Congratulations to graduate student Ayse Sahan and former student Shawn Mingyuan Chen on the publication of their lipid biosensors in PNAS! With these sensors, we’re able to track PI(3,4)P2 and PIP3 signaling in the cell, and show the lysosome is a PIP3 signaling site. https://www.pnas.org/doi/full/10.1073/pnas.2426929122
