Visualizing PINK1 Activity Dynamics in Single Cells with a Phase Separation-Based Kinase Activity Reporter

Katie G. Vineall, Alexia Andrikopoulos, Michael Sun…·Danielle L. Schmitt

This paper develops a phase separation-based PINK1 biosensor to visualize real-time PINK1 activity in single live cells and study its role in mitophagy.

LKB1 Spatially Regulates AMPK Activity Coordinate Cellular Oxidative Stress Response

Kasey Parks, Arnav Jhawar, Alexia Andrikopoulos…·Danielle L. Schmitt

This study shows that LKB1 spatially regulates AMPK activity in response to oxidative stress, affecting metabolic and gene expression changes, and identifies impaired LKB1-AMPK signaling in certain cancers.
