Abstract:
Phospholipase D enzymes (PLDs) constitute a family of phosphodiesterases that catalyze the hydrolysis of phosphatidylcholine (PtdCho) to generate choline and phosphatidic acid (PtdOH), a potent lipid signaling molecule implicated in numerous physiological processes. Mammalian PLDs have been localized to multiple organelles, including the nucleus, Golgi apparatus, lysosomes, secretory granules and plasma membrane. However, the detailed mechanisms that govern targeting of PLDs to different organelles, how their local activity is controlled or indeed the nature of PA effectors are not well understood. Here, we discuss recent observations on PLD localization to the Golgi apparatus and how members of this enzyme family might play a role in regulating the structure of this organelle.

Golgi Apparatus
The Golgi apparatus is a eukaryotic organelle that has a distinctive ribbon-like appearance. It is a primary sorting and dispatch station for cargo arriving from the ER. Newly arriving vesicles enter the cis face of the Golgi, closest to the ER, and are...

Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
