From Lipid Dynamics to Precision Predictions: A New Approach Methodology for Precision Modeling of Phosphoinositide Signaling

Gonzalo Hernandez-Hernandez, Mindy Tieu, Pei‐Chi Yang…·Colleen E. Clancy

This paper develops a new methodology to model phosphoinositide signaling dynamics, showing that basal PI(4)P levels determine cell-specific responses to genetic perturbations.
