== Disease ==
[https://www.uniprot.org/uniprot/IGHG1_HUMAN IGHG1_HUMAN] Defects in IGHG1 are a cause of multiple myeloma (MM) [MIM:[https://omim.org/entry/254500 254500]. MM is a malignant tumor of plasma cells usually arising in the bone marrow and characterized by diffuse involvement of the skeletal system, hyperglobulinemia, Bence-Jones proteinuria and anemia. Complications of multiple myeloma are bone pain, hypercalcemia, renal failure and spinal cord compression. The aberrant antibodies that are produced lead to impaired humoral immunity and patients have a high prevalence of infection. Amyloidosis may develop in some patients. Multiple myeloma is part of a spectrum of diseases ranging from monoclonal gammopathy of unknown significance (MGUS) to plasma cell leukemia. Note=A chromosomal aberration involving IGHG1 is found in multiple myeloma. Translocation t(11;14)(q13;q32) with the IgH locus. Translocation t(11;14)(q13;q32) with CCND1; translocation t(4;14)(p16.3;q32.3) with FGFR3; translocation t(6;14)(p25;q32) with IRF4.

== Publication Abstract from PubMed ==
The well-studied B-domain from Staphylococcal protein A is a 59 amino acid three-helix bundle that binds the Fc portion of IgG with a dissociation constant of ~35 nM. The B-domain variant bearing a Gly to Ala mutation (=Z-domain) has been the subject of efforts to minimize a domain's size while retaining its function. We report X-ray crystallographic characterization of three steps in such a process using complexes with Fc: the full three-helix Z-domain, a 34 amino acid two-helix version called Z34C and a 13 amino acid single helix stabilized with an exo-helix tether, called LH1.
