Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Here, we introduce an adaptor-based strategy for regulating SynNotch activity via fluorescein isomers and analogs.
Usefulness & Problems
Why this is useful
These adaptors use fluorescein isomers and analogs to regulate SynNotch activity. They are presented as the core strategy enabling chemical, spatial, and matrix-linked control modes.; chemical control of SynNotch activity; linking extracellular and matrix-based cues to gene expression responses

Published Workflows
Objective: Engineer and apply fluorescein-based adaptor strategies to control SynNotch signaling and downstream gene expression in mammalian cells using chemical, spatial, and matrix-based extracellular cues.
Why it works: The workflow uses a fluorescein-binding SynNotch receptor together with different fluorescein-based adaptor formats so that the same receptor platform can be triggered by chemically activated, photo-uncaged, or ECM-associated inputs.
