General description
18:1 PI(5)P (1,2-dioleoyl-sn-glycero-3-phospho-(1′-myo-inositol-4′-phosphate) is an ammonium salt of modified lipid which bears a double at the 9th carbon of dioleoyl group. Phosphatidylinositol 4-phosphate (PI-4-P) is an abundant phosphoinositide species present in the plasma membrane.
Inositol phospholipid species are membrane-bound signaling molecules that have been implicated in almost all aspects of cellular physiology, including cellular growth, metabolism, proliferation, and survival.
Application
18:1 PI(5)P (1,2-dioleoyl-sn-glycero-3-phospho-(1′-myo-inositol-4′-phosphate) (ammonium salt)) has been used in protein−lipid overlay assay. It may be used in small unilamellar vesicles for liposome flotation assays. It may also be used in different lipid binding specificity studies.
Biochem/physiol Actions
Phosphatidylinositol 4-phosphate (PI-4-P) is an important factor, that is required for membrane traffic, polarized growth and cytoskeleton organization.

The phospholipid phosphatidylinositol-4-phosphate [PI(4)P], generated at the Golgi and plasma membrane, has been implicated in many processes, including membrane traffic, yet its role in cell morphology changes, such as the budding to filamentous growth transition, is unknown. We show that

Phosphoinositides function as lipid signals in plant development and stress tolerance by binding with partner proteins. We previously reported that Arabidopsis (Arabidopsis thaliana) phosphoinositide-specific phospholipase C2 functions in the endoplasmic reticulum (ER) stress response. However, the underlying molecular mechanisms of

To reduce costs of lipid-binding assays, allow for multiple lipids to be screened for protein binding simultaneously, and to make lipid binding more user friendly, lipids have been dotted onto membranes to investigate lipid-protein interactions. These assays are similar to

While the majority of phosphatidylinositol-4, 5-bisphosphate (PI-4, 5-P2) in mammalian cells is generated by the conversion of phosphatidylinositol-4-phosphate (PI-4-P) to PI-4, 5-P2, a small fraction can be made by phosphorylating phosphatidylinositol-5-phosphate (PI-5-P). The physiological relevance of this second pathway is

Macropinocytosis, the internalization of extracellular fluid and material by plasma membrane ruffles, is critical for antigen presentation, cell metabolism, and signaling. Macropinosomes mature through homotypic and heterotypic fusion with endosomes and ultimately merge with lysosomes. The molecular underpinnings of this
