  • Function
    Functions as a receptor for membrane-bound ligands Jagged1, Jagged2 and Delta1 to regulate cell-fate determination. Upon ligand activation through the released notch intracellular domain (NICD) it forms a transcriptional activator complex with RBPJ/RBPSUH and activates genes of the enhancer of split locus. Affects the implementation of differentiation, proliferation and apoptotic programs.
  • Tissue specificity
    Ubiquitously expressed in fetal and adult tissues.
  • Involvement in disease
    Defects in NOTCH3 are the cause of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) [MIM:125310]. CADASIL causes a type of stroke and dementia of which key features include recurrent subcortical ischemic events and vascular dementia. The disorder affects relatively young adults of both sexes. Mutations affect highly conserved cysteine residues within epidermal growth factor (EGF)-like repeat domains in the extracellular part of the receptor.
  • Sequence similarities
    Belongs to the NOTCH family.
    Contains 5 ANK repeats.
    Contains 34 EGF-like domains.
    Contains 3 LNR (Lin/Notch) repeats.
  • Post-translational
    Synthesized in the endoplasmic reticulum as an inactive form which is proteolytically cleaved by a furin-like convertase in the trans-Golgi network before it reaches the plasma membrane to yield an active, ligand-accessible form. Cleavage results in a C-terminal fragment N(TM) and a N-terminal fragment N(EC). Following ligand binding, it is cleaved 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 to release a notch-derived peptide containing the intracellular domain (NICD) from the membrane.
  • Cellular localization
    Cell membrane and Nucleus. Following proteolytical processing NICD is translocated to the nucleus.

  • Staining of CD4+CD8+ (blue histogram) and CD4-CD8-CD25+CD44- (purple histogram) C57BL/6 thymocytes with 0.5 µg of Armenian Hamster IgG Isotype Control PE (left) or 0.25 µg of ab95775 (right). Total viable cells were used for analysis.
  • ICC/IF image of ab95775 stained mouse epiblast stem cells (EpiSCs). The cells were paraformaldehyde fixed and then permeabilized in 0.1% triton, before blocking in 10% Serum, for 1 hour at +4ºC. Cells were then incubated with this antibody (ab95775, 1/200) for 12 hours at +4ºC. DAPI was used to stain the nuclei (blue).
