Btk mutation
Did you know?
The Btk gene is located on the X chromosome (Xq21.3-q22). At least 400 mutations of the BTK gene have been identified. Of these, at least 212 are considered to be disease-causing mutations. BTK inhibitors. Approved drugs that inhibit BTK: Ibrutinib (Imbruvica), a selective Bruton's tyrosine kinase inhibitor. See more Bruton's tyrosine kinase (abbreviated Btk or BTK), also known as tyrosine-protein kinase BTK, is a tyrosine kinase that is encoded by the BTK gene in humans. BTK plays a crucial role in B cell development. See more BTK contains five different protein interaction domains. These domains include an amino terminal pleckstrin homology (PH) domain, a proline-rich TEC homology (TH) … See more Mutations in the BTK gene are implicated in the primary immunodeficiency disease X-linked agammaglobulinemia (Bruton's agammaglobulinemia); sometimes abbreviated to XLA and selective IgM deficiency.

See more Bruton's tyrosine kinase has been shown to interact with: • ARID3A • BLNK (SLP-65), • CAV1, See more Web28 Oct 2024 · BTK is predominantly expressed in hematopoietic cells ( 4, 5 ). In B lymphocytes, BTK is primarily required for B cell receptor (BCR) signaling ( 2, 3, 6 ). Upon BCR activation, BTK is recruited to the BCR signaling complex, where Btk activity is positively regulated by phosphorylation events.

XLA patients experience a blockage on B-cell development in the bone marrow, which, in severely affected patients, leads to little/no functional serum immunoglobulins and therefore increased disease susceptibility [ 2, 3] (Figure 1 ).
