Escape calculator update illustrates pleiotropic constraints on SARS-CoV-2 RBD evolution
I've updated the SARS-CoV-2 RBD antibody escape calculator with new yeast-display deep mutational scanning data from Yunlong Cao's group. My interpretation: the antigenic evolution of the RBD is currently constrained by the pleiotropic effects of mutations on 1:1 RBD-ACE2 affinity, up-down RBD positioning in the context of full spike, and antibody neutralization.
