Preparation and Storage

Background: Notch-4

Notch-4 is a 250 kDa member of the NOTCH family of proteins. It is primarily expressed on endothelium. Human Notch-4 is a 1980 amino acid (aa) type I transmembrane (TM) glycoprotein that contains a 1424 aa extracellular domain (ECD) and a 535 aa cytoplasmic region. Notch-4 undergoes proteolytic processing at multiple sites. There is probable cleavage of the ECD by furin in the Golgi between aa 1310‑1410. This creates a mature, potentially disulfide-linked heterodimer at the cell surface. Upon ligand binding, two sequential cleavages occur, one in the ECD after Ala1431, and a second in the TM domain after Lys1466. This creates a soluble cytoplasmic fragment that interacts with RBP-J kappa and activates genes associated with HES-1. Over cytoplasmic aa 1778‑2003, human Notch‑4 is 78% aa identical to mouse Notch-4.
