Definition
Notch and Jagged proteins define an evolutionarily conserved signal transduction pathway that is critically important for cell fate decisions in metazoan development. Notch and Jagged are single pass membrane-spanning proteins that share a receptor/ligand relationship, respectively. Jagged is the mammalian orthologue of the Drosophila Serrate gene. Collectively, the Notch ligands are referred to as the DSL proteins (Delta/Serrate/Lag). Constitutive activation of the Notch signaling pathway by chromosomal translocation, point mutation, or gene amplification plays a role in tumor initiation and/or progression. Aberrant expression of the intracellular portion of Notch proteins (NotchIC) is associated with the oncogenic transformation of cells. Notch was linked to cancer through its frequent mutation in T-cell acute lymphoblastic leukemia (T-ALL).
Characteristics
DSL proteins are encoded by the Serrate and Delta genes. Drosophila melanogaster possess only a single Serrate, Delta...
