Structure of the PH domain and Btk motif from Bruton's tyrosine kinase: molecular explanations for X-linked agammaglobulinaemia.
Bruton's tyrosine kinase (Btk) is an enzyme which is involved in maturation of B cells. It is a target for mutations causing X-linked agammaglobulinaemia (XLA) in man. We have determined the structure of the N-terminal part of Btk by X-ray crystallography at 1.6 A resolution. This part of the kinase contains a pleckstrin homology (PH) domain and a Btk motif. The structure of the PH domain is si...
متن کاملBTK, the tyrosine kinase affected in X-linked agammaglobulinemia.
X-linked agammaglobulinemia (XLA) is a heritable immunodeficiency disorder that is caused by a differentiation block leading to almost complete absence of B lymphocytes and plasma cells. The affected protein is a cytoplasmic protein tyrosine kinase, Bruton's agammaglobulinemia tyrosine kinase (Btk). Btk along with Tec, Itk and Bmx belong to a distinct family of protein kinases. These proteins c...

متن کامل"screening of the bruton tyrosine kinase (btk) gene mutations in 13 iranian patients with presumed x-linked agammaglobulinemia "
x-linked agammaglobulinemia (xla) is an immunodeficiency caused by mutations in the bruton tyrosine kinase (btk) gene. in order to identify the mutations in btk gene in iranian patients with antibody deficiency, 13 male patients with an xla phenotype from 11 unrelated families were enrolled as the subjects of investigation for btk mutation analysis using pcr-sscp followed by sequencing. five di...
متن کاملIdentification of novel Bruton's tyrosine kinase mutations in 10 unrelated subjects with X linked agammaglobulinaemia.
Mutations of the Bruton's tyrosine kinase (Btk) gene cause X linked agammaglobulinaemia (XLA). This inherited immunodeficiency disease causes an arrest in B cell differentiation of pre-B cells to mature B cells. In this study we report the characterisation of mutations in the Btk gene in 10 unrelated XLA families. The screening approach we used was based on reverse transcriptase PCR and direct ...
