Correlation of N-glycan dynamics and interaction network with allosteric antigen binding and Fc receptor recognition

open access: yesExploration of Immunology, 2021
Aim: Fragment crystallizable (Fc) glycans modulate Fc conformations and functions, and glycan may also regulate antigen recognition. In the antibody drug development, glycosylation patterns affect antibody drug characteristics and quality control.
