Plant phospholipid signaling: “in a nutshell”

Journal of Lipid Research, 2009
Since the discovery of the phosphoinositide/phospholipase C (PI/PLC) system in animal systems, we know that phospholipids are much more then just structural components of biological membranes.

Phosphatidic Acid Accumulates at Areas of Curvature in Tubulated Lipid Bilayers and Liposomes

Biomolecules, 2022
Phosphatidic acid (PA) is a signaling lipid that is produced enzymatically from phosphatidylcholine (PC), lysophosphatidic acid, or diacylglycerol. Compared to PC, PA lacks a choline moiety on the headgroup, making the headgroup smaller than that of PC ...

Methylation of the Gpat2 promoter regulates transient expression during mouse spermatogenesis [PDF]

, 2015
Spermatogenesis is a highly regulated process that involves both mitotic and meiotic divisions, as well as cellular differentiation to yield mature spermatozoa from undifferentiated germinal stem cells.

Lipid Droplet‐Localized Spindle Apparatus Coiled‐Coil Protein 1 Regulates Lipid Droplet Distribution

Advanced Science, EarlyView.
SPDL1‐L, a long isoform of SPDL1, is identified as a bona fide lipid droplet‐associated protein that acts as a dynein adaptor to drive perinuclear clustering of lipid droplets. By linking lipid droplets to the microtubule network, SPDL1‐L extends the function of SPDL1 beyond mitosis and contributes to lipid droplet organization and nuclear remodeling ...

Hydrolysis of long-chain alkyl phosphates and phosphatidic acid by an enzyme purified from pig brain*†

Journal of Lipid Research, 1962
Particulate preparations of rat and pig tissues have been found to catalyze the hydrolysis of lipid phosphates including many alcohol dihydrogen phosphates as well as phosphatidic acids.

The many origins of charge inversion in electrolyte solutions: effects of discrete interfacial charges

, 2007
We show that charge inversion, i.e. interfacial charges attracting counterions in excess of their own nominal charge, is a general effect that takes place in most charged systems next to aqueous solutions with multivalent ions and identify three ...

RASSF4: Regulator of plasma membrane PI(4,5)P2. [PDF]

, 2017
Phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) is a negatively charged phospholipid that plays a major role in recruiting and regulating proteins at the plasma membrane-cytosol interface. In this issue, Chen et al. (2017. J. Cell Biol. https://doi.org/

Identification and Characterization of an In Silico Designed Membrane‐Active Peptide with Antiviral Properties

Advanced Science, EarlyView.
An evolutionary molecular dynamics platform is used to design P1.6, a membrane‐active peptide that senses lipid packing defects in viral envelopes. P1.6 adopts a stabilized α‐helical structure upon membrane contact, disrupts virus‐like liposomes, and damages HIV‐1 particles.

Levels of Arabidopsis thaliana leaf phosphatidic acids, phosphatidylserines, and most trienoate-containing polar lipid molecular species increase during the dark period of the diurnal cycle

Frontiers in Plant Science, 2012
Previous work has demonstrated that plant leaf polar lipid fatty acid composition varies during the diurnal (dark-light) cycle. Fatty acid synthesis occurs primarily during the light, but fatty acid desaturation continues in the absence of light ...

Capping protein modulates the dynamic behavior of actin filaments in response to phosphatidic Acid in Arabidopsis. [PDF]

, 2012
International audienceRemodeling of actin filament arrays in response to biotic and abiotic stimuli is thought to require precise control over the generation and availability of filament ends.
