  • PubMed Abstract: 

    Bispecific immunoglobulin-like antibodies capable of engaging multiple antigens represent a promising new class of therapeutic agents. Engineering of these molecules requires optimization of the molecular properties of one of the domain components. Here, we present a detailed crystallographic and computational characterization of the stabilization patterns in the lymphotoxin-beta receptor (LTbetaR) binding Fv domain of an anti-LTbetaR/anti-TNF-related apoptosis inducing ligand receptor-2 (TRAIL-R2) bispecific immunoglobulin-like antibody. We further describe a new hierarchical structure-guided approach toward engineering of antibody-like molecules to enhance their thermal and chemical stability.
