Multiple Amino Acid Substitutions in Hemagglutinin Are Necessary for Wild-Type MeaslesVirus To Acquire the Ability To Use Receptor CD46 Efficiently
21 Dec 2006
Abstract excerpt
Measles virus (MV) possesses two envelope glycoproteins, namely, the receptor-binding hemagglutinin (H) and fusion proteins. Wild-type MV strains isolated in B-lymphoid cell lines use signaling lymphocyte activation molecule (SLAM), but not CD46, as a cellular receptor, whereas MV vaccine strains of the Edmonston lineage use both SLAM and CD46 as receptors. Studies have shown that the residue at position 481 of...
