|UniProt annotation for PVRL4_HUMAN » Poliovirus receptor-related protein 4|
|FUNCTION: Seems to be involved in cell adhesion through trans- homophilic and -heterophilic interactions, the latter including specifically interactions with PVRL2/nectin-1. Does not act as receptor for alpha-herpesvirus entry into cells. SUBUNIT: Self-associates. Interacts via its Ig-like V-type domain with PVRL1/nectin-1 Ig-like V-type domain. Interacts via its C- terminus with MLLT4. Binds to Measles virus protein H and acts as a receptor for this virus. TISSUE SPECIFICITY: Predominantly expressed in placenta. Not detected in normal breast epithelium but expressed in breast carcinoma. DISEASE: Ectodermal dysplasia-syndactyly syndrome 1 (EDSS1) OMIM: 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. mutations affecting the gene represented in this entry.|
