The Notch signaling pathway is a highly conserved cell signaling system present in most animals. [1] Mammals possess four different notch receptors , referred to as NOTCH1 , NOTCH2 , NOTCH3 , and NOTCH4 . [ 2 ]
The Notch signaling network is an evolutionarily conserved intercellular signaling pathway that regulates interactions between physically adjacent cells. In Drosophila , notch interaction with its cell-bound ligands (delta, serrate) establishes an intercellular signaling pathway that plays a key role in development.
In Drosophila, notch interaction with its cell-bound ligands (delta, serrate) establishes an intercellular signalling pathway that plays a key role in neural development. Homologues of the notch-ligands have also been identified in human, but precise interactions between these ligands and the human notch homologues remains to be determined.
The signal transduction component labeled as "MAPK" in the pathway was originally called "ERK," so the pathway is called the MAPK/ERK pathway. The MAPK protein is an enzyme, a protein kinase that can attach phosphate to target proteins such as the transcription factor MYC and, thus, alter gene transcription and, ultimately, cell cycle progression.
The Notch signaling pathway is a highly conserved pathway that functions to establish and regulate cell fate decisions in many organ systems. Once the JAG1-NOTCH (receptor-ligand) interactions take place, a cascade of proteolytic cleavages is triggered resulting in activation of the transcription for downstream target genes.

In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells. Akt/PKB signalling pathway; AMPK signalling pathway; cAMP-dependent pathway; Eph/ephrin signalling pathway; Hedgehog signalling pathway; Hippo signalling pathway
The Notch signaling pathway is an evolutionarily conserved intercellular signaling pathway that regulates interactions between physically adjacent cells In Drosophila , notch interacts with its cell-bound ligands (delta and serrate), and establishes an intercellular signaling pathway that then plays a key role in development.
