Biochem/physiol Actions

Phosphatidylinositol is a phosphoglyceride, containing inositol as a cyclohexanol head group. The phosphatidylinositol signaling pathway is also called as double signaling pathway as it generates two secondary messengers. It is associated with a number of physiological processes in plants. This includes the development of pollen and vascular organs, root and root hair growth, hormone response and stress tolerance.
Phospholipid membrane component, precursor of inositol phosphates.

Activation of phosphatidylinositol-3-kinase (PI3K) is one of the earliest postreceptor events in the insulin signaling pathway. Incubation of soleus muscles from lean mice with 50 nM insulin caused a 3-10-fold increase in antiphosphotyrosine-immunoprecipitable PI3K (antiPTyr-PI3K) activity within 2 min in

We have measured the distribution of the hexavalent ruthenium red cation (RuR) between water and phospholipid membranes, have shown the critical importance of membrane negative surface charge for RuR binding, and determined the association constant of RuR for different phospholipid

Phosphatidylinositol transfer protein alpha (PITPalpha) selectively transports and promotes exchange of phosphatidylinositol (PI) and phosphatidylcholine (PC) between lipid bilayers. In higher eukaryotes PITPalpha is required for cellular functions such as phospholipase C-mediated signaling, regulated exocytosis, and secretory vesicle formation. We
