... constituents of cells as well as signals, and phospholipid-modifying enzymes are well known effectors of small GTPases. We have shown that PLDs (phospholipases D) and their product, PA (phosphatidic acid), belong to the regulators of the secretory pathway in plants. We have also shown that specific NOXs (NADPH...

..., but not PC, between distinct membrane bilayer systems in vitro . Further analysis reveals that SFH proteins functionally interact with the Stt4p phosphoinositide 4-kinase to stimulate PtdIns(4,5) P 2 synthesis which in turn activates phospholipase D. Finally, genetic analyses indicate that Sfh5p interfaces...

...Z. Novotna; O. Valentova; J. Martinec; T. Feltl; K. Nokhrina Different forms of phospholipase D (dependent on and independent of the presence of phospha-tidylinositol 4,5-bisphosphate, PIP 2 ) were identified in maturing and germinating seeds of Brassica napus. Both forms were present in cytosolic...
