    text
  • type II membrane protein
  • a soluble form may be derived from the membrane form by proteolytic processing
  • basic FUNCTION
  • essential mediator of somite segmentation and patterning
  • putative regulator of developmental processes through alternative regulation of the sensitivity of NOTCH receptor genes for their specific ligands (delta, Jagged 2)
  • glycosyl transferase with N-acetylglucosaminyltransferase activity with elongation of 0-linked fucose residues, on side chains located at some of the EGF-repeats of NOTCH
  • decreasing the binding of jagged 1 to Notch2 but not that of DELTA1
  • inhibiting Notch1 signaling in the presomitic mesoderm (Dunwoodie 2009)
  • involved in the regulation of T lymphopoiesis (Visan 2006)
