Multiplexed imaging of G-proteins and ERK activity upon activation of CaSR

Sergei Chavez-Abiega, Luca Bordes, Marten Postma…·Joachim Goedhart

The paper develops a method to track G-protein and ERK activities in single cells using biosensors but finds challenges in obtaining robust FRET measurements.

Biosensor imaging of G protein mediated Signaling Pathways Activated Immediately Downstream of CaSR

Sergei Chavez-Abiega, Frank J. Bruggeman, Joachim Goedhart

The paper uses biosensors to study CaSR-mediated signaling pathways in HEK-293 cells, showing activation of Gq and Gi proteins and their effects on intracellular calcium and cAMP levels.
