1 GTP-dependent interaction between phospholipase D and dynamin modulates fibronectin-induced cell spreading. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
2 Dynamin as a PLD-interacting partner is a large GTP binding protein that has been considered a mechanochemical enzyme involved in endocytosis by hydrolyzing GTP. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
3 Dynamin as a PLD-interacting partner is a large GTP binding protein that has been considered a mechanochemical enzyme involved in endocytosis by hydrolyzing GTP. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
4 Here, we demonstrate that PLD can be regulated by dynamin in a GTP-dependent manner and that this is critical for FN-mediated cell spreading. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
5 Moreover, PLD interacted with dynamin in a GTP-dependent manner in FN signaling, and this interaction was crucial for FN-induced PLD activation and cell spreading. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
6 Moreover, PLD interacted with dynamin in a GTP-dependent manner in FN signaling, and this interaction was crucial for FN-induced PLD activation and cell spreading. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
7 Also, we found that PLD mutant (R128K) that didn"t have GAP activity increased the GTP-dependent interaction between PLD and dynamin; it also increased PLD activity and cell spreading. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
8 Also, we found that PLD mutant (R128K) that didn"t have GAP activity increased the GTP-dependent interaction between PLD and dynamin; it also increased PLD activity and cell spreading. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
9 Also, we found that PLD mutant (R128K) that didn"t have GAP activity increased the GTP-dependent interaction between PLD and dynamin; it also increased PLD activity and cell spreading. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
10 These results imply that GTP-loaded dynamin, like a small GTPase could mediate a "switch on" signaling via interaction with PLD that has a role as an effector. Guanosine Triphosphate glycosylphosphatidylinositol specific phospholipase D1 Homo sapiens
