      DescriptionAnti-Notch 1 Antibody, extracellular
      Alternate Names
      • Notch homolog 1, translocation-associated (Drosophila)
      • Notch (Drosophila) homolog 1 (translocation-associated)
      • Translocation-associated notch protein TAN-1
      • neurogenic locus notch homolog protein 1
      Background InformationThe notch gene belongs to a family of epidermal growth factor (EGF) like homeotic genes, which encode transmembrane proteins with a variable number of cysteine-rich EGF-like repeats in the extracellular region. Four notch genes have been described in mammals, which include notch-1. notch-2, notch-3, and notch-4(Int-3), which have been implicated in the differentiation of the nervous system and other structures. The EGF-like proteins Delta and Serrate have been identified as ligands of notch-1. Mature notch proteins are heterodimeric receptors derived from the cleavage of notch pre-proteins into an extracellular subunit (NEC) containing multiple EGF-like repeats and a transmembrane subunit including intracellular region (Ntm).

      UniProt Number
      UniProt SummaryFUNCTION: 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 RBP-J kappa and activates genes of the enhancer of split locus. Affects the implementation of differentiation, proliferation and apoptotic programs. 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 (By similarity). Acts instructively to control the cell fate determination of CNS multipotent progenitor cells, resulting in astroglial induction and neuron/oligodendrocyte suppression.

      SUBUNIT STRUCTURE: Heterodimer of a C-terminal fragment N(TM) and an N-terminal fragment N(EC) which are probably linked by disulfide bonds. Interacts with DNER, DTX1, DTX2 and RBPSUH. Also interacts with MAML1, MAML2 and MAML3 which act as transcriptional coactivators for NOTCH1 (By similarity).

      SUBCELLULAR LOCATION: Cell membrane; Single-pass type I membrane protein (By similarity).

      Notch 1 intracellular domain: Nucleus (By similarity). Note: Following proteolytical processing NICD is translocated to the nucleus (By similarity).

      TISSUE SPECIFICITY: Expressed in the brain, kidney and spleen. Expressed in postnatal central nervous system (CNS) germinal zones and, in early postnatal life, within numerous cells throughout the CNS. Found in both subventricular and ventricular germinal zones.

      DEVELOPMENTAL STAGE: In the embryo, highest levels occur between days 12 and 14 and decrease rapidly to much lower levels in the adult.

      PTM: 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 (By similarity).

      Phosphorylated (By similarity).

      O-glycosylated on the EGF-like domains. Contains both O-linked fucose and O-linked glucose (By similarity).

      SEQUENCE SIMILARITIES: Belongs to the NOTCH family.

      Contains 5 ANK repeats.

      Contains 36 EGF-like domains.

      Contains 3 LNR (Lin/Notch) repeats.
      Molecular Weight~260 kDa observed. Notch 1, extracellular is calculated at ~183 kDa.
