IP3/DAG Signaling Pathway

IP3/DAG Signaling Pathway

Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...

Background:

Lipid metabolism is crucial for cellular function.
Investigating lipid metabolism requires effective labeling tools.
Current methods may have limitations in phospholipid synthesis studies.

Purpose of the Study:

To introduce SATE-G3P-N3 as a novel probe for metabolic labeling of glycerolipids (GLs).
To investigate lipid metabolism and phospholipid synthesis in yeast cells.
To assess the utility of the probe for general GL labeling and enhanced phospholipid labeling.

Main Methods:

Metabolic labeling of yeast cells with SATE-G3P-N3.
Cellular fluorescence microscopy for localization studies.
Liquid Chromatography-Mass Spectrometry (LC-MS) for lipid identification.
Thin-Layer Chromatography (TLC) for corroboration of GL labeling.

Main Results:

SATE-G3P-N3 was successfully incorporated into yeast cells.
Probe labeling was observed predominantly at the plasma membrane.
LC-MS confirmed metabolic labeling of various phospholipids (PC, PS, PA, PI, PG) and neutral lipids (MAG, DAG, TAG).
TLC corroborated glycerolipid labeling.

Conclusions:

SATE-G3P-N3 is a versatile tool for metabolic labeling of glycerolipids in yeast.
The probe facilitates general GL labeling and enhanced phospholipid labeling.
SATE-G3P-N3 offers a valuable approach to study lipid metabolism dynamics.
