Background: Notch-1

Notch-1 (so named for "notches" in fly wings; also TAN-1) is a 300 kDa member of the Notch family of glycoproteins. It is associated with gene activation in both embryo and adult. Human Notch-1 is a 2538 amino acid (aa) type I transmembrane glycoprotein. It undergoes Golgi processing to generate a heterodimer composed of a 180‑200 kDa disulfide-linked extracellular domain (aa 18‑1664) and a 120 kDa membrane-bound segment (aa 1665‑2556). Upon ligand binding, the 110 kDa segment undergoes two cleavages which generate an NICD (notch intracellular domain) (aa 1754‑2556), a nuclear transcription factor. One isoform shows a deletion of aa 248‑288. Over aa 2428‑2556, human Notch 1 is 83% and 89% aa identical to canine and mouse Notch-1, respectively.
