Phosphatidylinositol 4,5-bisphosphate or PtdIns (4,5)P2, also known simply as PIP2 or PI (4,5)P2, is a minor phospholipid component of cell membranes. PtdIns (4,5) P2 is enriched at the plasma membrane where it is a substrate for a number of important signaling proteins. [1] . PIP2 also forms lipid clusters [2] that sort proteins. [3][4][5]

2023年8月24日 · Phosphatidylinositol 4,5-bisphosphate (PIP2) is an essential lipid involved in metabolic processes. It is integral to the cell membrane of all animal and plant cells and acts as a second...

2020年11月6日 · In this review, we focus on past and recent exciting results on different molecular mechanisms that regulate cellular functions by binding of specific proteins to PIP2 or by stabilizing phosphoinositide pools in different cellular compartments.

PIP2 domains [1] (also called PIP2 clusters) are a type of cholesterol-independent lipid domain formed from phosphatidylinositol and positively charged proteins in the plasma membrane. [2] [3] They tend to inhibit GM1 lipid raft function. [4]

Amongst its many functions, PIP2 is a substrate for Phospholipase C-coupled G-protein pathways involved in intracellular calcium release in a number of tissues and is also a substrate for class I phosphoinositide 3-kinase (PI3-K).

2022年11月11日 · In the almost 70 years since the first hints of its existence, the phosphoinositide, phosphatidyl-D- myo -inositol 4,5-bisphosphate has been found to be central in the biological regulation of plasma membrane (PM) function.
