Notch-Gal4-VP16 Juxtacrine Signaling Receptor MammoBlock

This part encodes a major mammalian cell-signaling protein, the Notch-1 receptor, engineered to replace the original 12xCSL-binding transactvation domain with the Gal4-VP16 transactivator (Gal4-ESN). In the presence of the Delta ligand protein from another cell, this transactivation domain is cleaved and released to the Notch producing cell's nucleus. In contrast, if Delta is present on the Notch producing cell, the Delta protein will cis-inhibit the Notch receptor, desensitizing the receptor to activation from external Delta molecules. This receptor is singularly useful for cell patterning, lineage decision-making, and other forms of signaling-intensive processes.

This version of the Notch signaling protein is expected to induce much stronger levels of activation than those documented in recent work by Sprinzak, et al.
