Analysis of receptor (CD46, CD150) usage by measles virus

J Gen Virol. 2002 Jun;83(Pt 6):1431-1436. doi: 10.1099/0022-1317-83-6-1431.

Abstract

In order to investigate which measles virus (MV)-strains use CD46 and/or CD150 (signalling lymphocytic activation molecule, SLAM) as receptors, CHO cells expressing either recombinant CD46 or SLAM were infected with a panel of 28 MV-strains including vaccine strains, wild-type strains with various passage histories and recombinant viruses. We found that SLAM served as a common receptor conferring virus uptake and syncytium formation for all MV-strains tested. Predominantly vaccine and laboratory adapted strains, but also a minor fraction of the wild-type strains tested, could utilize both CD46 and SLAM. Using recombinant viruses, we demonstrate that the single amino acid exchange in the haemagglutinin (H) protein at position 481 Asn/Tyr (H481NY) determines whether the virus can utilize CD46. This amino acid alteration has no affect on the usage of SLAM as receptor, and as such demonstrates that the binding sites for SLAM and CD46 are distinct.
