The neurogenic locus notch homolog protein 3 is a protein encoded by the NOTCH3 gene. There are 4 notch receptors in mammals, all of which are transmembrane proteins and notch signalling regulates a very diverse set of biological functions; The most commun is the cell lineage determination. Therefore, changes in the activity of these receptors is associated with various benign and malignant diseases as T-ALL (T-lineage acute lymphoblastic leukemia). T-ALL is characterized by the uncontrolled proliferation of T-cell lymphoblasts in the blood, the brown marrow and the tissues. | The neurogenic locus notch homolog protein 3 is a protein encoded by the NOTCH3 gene.

cells produce two types of daughter cells, the nutrient-absorbing enterocytes (ECs) and secretory enteroendocrine (ee) cells. Notch signalling between intestinal stem cells and their daughter cells guides cell specification. ISCs with elevated levels of the Notch Delta ligand more primarily activate the Notch signalling pathway in daughter cells and cause them to become ECs. However, ISCs having low levels of Notch Delta ligand direct daughter cells to become ee cells. | cells produce two types of daughter cells, the nutrient-absorbing enterocytes (ECs) and secretory enteroendocrine (ee) cells.
