  • General notes

    Notch 1 (encoded by the Notch 1 gene) is a member of the Notch family of receptors. When bound to a ligand, the Notch1 receptor sends signals critical for normal development of many tissues throughout the body. Notch1 signalling supports the determination and specialization of cells as well as playing a role in cell proliferation, differentiation, and apoptosis.

    This product is a recombinant monoclonal antibody, which offers several advantages including:

    • - High batch-to-batch consistency and reproducibility
    • - Improved sensitivity and specificity
    • - Long-term security of supply
    • - Animal-free production

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.

    Answer

    Thank you for contacting us. The database entry for the human NOtch1 protein is as follows: http://www.uniprot.org/uniprot/P46531 There you will find more information about the protein structure, sequences and additional references. In regards as to why you see band at 110-120 kDa: The predicted MW is 270 kDa for the full length unprocessed precursor. If the protein has splice variants or can be cleaved, than shorter versions of the protein can be detected - if they contain the immunogen sequence (cytoplasmic portion). According to the database entry, the protein can get cleaved into Notch 1 extracellular truncation and Notch 1 intracellular domain. The antibody would be able to recognize then the intracellular domain. However, under which condition the cleavage happens, I am not certain. I would suggest to consult the literature for this detailed information.   I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
