FunctionFunctions 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 specificityIn 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 diseaseDefects 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 similaritiesBelongs to the NOTCH family.
Contains 5 ANK repeats.
Contains 36 EGF-like domains.
Contains 3 LNR (Lin/Notch) repeats.
modificationsSynthesized 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.
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 localizationCell membrane and Nucleus. Following proteolytical processing NICD is translocated to the nucleus.

ChIP analysis using ab27526 binding Notch1 in mouse pancreatic cancer primary cells. Cells were cross-linked for 12 minutes with 1% formaldehyde. Samples were incubated with the primary antibody at a dilution of 1/50 for 8 hours at 4°C. Protein binding was detected using real-time PCR.
Pol II as was used as a positive control and IgG as background control. GAPDH promoter was used as the non-binding control.

ab27526 staining Notch 1 in Mouse pancreatic cancer primary cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with acetone/methanol (1:1) and blocked with 10% serum for 1 hour at room temperature. Samples were incubated with primary antibody (1/100 in PBS) for 4 hours. An Alexa Fluor®488-conjugated Donkey anti-rabbit IgG polyclonal (ab150073) (1/1000) was used as the secondary antibody. Nuclei were counterstained with DAPI.
