CD46 is a cellular receptor for bovine viral diarrhea virus.

ABSTRACT: Various monoclonal antibodies (MAbs) that recognize cell surface proteins on bovine cells were previously shown to efficiently block infection with bovine viral diarrhea virus (BVDV) (C. Schelp, I. Greiser-Wilke, G. Wolf, M. Beer, V. Moennig, and B. Liess, Arch. Virol. 140:1997-2009, 1995). With one of these MAbs, a 50- to 58-kDa protein was purified from calf thymus by immunoaffinity chromatography. Microchemical analysis of two internal peptides revealed significant sequence homology to porcine and human CD46. The cDNA of bovine CD46 (CD46(bov)) was cloned and further characterized. Heterologously expressed CD46(bov) was detected by the MAb used for purification. A putative function of CD46(bov) as a BVDV receptor was studied with respect to virus binding and susceptibility of nonpermiss
