Summary
Functional fluctuation, not just structural, is vital for understanding biological systems. This concept is supported by experiments in neuro-immune crosstalk, gene transfection, and stem cell signaling.
Area of Science:
- Biochemistry and life sciences
- Molecular and structural biology
Context:
- Protein conformation dictates biological function, but structures are dynamic, not rigid.
- Structural fluctuations in biomacromolecules are recognized as important.
- The concept of 'functional fluctuation' remains underexplored in biological systems.
Purpose:
- To propose and explore the significance of 'functional fluctuation' in biological systems.
- To highlight the importance of dynamic molecular behavior beyond static structure.
- To provide experimental evidence supporting the role of functional fluctuation.
Summary:
- This review introduces the concept of functional fluctuation as a critical factor in biological processes.
- It argues that understanding dynamic molecular behavior is essential for comprehending supramolecular mechanisms, cellular processes, and system interactions.
- Recent experimental findings in neuro-immune crosstalk, gene transfection, and embryonic stem cell signaling support this new theme.
Impact:
- Broadens the understanding of biological mechanisms by incorporating dynamic functional aspects.
- Provides a new framework for investigating molecular interactions and cellular processes.
- Encourages further research into the role of fluctuation in diverse biological systems and diseases.
