Summary
This tool is an RNA aptamer-based component for light-controlled, reversible gene transactivation in a CRISPR/dCas9-based system. It is built on the interaction between the photoreceptor PAL and an RNA aptamer to regulate gene expression with light.

The construct is based on coupling the photoreceptor PAL to an RNA aptamer within a CRISPR/dCas9 gene activation framework. The available evidence supports light-controlled operation and modular design, but does not specify wavelengths, expression systems, delivery methods, or exact construct architecture.
The supplied evidence does not provide quantitative performance metrics, illumination parameters, target genes, or organism-specific validation details. Independent replication beyond the cited study is not provided in the evidence.
