Summary
fluorescein-conjugated extracellular matrix (ECM)-binding peptides can be used to regulate SynNotch activity depending on the folding state of collagen-based ECM networks
Usefulness & Problems
Why this is useful
These fluorescein-conjugated ECM-binding peptides regulate SynNotch activity in a way that depends on the folding state of collagen-based ECM networks. They connect extracellular matrix state to receptor signaling.; regulating SynNotch activity from matrix-based cues; coupling collagen network state to gene expression control

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.
