Methods Mol Biol, 26 Dec 2024 DOI: 10.1007/978-1-0716-4047-0 Link to full text
Abstract: This volume explores the latest advancements in the field of optogenetics and how it uses cellular light-sensing components and genetic engineering to control proteins and biological processes. The book chapters are organized into four parts. Part One focuses on intracellular optogenetic components for control of specific cell functions; Part Two looks at externally supplied light regulators that do not require genetic manipulation of target cells; Part Three highlights optogenetic control of organelles, and Part Four introduces technical tools required for light induction in optogenetic experiments, as well as a method for performing and analyzing optogenetic cell-cell adhesion. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and practical, Optogenetics: Methods and Protocols is a valuable resource to help researchers understand and apply the concepts of optogenetics and the underlying bioengineering principles, and establish the required technical light-illumination setups for administering light inputs and analysis of experimental outcomes.

Nat Methods, 30 Jan 2023 DOI: 10.1038/s41592-022-01761-3 Link to full text
Abstract: Lifeact is a popular peptide-based label of actin filaments in live cells. We have designed an improved Lifeact variant, LILAC, that binds to actin in light using the LOV2 protein. Light control allows the user to modulate actin labeling, enabling image analysis that leverages modulation for an enhanced view of F-actin dynamics in cells. Furthermore, the tool reduces actin perturbations and cell sickness caused by Lifeact overexpression.

Investigations of human myosin VI targeting using optogenetically controlled cargo loading.

Proc Natl Acad Sci USA, 13 Feb 2017 DOI: 10.1073/pnas.1614716114 Link to full text
Abstract: Myosins play countless critical roles in the cell, each requiring it to be activated at a specific location and time. To control myosin VI with this specificity, we created an optogenetic tool for activating myosin VI by fusing the light-sensitive Avena sativa phototropin1 LOV2 domain to a peptide from Dab2 (LOVDab), a myosin VI cargo protein. Our approach harnesses the native targeting and activation mechanism of myosin VI, allowing direct inferences on myosin VI function. LOVDab robustly recruits human full-length myosin VI to various organelles in vivo and hinders peroxisome motion in a light-controllable manner. LOVDab also activates myosin VI in an in vitro gliding filament assay. Our data suggest that protein and lipid cargoes cooperate to activate myosin VI, allowing myosin VI to integrate Ca(2+), lipid, and protein cargo signals in the cell to deploy in a site-specific manner.
