally widely spaced teeth, with peg-shaped and conical crowns. Patients have normal sweating.<ref>PMID:20691405</ref>
