Mutation of the Pleckstrin Homology Domain of Bruton's Tyrosine Kinase in Immunodeficiency Impaired Inositol 1,3,4,5-Tetrakisphosphate Binding Capacity
1 Nov 1996
Abstract excerpt
Bruton's tyrosine kinase (Btk), a cytoplasmic protein-tyrosine kinase, plays a pivotal role in B cell activation and development. Mutations in the pleckstrin homology (PH) domain of the Btk gene cause human X-linked agammaglobulinemia (XLA) and murine X-linked immunodeficiency (Xid). In this paper, we report that the PH domain of Btk functions as an inositol 1,3,4,5-tetrakisphosphate (IP4), inositol...
