Description:
Mice that bear the X-linked immunodeficiency (xid) mutation have a B lymphocyte-specific defect resulting in an inability to make antibody responses to polysaccharide antigens. A backcross of 1114 progeny revealed the colocalization of xid with Bruton's agammaglobulinemia tyrosine kinase (btk) gene, which is implicated in the human immune deficiency, X-linked agammaglobulinemia. Mice that carry xid have a missense mutation that alters a highly conserved arginine near the amino-terminus of the btk protein, Btk. Because this region of Btk lies outside any obvious kinase domain, the xid mutation may define another aspect of tyrosine kinase function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thomas, J D -- Sideras, P -- Smith, C I -- Vorechovsky, I -- Chapman, V -- Paul, W E -- GM33160/GM/NIGMS NIH HHS/ -- HG00277/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1993 Jul 16;261(5119):355-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8332900" target="_blank"〉PubMed〈/a〉
