Abstact

Mammalian orthoreoviruses use glycans and junctional adhesion molecule A (JAM-A) as attachment receptors. We determined the structure of serotype 1 reovirus attachment protein σ1 alone and in complex with JAM-A. Comparison with the structure of serotype 3 reovirus σ1 bound to JAM-A reveals that both σ1 proteins engage JAM-A with similar affinities and via conserved binding epitopes. Thus, σ1-JAM-A interactions are unlikely to explain the differences in pathogenesis displayed by these reovirus serotypes.
