[https://www.uniprot.org/uniprot/IGKC_HUMAN IGKC_HUMAN] Defects in IGKC are the cause of immunoglobulin kappa light chain deficiency (IGKCD) [MIM:[https://omim.org/entry/614102 614102]. IGKCD is a disease characterized by the complete absence of immunoglobulin kappa chains.<ref>PMID:3931219</ref>

The manipulation of protein backbone structure to control interaction and function is a challenge for protein engineering. We integrated computational design with experimental selection for grafting the backbone and side chains of a two-segment HIV gp120 epitope, targeted by the cross-neutralizing antibody b12, onto an unrelated scaffold protein. The final scaffolds bound b12 with high specificity and with affinity similar to that of gp120, and crystallographic analysis of a scaffold bound to b12 revealed high structural mimicry of the gp120-b12 complex structure. The method can be generalized to design other functional proteins through backbone grafting.
