    摘要: The invention provides a computer implemented method of quantifying the quality of packing for a residue comprising one or more residue atoms in a first protein in a first conformation, the method comprising: (a) calculating one or more close contact potentials based on a distance between the one or more residue atoms and one or more environment atoms, (b) calculating a contact area of the one or more residue atoms that is exposed to the one or more environment atoms and (c) calculating a close contact surface density (CCSD) by dividing the sum of the one or more close contact potentials by the contact area.

    摘要: Provided herein are heteromultimer constructs with reduced or silenced effector function. In an embodiment is provided a heteromultimer construct comprising an IgG Fc construct having a first and a second Fc polypeptide, each Fc polypeptide comprising a modified lower hinge region wherein: the modified lower hinge region of said first Fc polypeptide comprises at least one amino acid modification, the modified lower hinge region of said second Fc polypeptide comprises at least one amino acid modification which is different from at least one amino acid modification of said first Fc polypeptide, and the IgG Fc construct displays reduced binding to all Fcγ receptors and to C1q protein as compared to a corresponding parent IgG Fc construct. Also provided are methods of producing such heteromultimer constructs, and methods of reducing ADCC for an antibody construct by reducing effector function.
