Neurogenic Locus Notch Homolog Protein 1 Cleaved-Val1754 (NOTCH1 Cleaved-V1754) Antibody

Background

NOTCH1 is a transmembrane receptor of the Notch signaling pathway, which regulates critical processes such as cell fate determination, proliferation, differentiation, and apoptosis during development and tissue homeostasis. Upon ligand binding (e.g., Jagged or Delta-like ligands), the NOTCH1 receptor undergoes proteolytic cleavage, releasing its intracellular domain (NICD). NICD translocates to the nucleus, activating transcription of target genes, including HES and HEY family members, to modulate cell behavior. Dysregulation of NOTCH1 contributes to various diseases, including cancers such as T-cell acute lymphoblastic leukemia (T-ALL), where activating mutations drive aberrant proliferation. In addition, NOTCH1 plays a role in cardiovascular development, neural differentiation, and immune system regulation. Knockout studies reveal embryonic lethality due to disrupted vascular development and neurogenesis, demonstrating its essential role in embryonic and adult tissue homeostasis, cellular differentiation, and oncogenesis.
