Part:BBa_K2549019

LaG16-2-mN1c-tTAA

This part is the second version of our SynNotch receptors, as original published^[1]. LaG16-2 (Part:BBa_K2446058) 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 transactivator^[2], which is cleaved after SynNotch activation and drives the expression of the amplifier.

SynNotch receptors function well in Morsut L et al 2016

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

Morsut L 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).

Please refer to the original article for more details.
