Biology and Physics of Stress-Induced mRNP Condensation

Explore the biological and physical mechanisms underlying stress-induced mRNP condensation in this 47-minute conference talk from the Kavli Institute for Theoretical Physics. Delve into how living cells coordinate molecular activities through membrane-less compartments called biomolecular condensates, which play crucial roles in gene expression, signal transduction, and neurotransmission. Examine the diverse properties of these condensates including their lifetimes, sizes, mechanochemical characteristics, and architectures. Learn about current theoretical frameworks and simulation approaches for describing biomolecular condensates, while discovering new experimental methods for characterizing their functions. Investigate the physicochemical principles that shape condensate formation and understand the challenges in mapping computational and laboratory models to actual cellular condensates. Gain insights into how the emergent physical properties of condensates mediate their biological functions, a key structure-function relationship that remains poorly understood in the field. This presentation is part of a broader conference aimed at building cross-disciplinary bridges between theorists and experimentalists working on biomolecular condensates.
