Lu Shan et al. present a structure-guided approach to engineer a monovalent form of the fragment crystallizable (Fc) region of an IgG4 antibody to adapt multiple versions of half-life extension modifications and bispecific targeting. Additionally, they report co-crystal structures of the variants bound to the Fc neonatal receptor that allow insights into the binding interactions.
