2 Here, immunoblotting analyses using antibodies against FAK phospho-Tyr 925 and ERK2 phospho-Tyr 204 demonstrated CB1-stimulated FAK 925 Tyr-P and ERK2 204 Tyr-P (0-5 min) which was followed by a decline in Tyr-P (5-20 min). Tyrosine protein tyrosine kinase 2 Homo sapiens

8 The FAK inhibitors Y11 and PF 573228 abolished FAK 925 Tyr-P and partially inhibited ERK2 204 Tyr-P. FAK 925 Tyr-P and ERK2 204 Tyr-P were adhesion-dependent, required an intact actin cytoskeleton, and were mediated by integrins, Flk-1 vascular endothelial growth factor receptors, and epidermal growth factor receptors.

14 FAK 925 Tyr-P and ERK2 204 Tyr-P were blocked by the Gbetagamma inhibitor gallein, a GRK2 inhibitor, and GRK2 siRNA silencing, suggesting Gbetagamma and GRK2 participate in FAK-mediated ERK2 activation. Tyrosine protein tyrosine kinase 2 Homo sapiens
15 FAK 925 Tyr-P and ERK2 204 Tyr-P were blocked by the Gbetagamma inhibitor gallein, a GRK2 inhibitor, and GRK2 siRNA silencing, suggesting Gbetagamma and GRK2 participate in FAK-mediated ERK2 activation. Tyrosine protein tyrosine kinase 2 Homo sapiens
16 Together, these studies indicate FAK 925 Tyr-P occurs concurrently with CB1-stimulated ERK2 activation and requires the actin cytoskeleton and Gi/obetagamma-GRK2-mediated cross-talk between CB1, integrins, and receptor tyrosine kinases (RTKs). Tyrosine protein tyrosine kinase 2 Homo sapiens
