Notch-2 (also Motch-2) is a 280-300 kDa member of the notch family of transmembrane (TM) proteins. It is found on multiple cell types and exhibits multiple functions. On CD8+ T cells, it augments cytotoxic activity; on pre-B cells, it drives B1 B cell development; on endothelial cells, it induces apoptosis; and on proerythroblasts, it promotes proliferation. Mature mouse Notch-2 is a 2445 amino acid (aa) type I TM glycoprotein. It undergoes Golgi processing to generate a 180-200 kDa extracellular domain (ECD) (aa 26-1606) possibly covalently-linked to a 100-110 kDa membrane bound C-terminal segment (aa 1607-2470). Upon binding to Delta1, Jagged1, or Jagged2, the 110 kDa segment undergoes two cleavages, the second of which generates an NICD (notch intracellular domain) that serves as a potential nuclear transcription factor. There are three potential splice variants. One shows a 32 aa substitution for aa 293-2470, a second contains a 13 aa substitution for aa 1-1954, and a third possesses a five aa substitution for aa 224-227 coupled to an 11 aa substitution for aa 1704-1713. Over aa 26-528, mouse Notch-2 shares 96% and 94% aa sequence identity with rat and human Notch-2, respectively.
