AI Article Synopsis

  • Biomolecular condensates play crucial roles in cell functions and diseases, but understanding their dynamics can be challenging.
  • Optogenetics provides a way to precisely control the condensation of proteins, allowing researchers to manipulate when and how these condensates form and dissolve.
  • The review covers the current methods of optogenetically controlling condensation, examines the proteins involved, and highlights both current applications and future possibilities in this field.

Article Abstract

Biomolecular condensates appear throughout cell physiology and pathology, but the specific role of condensation or its dynamics is often difficult to determine. Optogenetics offers an expanding toolset to address these challenges, providing tools to directly control condensation of arbitrary proteins with precision over their formation, dissolution, and patterning in space and time. In this review, we describe the current state of the field for optogenetic control of condensation. We survey the proteins and their derivatives that form the foundation of this toolset, and we discuss the factors that distinguish them to enable appropriate selection for a given application. We also describe recent examples of the ways in which optogenetic condensation has been used in both basic and applied studies. Finally, we discuss important design considerations when engineering new proteins for optogenetic condensation, and we preview future innovations that will further empower this toolset in the coming years.

The precise spatial and temporal regulation of cell-cell adhesions is crucial for understanding the underlying biological processes and for assembling multicellular structures in tissue engineering. Traditional approaches have relied on chemical membrane functionalization and regulated gene expression of native cell adhesion molecules (CAMs), but these methods lack the necessary control and can be detrimental to cells. In contrast, engineered photoswitchable cell-cell adhesions offer a reversible and dynamic regulation at a single-cell resolution.

Membraneless organelles (MLOs) formed via protein phase separation have garnered significant attention recently due to their relevance to cellular physiology and pathology. However, there is a lack of tools available to study their behavior and control their bioactivity in complex biological systems. This chapter describes a new optogenetic tool based on water-soluble chlorophyll protein (WSCP), a red light-induced singlet oxygen-generating protein, to control synthetic MLOs.

Organelles play essential roles in cellular homeostasis and various cellular functions in eukaryotic cells. The current experimental strategy to modulate organelle functions is limited due to the dynamic nature and subcellular distribution of organelles in live cells. Optogenetics utilizes photoactivatable proteins to enable dynamic control of molecular activities through visible light.
