Background: Notch is a family of single-pass transmembrane receptor proteins that are synthesized in the endoplasmic reticulum as an inactive form and are proteolytically cleaved on an extracellular site by a furin-like convertase (S1 cleavage) in the trans-golgi network after the recognition of the RQRR sequence before it reaches the plasma membrane as heterodimers to yield an active, ligand-accessible form. The Notch family is comprised of 4 members (1-4) whose ligands include the Delta and Jagged family of ligands. These ligands cause proteolysis of Notch to liberate the intracellular domain. Cleavage results in a C-terminal fragment N(TN) and a N-terminal fragment N(EC). Following ligand binding, it is cleaved (S2 cleavage) by TNF-alpha converting enzyme (TACE) to yield a membrane-associated intermediate fragment called Notch extracellular truncation (NEXT). This fragment is then cleaved by presenilin-dependent gamma-secretase between gly1743 and val1744 (S3 cleavage) to release the intracellular domain (NICD) from the membrane. That domain translocates to the nucleus and initiates transcription events by binding the DNA binding protein CSL. The notch family members are involved cell differentiation and development.
