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 Å resolution. A comparison with the …
