Background Information

NOTCH3 belongs to the NOTCH family. It 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. NOTCH3 affects the implementation of differentiation, proliferation and apoptotic programs. Defects in NOTCH3 are the cause of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). The antibody is specific to NOTCH3. Notch3 is a single-pass type I membrane protein exposed at the cell surface as a heterodimer of 2321 amino acids. It is synthesized as a precursor with a molecular weight of ~280 kDa (Notch3 full-length), which is cleaved (S1 cleavage) into a 210 kDa extracellular fragment and a 97 kDa intracellular fragment (PMID: 21702048).
