- 요약Proteins underpin a vast number of essential functions in the cell. To perform these diverse roles, proteins must fold from a linear chain of amino acids into a three-dimensional structure. Even after reaching this state, proteins repeatedly sample other conformations, where thermodynamics and kinetics determine the probability and rate of each transition. Quantitatively mapping the physical parameters that dictate protein stability is therefore critical to predict how mutations impact function in disease and inform the design of proteins with desired functions. This thesis explores the development and application of approaches to quantify thermodynamic stability at various scales. Beyond thermodynamic stability, kinetic stability is essential for proteins to maintain their native conformation over biologically relevant timescales. Despite this critical role, we lack systematic measurements of protein kinetic stability, which are necessary to understand how changes in sequence impact the abundance and lifetime of proteins. To address this challenge, we introduce SPARKfold (Simultaneous Proteolysis Assay Revealing Kinetics of Folding), a high-throughput microfluidic assay for measuring protein kinetic stability. By studying dihydrofolate reductase (DHFR), we demonstrate that SPARKfold can capture subtle variations in unfolding rates across a wide dynamic range, revealing how changes in protein sequence alter kinetic stability. SPARKfold enables systematic studies of diverse protein systems and variants, providing a powerful tool for uncovering the determinants of kinetic stability. In the future, this versatile platform promises to address both fundamental questions and practical challenges in protein science, from unraveling the role of kinetic stability in cellular function to exploring the design of hyperstable proteins for industrial use. By providing a framework for integrating thermodynamic and kinetic measurements, this work advances our understanding of protein stability while informing future efforts to explore and engineer folding and function.
