A phosphoinositide signalling pathway mediates rapid lysosomal …
Sep 7, 2022 · Here, using an unbiased proteomic approach, we show that LMP stimulates a phosphoinositide-initiated membrane tethering and lipid transport (PITT) pathway for rapid lysosomal repair.

The PITT pathway: Keeping lysosomes young - Wiley Online Library
The phosphoinositide-initiated membrane tethering and lipid transport (PITT) pathway is essential for rapid lysosomal repair. It is activated by multiple distinct, disease-related lysosome-damaging conditions, suggesting that it is a common mechanism for lysosomal quality control.

Sep 1, 2023 · The PITT pathway rapidly repairs lysosomes by directly transferring lipids to damaged membranes. Multiple pathophysiologically relevant lysosomal-damaging conditions trigger the rapid recruitment of phosphatidylinositol-4 kinase type 2α (PI4K2A) to lysosomes, leading to robust generation of phosphatidylinositol 4-phosphate (PI4P), a lipid ...
