Functional conservation of Notch1 and Notch2 intracellular domains.

Abstract excerpt

The Notch receptor is a key component of a highly conserved signaling pathway that regulates cell fate determination during development. In Drosophila, where Notch signaling was first identified and studied, there is only one Notch receptor. In contrast, mammals have four Notch receptor genes, Notch1-4. Notch1 and Notch2 are both required for embryo viability, are widely expressed in mammals, and are structurally...
