title: The ADAM family: Insights into Notch proteolysis.
abstract: Notch signaling is integral to a large number of developmental and homeostasis events, and either gain or loss of Notch signaling results in a wide range of defects. Notch must be processed by several proteases, including a member of the ADAM (a disintegrin and metalloprotease) family to mediate downstream signaling. Until recently, interactions of Notch with specific ADAMs in different contexts were unclear. ADAM10 is now known to be specifically essential for development and homeostasis of mouse epidermis and cardiovascular structures, and ADAM17 may not be able to fully replace ADAM10 in these contexts. However, Notch from T-cell acute lymphoblastic leukemia (T-ALL) patients can be cleaved by both ADAMs 10 and 17. Studies have revealed that ADAM10 is necessary for Notch processing when Notch is activated by a ligand, while ADAM17 is the major protease for processing Notch that is activated independently of ligand in both flies and mammals.
