Notch 1 is a transmembrane protein functioning in the development and determination of cell-fate (1). During maturation, the Notch molecule is cleaved by furin-like convertase at the extracellular domain (2). Upon binding to a ligand such as Delta1, or upon extracellular calcium depletion, the C-terminal Notch 1 fragment dissociates from its N-terminal counterpart and is further cleaved between Gly1743 and Val1744 (3,4). The resulting activated cytosolic fragment translocates to the nucleus and activates Notch-related transcription. Applications: Suitable for use in Western Blot, Immunoprecipitation, and ELISA.
