WebPI (3)P diC8 (Phosphatidylinositol 3-phosphate diC8) is a synthetic, purified dioctanoyl PI (3)P. Phosphoinositides (PIPns) are minor components of cellular membranes but are integral signaling molecules for cellular communication. Phosphatidylinositol 3-phosphate is enriched in early endosomes having roles in endosome fusion and receptor ... WebPI (3)P is highly enriched in early endosomes, intralumenal vesicles of MVEs and yeast vacuoles ( Gillooly et al., 2000) and has been shown to play a role in autophagy ( Yang and Klionsky, 2010 ). The function of PI (3)P is tightly linked to its effector proteins that bind the lipid via specific binding domains. WebSep 30, 2024 · Phosphatidylinositol 3-phosphate (PI3P) is an essential membrane signature for both autophagy and endosomal sorting that is synthesized in plants by the class III phosphatidylinositol 3-kinase (PI3K) complex, consisting of the VPS34 kinase, together with ATG6, VPS15, and either VPS38 or ATG14 as the fourth subunit. chilly\u0027s coffee mug
