WebJul 7, 2024 · Abstract Phosphatidylinositol-3-phosphate (PI3P) is a signaling phospholipid enriched in the membranes of late endosomes (LE) and vacuoles. PI3P mediates vacuolar and endosomal trafficking... WebAfter nucleation, the nascent phagophore is elongated and matured through the action of class III phosphoinositide (PI) 3-kinases, such as vesicular protein sorting 34 (Vps34), which interacts with Beclin-1 (mammalian homologue of yeast Atg6) and harvests phosphatidylinositol-3-phosphate (PI3P) [19].
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. WebFeb 10, 2024 · PI3P is mainly generated by the class III phosphatidylinositol 3-kinase VPS34 through phosphorylation of phosphatidylinositol and has been shown to be essential during the early phase of phagophore biogenesis via recruitment of its effectors DFCP1 (also known as ZFYVE1) and WIPI2 ( Axe et al., 2008; Dooley et al., 2015 ).
