Target

  • 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. May be important for normal lymphocyte function. In altered form, may contribute to transformation or progression in some T-cell neoplasms. Involved in the maturation of both CD4+ and CD8+ cells in the thymus. May be important for follicular differentiation and possibly cell fate selection within the follicle. During cerebellar development, may function as a receptor for neuronal DNER and may be involved in the differentiation of Bergmann glia.
  • Tissue specificity
    In fetal tissues most abundant in spleen, brain stem and lung. Also present in most adult tissues where it is found mainly in lymphoid tissues.
  • Involvement in disease
    Defects in NOTCH1 are a cause of bicuspid aortic valve (BAV) [MIM:109730]. A common defect in the aortic valve in which two rather than three leaflets are present. It is often associated with aortic valve calcification and insufficiency. In extreme cases, the blood flow may be so restricted that the left ventricle fails to grow, resulting in hypoplastic left heart syndrome.
  • Sequence similarities
    Belongs to the NOTCH family.
    Contains 5 ANK repeats.
    Contains 36 EGF-like domains.
    Contains 3 LNR (Lin/Notch) repeats.
  • Post-translational
    modifications
    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.
    Phosphorylated.
    O-glycosylated on the EGF-like domains. Contains both O-linked fucose and O-linked glucose.
    Ubiquitinated; undergoes 'Lys-29'-linked polyubiquitination catalyzed by ITCH.
  • Cellular localization
    Cell membrane and Nucleus. Following proteolytical processing NICD is translocated to the nucleus.

Customer reviews and Q&As

Answer

Thank you again for your email and patience while I have been trying to obtain additional information regarding this antibody. Unfortunately, there is no additional information regarding the testing of antibody, including a Western blot image. A colleague and I compared the human and mouse Notch1 intra sequences (amino acids 2488-2502) and there is 93% homology between the two sequences. Also, the epitope recognized by this antibody may be exposed in the cleaved form, but not in the full length form, even though the sequence is found in both. What dilution of ab8387 are you using? What is your secondary antibody and what dilution are you using? Have you done a secondary-only control to ensure that the secondary is not binding non-specifically? Also, what is your order number? Please rest assured that we guarantee our antibodies to work as stated on the online datasheets. I will do my best to troubleshoot this problem, and can offer you ca refund or replacement. Thanks you again, and I look forward to hearing from you.
