Notch/LIN-12 signaling: transduction by regulated protein slicing

Trends Biochem Sci. 1998 Sep;23(9):353-7. doi: 10.1016/s0968-0004(98)01263-8.

Abstract

Intercellular signaling through the Notch/LIN-12 transmembrane receptors regulates growth and differentiation during animal development. Moreover, defects in the conserved Notch/LIN-12 pathway are linked to human diseases. Here, we review models for two key steps in Notch/LIN-12 signaling: ligand-mediated activation of the receptor and receptor-mediated activation of transcription. Ligand binding appears to permit proteolysis of the receptor; as a result, the receptor's intracellular domain can enter the nucleus and function as a transcriptional co-activator.
