1 In T lymphocytes, Ras can be activated by two Ras exchange factors, SOS and RasGRP1, which are recruited through the adapters Grb2 and LAT and via the second-messenger diacylglycerol (DAG), respectively. Diglycerides RAS guanyl releasing protein 1 Homo sapiens
2 In T lymphocytes, Ras can be activated by two Ras exchange factors, SOS and RasGRP1, which are recruited through the adapters Grb2 and LAT and via the second-messenger diacylglycerol (DAG), respectively. Diglycerides RAS guanyl releasing protein 1 Homo sapiens
3 RasGRP1 relies on its DAG-binding domain to selectively activate Erk kinases. Diglycerides RAS guanyl releasing protein 1 Homo sapiens
4 Activation of Erk correlates with the phosphorylation of threonine residue 184 in RasGRP1. Threonine RAS guanyl releasing protein 1 Homo sapiens
5 Last, DAG-PKC-RasGRP1-driven Ras-Erk activation in T cells is a unique signaling event, not simply compensated for by SOS activity. Diglycerides RAS guanyl releasing protein 1 Homo sapiens
