Western equine encephalitis virus (WEEV) strains exhibit different patterns of engagement for two of their entry receptors: very-low-density lipoprotein receptor (VLDLR) and protocadherin 10 (PCDH10). Using structural and functional studies, we show that while all WEEV strains have a lipoprotein class A (LA) domain binding site near the E1 fusion loop, VLDLR engagement requires a second binding site in E2 that can vary with single nucleotide substitutions. We also resolve a structure of PCDH10 bound to WEEV, which reveals interactions near the E1 fusion loop with residues that also mediate LA domain binding. Evolutionary analysis enabled the generation of a PCDH10 decoy that protects in vivo against all WEEV strains tested. Our experiments demonstrate how viruses can engage multiple receptors using shared determinants, which likely impacts cellular tropism and virulence. | |||||||||
