Anti-Notch 1, extracellular, clone 8G10

P46531

FUNCTION: SwissProt: P46531 # 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 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 (By similarity).
SIZE: 2556 amino acids; 272500 Da
SUBUNIT: 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.
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: 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.
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).
DISEASE: SwissProt: P46531 # NOTCH1 truncation is associated with T-cell acute lymphoblastic leukemia. & Defects in NOTCH1 are a cause of aortic valve disease [MIM:109730]. The disorder consists of an early developmental defect in the aortic valve and a later de-repression of calcium deposition that causes progressive aortic valve disease. Calcification of the aortic valve is the third leading cause of heart disease in adults. The incidence increases with age, and it is often associated with a bicuspid aortic valve present in 1-2% of the population.
SIMILARITY: SwissProt: P46531 ## Belongs to the NOTCH family. & Contains 5 ANK repeats. & Contains 36 EGF-like domains. & Contains 3 LNR (Lin/Notch) repeats. ... ausblenden » weitere anzeigen »

NM_017617.3

This gene encodes a member of the Notch family. Members of this Type 1 transmembrane protein family share structural characteristics including an extracellular domain consisting of multiple epidermal growth factor-like (EGF) repeats, and an intracellular domain consisting of multiple, different domain types. Notch family members play a role in a variety of developmental processes by controlling cell fate decisions. The Notch signaling network is an evolutionarily conserved intercellular signaling pathway which regulates interactions between physically adjacent cells. In Drosophilia, notch interaction with its cell-bound ligands (delta, serrate) establishes an intercellular signaling pathway that plays a key role in development. Homologues of the notch-ligands have also been identified in human, but precise interactions between these ligands and the human notch homologues remain to be determined. This protein is cleaved in the trans-Golgi network, and presented on the cell surface as a heterodimer. This protein functions as a receptor for membrane bound ligands, and may play multiple roles during development. ... ausblenden » weitere anzeigen »

Anti-Notch 1, extracellular, clone 8G10

Notch 1 is a type 1 membrane protein that serves as a receptor for the membrane bound ligands jagged-1 and -2 and delta-1 to regulate cell fate determination through the implementation of differentiation, proliferation and apoptotic programs. Upon ligand binding, the Notch intracellular domain (NICD) is released by proteolytic processing and subsequently translocates to the nucleus where it forms a transcriptionally active complex with RBP-J kappa to activate genes of the enhancer of split locus. Notch-1 may also be involved in cell specification and/or differentiation and body segment determination in the postimplantation embryo. In the adult animal, Notch-1 is highly expressed in the brain, lung, and thymus with lower expression levels in the spleen, bone-marrow, spinal cord, eyes, mammary gland, liver, intestine, skeletal muscle, kidney and heart.

8G10

Reacts with natural and recombinant Notch1. Recognizes a band migrating at approximately 300 kDa on Western blots of rat and mouse protein extracts. A cross reactive band migrating at approximately 230 kDa is observed in some samples and is believed to correspond to the processed extracellular fragment of Notch 1.
