This GFP reporter plasmid expresses Notch1CR2, a noncoding sequence upstream of the Notch1 locus.
The LIN-12/Notch family of transmembrane receptors plays a central role in development by regulating cell fate decisions. The Notch proteins have been found to be overexpressed or rearranged in human tumors. Ligands for Notch include Jagged, Jagged2 and Delta. Jagged can activate Notch and prevent myoblast differentiation by inhibiting the expression of muscle regulatory and structural genes. Jagged2 is thought to be involved in the development of various tissues whose development is dependent upon epithelial-mesenchymal interactions. Normal Delta expression is restricted to the adrenal gland and placenta. Delta expression has also been found in neuroendocrine tumors such as neuroblastomas and pheochromocytomas.

CR2 directs reporter GFP expression in embryonic chick CNS.
(A-B) whole mount images of transfee ted chick embryos at E4 two days after electroporation at E2 (HH12). CR2-GFP expression was observed only in the CNS. CAG-GFP expression (the transfection controls) was obs erved in both the CNS and non-CNS tissues. e.g.. the visceral arch (arrowhead).
