Organizing biochemistry in space and time using prion-like self-assembly

Area of Science:

• Biochemistry
• Molecular Biology
• Systems Biology

Background:

• Prion-like proteins exhibit conformational plasticity, enabling self-propagation and templating.
• While linked to disease, these proteins also regulate normal cellular functions.

Purpose of the Study:

• To explore the dual role of prion-like proteins in disease and normal biological organization.
• To highlight the potential of prion-like mechanisms in biotechnology and therapeutics.

Main Methods:

• Review of existing literature on prion-like protein behavior.
• Analysis of prion-like mechanisms across different organisms.
• Conceptual framework for understanding prion-like systems.

Main Results:

• Prion-like proteins are utilized by organisms from bacteria to mammals for proteome organization.
• These proteins function as 'protein-based genes,' facilitating heritable traits.
• Prion-like behavior offers an economical system-level control of biochemistry and gene regulation.

Conclusions:

• Prion-like mechanisms are fundamental to biological processes and gene regulation.
• Harnessing prion-like behavior presents a novel strategy for combating diseases.
• Understanding prion-like proteins is key for developing engineered biological systems.
