Crystal Structures of the Plant Phospholipase A1 Proteins Reveal a Unique Dimerization Domain
Phospholipase is an enzyme that hydrolyzes various phospholipid substrates at specific ester bonds and plays important roles such as membrane remodeling, as digestive enzymes, and the regulation of cellular mechanism.

Phospholipase C isozymes as effectors of Ras superfamily GTPases
The physiological effects of many extracellular stimuli are initiated through receptor-promoted activation of phospholipase C and inositol lipid signaling pathways.

Lipid levels in sperm, eggs, and during fertilization in Xenopus laevis
Critical developmental periods, such as fertilization, involve metabolic activation, membrane fusion events such as sperm-egg or plasma membrane-cortical granule merger, and production and hydrolysis of phospholipids.

Current data on the effectiveness of gliclazide and molecular mechanisms of action of the drug
With the growing prevalence of type 2 diabetes mellitus (T2DM) the possibility of treating it with available drugs is one of the main issues. Although glycemic control and reduction of micro- and macrovascular outcomes remain important aspects of ...

Activation of phospholipase D-2 by P2X7 agonists in rat submandibular gland acini
Exogenous ATP stimulated phospholipase D (PLD), but not sphingomyelinase in rat submandibular gland (SMG) acini. PLD activation was dependent upon extracellular Ca2+ and did not involve intracellular Ca2+ mobilization or phosphoinositide-specific ...

Lipid vesicle fusion induced by phospholipase C activity in model bile.
Using a system of phosphatidylcholine-cholesterol vesicles to model the vesicle phase of mammalian bile (1:1 molar ratio) we evaluated whether very small amounts of C.
