On the linkage of thermodynamics and pathogenicity

Area of Science:

• Biophysics
• Molecular Biology
• Genetics

Background:

• Protein structure and function are crucial for cellular processes.
• Mutations can disrupt protein stability and lead to diseases.
• Thermodynamics plays a key role in protein folding and interactions.

Purpose of the Study:

• To review the impact of disease-causing mutations on protein thermodynamics.
• To analyze the effects of mutations on folding and binding free energy changes.
• To compare the thermodynamic perturbations caused by pathogenic versus benign mutations.

Main Methods:

• Literature review of recent studies.
• Analysis of thermodynamic quantities like folding and binding free energy changes.
• Examination of effects on protein structural dynamics and allosteric pathways.

Main Results:

• Disease-causing mutations, both in monogenic and complex diseases, induce larger thermodynamic perturbations compared to benign mutations.
• Pathogenic mutations significantly affect protein folding and binding free energies.
• Mutations can alter protein structural dynamics and allosteric signaling.

Conclusions:

• Protein thermodynamics is a critical factor in understanding disease mechanisms.
• Quantifying thermodynamic changes caused by mutations can help predict pathogenicity.
• Further research into mutation effects on protein dynamics and allostery is warranted.
