Bipartite Genetically Encoded Biosensors to Sense Calcium Ion Dynamics at Membrane-Membrane Contact Sites
Overview
Paper Summary
This paper describes the development and characterization of novel self-complementing, bipartite fluorescent protein-based calcium biosensors. Researchers used these biosensors to visualize changes in calcium concentrations at membrane-membrane contact sites within living cells, specifically at the interface between the endoplasmic reticulum and mitochondria, providing insights into the localized dynamics of calcium signaling.
Explain Like I'm Five
Scientists made new glowing proteins that can be split apart and put back together like LEGOs, and used them to build a sensor that detects calcium flowing between tiny parts of a cell.
