enzymatic reaction

Notch extracellular truncation (NEXT) is the physiologic substrate of gamma-secretase. NEXT cleavage occurs between gly1743 & val1744 of parent Notch-1 (S3). Cleavage serves to release the NOTCH1 intracellular domain (NICD) from the membrane. NICD then translocates to the nucleus, where it functions as a transcriptional activator in concert with CSL family members.
