1 Hyperoxia caused rapid activation and redistribution of Rac1, and IQGAP1 to cell periphery, and down-regulation of Rac1, and IQGAP1 attenuated hyperoxia-induced tyrosine phosphorylation of Src and cortactin and ROS generation. Tyrosine IQ motif containing GTPase activating protein 1 Homo sapiens
2 Hyperoxia caused rapid activation and redistribution of Rac1, and IQGAP1 to cell periphery, and down-regulation of Rac1, and IQGAP1 attenuated hyperoxia-induced tyrosine phosphorylation of Src and cortactin and ROS generation. Tyrosine IQ motif containing GTPase activating protein 1 Homo sapiens
3 These results demonstrate a role of PLD in hyperoxia-mediated IQGAP1 activation through Rac1 in tyrosine phosphorylation of Src and cortactin, as well as in p47(phox) translocation and ROS formation in human lung endothelial cells. Tyrosine IQ motif containing GTPase activating protein 1 Homo sapiens
