NOTCH1

NOTCH1 encodes a protein known as Notch homolog 1, a single-pass transmembrane receptor with common aliases like TAN1. This protein plays a crucial role in cell fate determination, proliferation, and apoptosis. It functions through a proteolytic cleavage mechanism, releasing the Notch intracellular domain that translocates to the nucleus and activates target genes. The Notch signaling pathway is highly conserved and is involved in multiple cellular processes.
Dysregulation of NOTCH1 is associated with various diseases, such as T - cell acute lymphoblastic leukemia (T - ALL) and some solid tumors. In drug development, targeting the Notch pathway has become an area of active research. Several small - molecule inhibitors and monoclonal antibodies are in pre - clinical and clinical trials to potentially offer new treatment options for related diseases.
