Notch-mediated juxtacrine signal between adjacent cells Notch signaling steps. 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 receptor is a single-pass transmembrane receptor protein.

Notch proteins are a family of type 1 transmembrane proteins that form a core component of the Notch signaling pathway, which is highly conserved in animals. The Notch extracellular domain mediates interactions with DSL family ligands , allowing it to participate in juxtacrine signaling .
JAG1 was first identified as a ligand that was able to activate notch receptors when the rat gene Jagged encoding a protein homolog was cloned in 1995. [5] [6] The structure of the JAG1 protein includes a small intracellular component, a transmembrane motif, proceeded by an extracellular region containing a cystine-rich region, 16 EGF-like repeats, a DSL domain, and finally a signal peptide ...
Lateral inhibition is described as a part of the Notch signaling pathway, a type of cell–cell interaction. Specifically, during asymmetric cell division one daughter cell adopts a particular fate that causes it to be copy of the original cell and the other daughter cell is inhibited from becoming a copy.
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. Homologues of the notch ...

SOX-9 is a target of the Notch signaling pathway, as well as the Hedgehog pathway, [14] and plays a role in the regulation of neural stem cell fate. In vivo and in vitro studies show that SOX-9 negatively regulates neurogenesis and positively regulates gliogenesis and stem cell survival. [15]
