Btk

Bruton tyrosine kinase (Btk) is a member of the Tec family kinases with a well-characterized role in B-cell antigen receptor (BCR)-signaling and B-cell activation.Btk is a new target for diseases with abnormal B cell activity because it is essential for B cell development and activation through the BCR signaling pathway. The human primary immune deficiency disease X-linked agammaglobulinemia (XLA), which is caused by a mutation in the Btk gene, highlights the importance of Btk, a kinase that is only expressed in B cells and myeloid cells. The BCR signaling pathway depends on Btk in many ways.B cell receptor oligomerization, Syk and Lyn kinase activation, and Btk kinase activation are all caused by antigen binding to the BCR. When Btk is activated, it joins forces with proteins like BLNK, Lyn, and Syk to form a signaling complex that phosphorylates phospholipase C (PLC)2. This results in transcriptional changes that promote B cell survival, proliferation, and/or differentiation by releasing intracellular Ca2+ stores downstream and propagating the BCR signaling pathway through extracellular signal-regulated kinase and NF-B signaling.
