We provide direct evidence that PKCbeta acts as a feedback loop inhibitor of Btk activation. Inhibition of PKCbeta results in a dramatic increase in B-cell receptor (BCR)-mediated Ca2+ signaling. We identified a highly conserved PKCbeta serine phosphorylation site in a short linker within the Tec homology domain of Btk. Mutation of this phosphorylation site led to enhanced tyrosine phosphorylation and membrane association of Btk, and augmented BCR and FcepsilonRI-mediated signaling in B and mast cells, respectively. | This deductive analysis indicated that PKCbeta phosphorylates S180 in the region bisecting the Btk motif (BM) and the PRR of the TH domain. |

PTPRG activation by the P1-WD peptide affected the tyrosine phosphorylation of several signaling molecules. Data analysis identified 31 molecules whose phosphorylation was modified in a statistically significant manner (Table I). inhibition of ABL1, BMX, BTK, DAB1, ITGB1, JAK2, KDR, KIT, LIMK1, MET, PDGFRB, SHC1, and VCL correlates with tyrosine dephosphorylation. In contrast, SRC inhibition correlates with hyperphosphorylation of the inhibitory Tyr530 residue and with dephosphorylation of the activatory Tyr419. Moreover, CDK2 and CTTN inhibition correlates with a hyperphosphorylation of the inhibitory Tyr15 and Tyr470, respectively. In contrast, a subgroup of 13 proteins, including BLNK, DOK2, ERBB2, GRIN2B, INSR, PDGFRA, PRKCD, PXN, STAT1, STAT2, STAT3, STAT5A, and ZAP70, appears to be activated by PTPRG activity. |

Activation of Btk occurs by transphosphorylation of tyrosine 551 in the catalytic domain, resulting in a dramatic increase in the catalytic activity of the kinase (11, 12, 13). This allows for autophosphorylation at tyrosine 223 in the SH3 domain (14). Both Lyn and Syk have been demonstrated to be involved in BCR-mediated Btk activation (11), but processes that drive colocalization of these kinases are ill-defined. Recently, it was suggested that phosphatidylinositol 3-kinase (PI3-K) is also involved in Btk activation |

BTK is a member of the TEC family of non-receptor tyrosine kinases whose deregulation has been implicated in a variety of B-cell-related diseases. We have used structure-based drug design in conjunction with kinome profiling and cellular assays to develop a potent, selective, and irreversible BTK kinase inhibitor, QL47, which covalently modifies Cys481. QL47 inhibits BTK kinase activity with an IC50 of 7 nM, inhibits autophosphorylation of BTK on Tyr223 in cells with an EC50 of 475 nM, and inhibits phosphorylation of a downstream effector PLCγ2 (Tyr759) with an EC50 of 318 nM. |

Activation of Btk occurs by transphosphorylation of tyrosine 551 in the catalytic domain, resulting in a dramatic increase in the catalytic activity of the kinase (11, 12, 13). This allows for autophosphorylation at tyrosine 223 in the SH3 domain (14). Both Lyn and Syk have been demonstrated to be involved in BCR-mediated Btk activation (11), but processes that drive colocalization of these kinases are ill-defined. Recently, it was suggested that phosphatidylinositol 3-kinase (PI3-K) is also involved in Btk activation |

We now describe a protein, bap-135, that is associated with btk in b cells and is a substrate for phosphorylation by btk.Taken together, these observations suggest that bap-135 may reside downstream of btk in a signaling pathway originating at the bcr. |

Phosphorylation of STAT-3 by BTK may also alter the conformation of STAT-3 in such a way as to make it inaccessible as a substrate of activating kinases such as JAK3.|The ability of BTK to negatively regulate STAT-3 activity suggests several possible models for a mechanism of BTK action. |

Our results indicate that Gq-mediated activation of Btk is necessary for stimulation of p38 kinase by Gq-coupled receptors in DT40 lymphoma cells. Hence, stimulation of Btk kinase by Gaq may be essential in vivo for activation of p38 kinase. |
