Bruton tyrosine kinase (BTK) in X-linked agammaglobulinemia (XLA).
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, Bmx and Txk belong to a distinct family of protein kinases. These prote...
متن کاملBTK (Bruton agammaglobulinemia tyrosine kinase)
The BTK protein is a 77 kDa protein of 659 amino acids. Translation of the BTK transcript starts at the ATG site that is located in exon 2 and ends in exon 19. The BTK protein is composed of an N-terminal Pleckstrin homology (PH) domain followed three protein interacting domains: Tec homology (TH) region, Src homology 3 (SH3) domain and SH2 domain. A tyrosine-kinase catalytic domain is located ...

متن کاملFemale agammaglobulinemia due to the Bruton tyrosine kinase deficiency caused by extremely skewed X-chromosome inactivation.
We analyzed the cause of agammaglobulinemia in a girl whose father had been diagnosed as having X-linked agammaglobulinemia (XLA). Flow cytometric analysis revealed the lack of peripheral B cells with the block of B-cell differentiation in the stages between pro-B cells and pre-B cells in the bone marrow, and the defect of the Bruton tyrosine kinase (BTK) expression on monocytes. We found a BTK...
