Deep mutational scanning of rabies glycoprotein defines mutational constraint and antibody-escape mutations.

Abstract excerpt

Rabies virus causes nearly 60,000 human deaths annually. Antibodies that target the rabies glycoprotein (G) are being developed as post-exposure prophylactics, but mutations in G can render such antibodies ineffective. Here, we use pseudovirus deep mutational scanning to measure how all single-amino-acid mutations to G affect cell entry and neutralization by a panel of antibodies. These measurements identify...
