Abstract
The Notch receptors have attracted considerable attention for their ability to control cellular functions that regulate embryo development and tissue homeostasis. Notch receptors act by controlling the expression of a specific set of target genes. If Notch signaling system can be so simple, and yet so complex in its pleiotropic effects, then a sophisticated network of regulatory mechanisms is required to maintain the control over the initiation, activity and termination of this signaling pathway. A multitude of regulatory mechanisms has been discovered that controls the interaction of Notch receptors with their ligands, the assembling of a Notch transcriptional activation complex and the termination of Notch signals. The intracellular and extracellular domains of the Notch receptors are synthesized as single proteins, pairing with each other during their trafficking through the exocytotic route. The mechanisms operating in the phase preceding the generation of the heterodimeric signal-I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
