Murine ADAM10 cleaves Notch at the S2 site producing transmembrane spanning NEXT and ligand-bound NECD
Cleavage of mouse Notch1 at the S2 site precedes the gamma-secretase-mediated cleavage at the S3 site. It was initially shown that a membrane bound mouse Notch1 fragment exogenously expressed in HEK 293 cells is cleaved at S2 by human ADAM17 isolated from HeLa cells (Brou et al. 2000). However, experiments in which Notch1 cleavage at S2 was examined in mouse fibroblasts deficient for one of the Adam enzymes (Adam9, Adam10, Adam12, Adam15 or Adam17), stimulated by co-culture with cells expressing mouse Jag1, showed that Adam10, a homologue of Drosophila Kuzbanian, was required for the S2 cleavage (van Tetering et al. 2009). Adam10 knockout mice die at embryonal day 9.5 with multiple defects in the developing central nervous system, somites and cardiovascular system. The neural tube of Adam10 deficient embryos exhibits decreased expression of the Notch gene target Hes5 (Hartmann et al. 2002).
