: The protein G3BP (GTPase-activating protein-binding protein) acts as a central "node" or switch for granule formation.
is a supplemental video file from a high-profile scientific study titled "RNA-Induced Conformational Switching and Clustering of G3BP Drive Stress Granule Assembly by Condensation," published in the journal Cell in April 2020. Scientific Context g8046.mp4
, showing purified G3BP and RNA forming droplets in a controlled laboratory setting. of stress granules forming in living HeLa cells
of stress granules forming in living HeLa cells. This leads to the formation of liquid-like droplets
This research is significant because it explains how cells quickly organize their internal machinery to survive harsh conditions, a process linked to neurodegenerative diseases when it goes awry.
: When the cell is stressed, unfolded RNA molecules bind to G3BP, causing it to expand and cluster together. This leads to the formation of liquid-like droplets (condensates) that sequester mRNA. Usage in the Study
As part of the supplemental material for this research, the video likely demonstrates one of the following:
