Potential structure/function relationships of predicted secondary structural elements of tau.

Area of Science:

• Neuroscience
• Biochemistry
• Structural Biology

Background:

• Microtubule-associated protein tau is typically considered natively unfolded.
• Tau protein self-associates into filamentous structures in neurodegenerative diseases.
• These tau filaments exhibit ordered structures, suggesting underlying secondary and higher-order structures.

Purpose of the Study:

• To identify potential secondary structural elements in tau.
• To investigate the role of these elements in tau's normal and pathological functions.
• To enhance understanding of tau structure-function relationships.

Main Methods:

• Analysis of the primary amino acid sequence of tau.
• Application of predictive computational methods for protein structure identification.

Main Results:

• Few, but specific, potential secondary structural elements were predicted in the tau molecule.
• These predicted elements offer insights into how tau might form ordered structures.

Conclusions:

• Despite being largely unfolded, tau likely possesses secondary structures crucial for its function and aggregation.
• Predictive analyses provide a foundation for understanding tau's structural basis in health and disease.
