Enhanced Magnets
Also known as: eMags
Taxonomy: Mechanism Branch / Component. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Enhanced Magnets (eMags) are Vivid-derived light-sensitive protein dimerization domains used in optogenetic split transcription factors and subcellular recruitment systems. In Saccharomyces cerevisiae, optimized eMag-based transcription factor designs improved light-sensitive gene expression, and eMags were also validated for rapid, reversible protein recruitment to subcellular organelles.
Usefulness & Problems
Why this is useful
eMags provide a genetically encoded light-controlled interaction module for regulating transcription and recruiting proteins to defined subcellular locations. The available evidence indicates utility both in yeast optogenetic toolkit development and in subcellular optogenetics requiring rapid and reversible control.

We combine laboratory automation and a modular cloning scheme to enable high-throughput construction and characterization of optogenetic split transcription factors in Saccharomyces cerevisiae .

We validated these “enhanced” Magnets (eMags) by using them to rapidly and reversibly recruit proteins to subcellular organelles, to induce organelle contacts, and to reconstitute OSBP-VAP ER-Golgi tethering implicated in phosphatidylinositol-4-phosphate transport and metabolism.

Magnets are small modules engineered from the Neurospora crassa photoreceptor Vivid by orthogonalizing the homodimerization interface into complementary heterodimers.
Source:
eMags represent a very effective tool to optogenetically manipulate physiological processes over whole cells or in small subcellular volumes.
Problem solved
eMags help solve the problem of controlling protein association with light in a modular format that can be inserted into split transcription factors or recruitment constructs. The cited work specifically addresses improved light-sensitive gene expression in Saccharomyces cerevisiae and reversible organelle-localized protein recruitment.

Implementation Constraints
eMags have been integrated into split transcription factors in Saccharomyces cerevisiae and into constructs for protein recruitment to subcellular organelles. The evidence supports use within modular cloning and high-throughput characterization workflows, but it does not specify cofactors, expression constraints, or detailed construct architecture.
The supplied evidence does not report quantitative performance metrics, illumination wavelengths, dynamic range, kinetics, or comparisons against alternative dimerizers beyond noting improvement after optimization. Validation is described in yeast transcription-factor contexts and subcellular recruitment, so broader organismal and application scope is not established here.
