Part:BBa_K2549016

LaG17-mN1c-tTAA

This part is one of our SynNotch receptors. LaG17 (Part:BBa_K2549004) is used as the extracellular sensor module to receive the signal input from GFP. mN1c (Part:BBa_K2549006) is served as the transmembrane core domain of SynNotch, which is evident to have a low basal expression and a high activation efficiency. tTAA (Part:BBa_K2446057) is an improved tetracycline-controlled transcription activator, which is cleaved after SynNotch activation and drives the expression of the amplifier. Besides, a CD8α signal peptide (Part:BBa_K2549044) and a Myc-tag (Part:BBa_K823036) are added to the N terminal of LaG17(Part:BBa_K2549004) for membrane targeting and easy determination of surface expression.

Biology

SynNotch receptors function well in Lim WA et al in 2016

Lim WA et al stated:SynNotch receptors provide extraordinary flexibility in engineering cells with customized sensing/response behaviors to user-specified extracellular cues.

Lim WA et al have shown that modularity of the synNotch platform. They stated : "the input and output domains from Notch can be swapped with diverse domains. On the extracellular side, diverse recognition domains can be used (antibody based, or peptide tags are shown) and on the intracellular side, diverse effector can be used (transcriptional activators with different DNA-binding domains are shown, as well as a transcriptional repressor)."

LaG17-mN1c-tTAA works as expected
