Anti-Phospho-BTK: Rabbit Brutons Tyrosine Kinase, Phospho-Tyr223 Antibody |
 |
BACKGROUND Bruton's Tyrosine Kinase (BTK) is member of the Tec family that is critically important for the growth, differentiation and activation of myeloid-, mast- and B-cells.1 BTK is activated firstly by membrane localization stimulated by PIP3 generation, and subsequently, by transphosphorylation of Tyr-551 by Src family kinases. Further activation occurs within the SH3 domain via a transphosphorylation mechanism. Tyr223 in this domain was phosphorylated by c-Abl.2 Activated BTK is involved in the phosphorylation of a number of signaling molecules involved in the PLCgamma, JNK and p38 MAPK pathways, leading to Ca2+ mobilization, mRNA stabilization and the induction of NF-kappaB and AP-1 transcription factors.3 BTK activity is negatively regulated by a number of proteins including inhibitor of BTK (IBTK), Sab and c-Cbl. Mutations in this enzyme are known in humans and result in the immunological disorder X-linked agammaglobulemia.4
