Provided herein is a heavy chain constant region comprising a CH1 domain, a hinge region, a CH2 domain and a CH3 domain, wherein the sequences of said CH1 domain and hinge region derive from the sequences of CH1 domain and hinge region in human IgG2, the sequences of said CH2 domain ...
The preferential susceptibility to proteolysis exhibited by the antibody heavy (H) chain hinge region is a fortuitous aspect of immunoglobulin structure that has had an enormous impact on our ability to study antibody structure. Work on chain separation dates back to the investigations of Petermann an...
A heavy chain constant region, comprising a C<Sub>H</Sub>1 structural domain, a C<Sub>H</Sub>2 structural domain, and a C<Sub>H</Sub>3 structural domain. The sequences of the C<Sub>H</Sub>1 structural domain and a hinge region are derived from the sequences of a C<Sub>H</...
These same threonine residues in the triple-repeat IgG3 hinge region sequences are also the location of the O-linked glycans which occupy ~10% of the six available sites (Supplementary Fig. 1a)8, and were also detected in our IgG3 (Supplementary Fig. 15). Although no O-linked glycans ...
This region serves as the linker between the two Fab arms and the Fc and the upper hinge controls the flexibility and orientations of the Fab arms relative to each other (Fig. 4a)35,36. Unlike the upper hinges of IgG1 or IgG4, the upper hinge of IgG2 has a unique cysteine that ...
Both arms are joined by a flexible hinge region that enables bivalent binding of the antibody with antigen sites at a range of distances. Five different antibody classes or isotypes IgA, IgD, IgE, IgG, and IgM can be found in mammals. Ig classes differ in their sequence, number ...

Fig. 1: Overall structure of EndoS in complex with the Fc region. aEndoS, SpeB and IdeS are secreted enzymes fromS. pyogenesthat can act on IgG antibodies. SpeB and IdeS are proteases that hydrolyze the flexible hinge region between residues 220 to 248 of the IgG antibody96,97,98. En...
According to their research, most of those motifs are located at the lower hinge region and CH2–CH3 interface of Fc. Indeed, the hydrophobic lower hinge (sequence: 231-APELLGGPSVFLFPP-245) is not only the "hot" site for engineering IgG effector function, such as antibody dependent cell ...
The resulting construct has the same SfiI sites as those in pDR-D1 and, even unknown sequences derived from pDR-D1 based library can be directly cloned into pDR-OriP-Fc1. The cloned scFv is designed to be fused to human Fcγ1 through the hinge region which results in Fc-fused dimer...
