Group V Secreted Phospholipase A2 Induces the Release of Proangiogenic and Antiangiogenic Factors by Human Neutrophils [PDF]
, 2017 Secreted phospholipases A2 (sPLA2s) are extracellular enzymes that catalyze the release of free fatty acids and lysophospholipids from membrane phospholipids and also bind to different receptors (e.g., PLA2R1 or integrins).

Differentiation of phospholipases A in mitochondria and lysosomes of rat liver
Journal of Lipid Research, 1969 Highly purified mitochondria from rat liver contain a phospholipase A that catalyzes removal of 2-fatty acids, with a pH optimum above pH 8.0. Lysosomal preparations appeared to have two phospholipases A associated with them, one with a pH optimum at ...

Calcium-independent phospholipases A2 and their roles in biological processes and diseases
Journal of Lipid Research, 2015 Among the family of phospholipases A2 (PLA2s) are the Ca2+-independent PLA2s (iPLA2s) and they are designated group VI iPLA2s. In relation to secretory and cytosolic PLA2s, the iPLA2s are more recently described and details of their expression and roles ...

Signalling Pinpointed to the Tip: The Complex Regulatory Network That Allows Pollen Tube Growth
Plants, 2020 Plants display a complex life cycle, alternating between haploid and diploid generations. During fertilisation, the haploid sperm cells are delivered to the female gametophyte by pollen tubes, specialised structures elongating by tip growth, which is ...

Low-level laser therapy decreases local effects induced by myotoxins isolated from Bothrops jararacussu snake venom [PDF]
, 2010 The prominent myotoxic effects induced by Bothrops jararacussu crude venom are due, in part, to its polycationic myotoxins, BthTX-I and BthTX-II. Both myotoxins have a phospholipase A2 structure: BthTX-II is an active enzyme Asp-49 PLA2, while BthTX-I is

Proteome and Peptidome of Vipera berus berus Venom
Molecules, 2016 Snake venom is a rich source of peptides and proteins with a wide range of actions. Many of the venom components are currently being tested for their usefulness in the treatment of many diseases ranging from neurological and cardiovascular to cancer.
