    Bruton's tyrosine kinase is intimately involved in signal transduction pathways regulating survival, activation, proliferation, and differentiation of B lineage lymphoid cells. Mutations in the human btk gene are the cause of X-linked agammaglobulinemia, a male immune deficiency disorder characterized by a lack of mature, immunoglobulin-producing B lymphocytes. We have determined the x-ray crystal structure of the Bruton's tyrosine kinase kinase domain in its unphosphorylated state to a 2.1 A resolution. A comparison with the structures of other tyrosine kinases and a possible mechanism of activation unique to Bruton's tyrosine kinase are provided.
