Taxonomy: Mechanism Branch / Component. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Additional high-signal enrichment leads cluster into four useful categories: foundational CALI methodology, mechanistic papers explaining ROS-mediated inactivation, genetically encoded photosensitizer/tool-development papers (notably KillerRed, miniSOG, SuperNova), and representative application papers in neurons, mitochondria, nuclei, and whole-animal cell ablation.

miniSOG is associated with correlative light and electron microscopy applications in the supplied source scaffold.
SuperNova and miniSOG are associated with chromophore-assisted light inactivation workflows in the supplied source scaffold.
At the organelle level, including mitochondria, plasma membrane, or lysosomes, CALI can trigger cell death.
CALI can provide information about individual events involved in target protein function and highlight them within multifactorial events.
CALI has emerged as an optogenetic tool to switch off signaling pathways, including optical depletion of individual neurons.
CALI of nuclear proteins can induce cell cycle arrest and chromatin- or locus-specific DNA damage.
Rescue experiments can clarify phenotypic capabilities after CALI depletion of endogenous targets.
Using spatially restricted microscopy illumination, CALI can address protein isoform, subcellular localization, and phase-specific questions that RNA interference or chemical treatment cannot.
CALI is performed using photosensitizers that generate reactive oxygen species.
CALI enables spatiotemporal knockdown or loss-of-function of target molecules in situ.
The review describes two CALI approaches: transgenic tags with chemical photosensitizers and genetically encoded fluorescent protein fusions.
This review centers on genetically encoded ROS-generating proteins for optogenetic control of reactive oxygen species, with KillerRed, miniSOG, and SuperNova highlighted as core examples.
