Fig. 1

The ligand-binding N-terminal extracellular domain includes the repeat EGF domain followed by three Lin-12/Notch repeats (LNR) and the heterodimerization domain (HD). The LNR segments and the HD comprise the NRR. The transmembrane segment follows. The cytosolic domain contains the RAM domain, followed by ankyrin (ANK) repeats, the transcriptional activation domain (TAD), and the C-terminal terminal proline-, glutamic acid–, serine-, and threonine-rich (PEST) domain. The construct used in this study (the Notch-TMD) is the transmembrane segment plus the immediate juxtamembrane regions, highlighted on the right. Major γ-secretase cut sites are labeled red. The S2 metalloprotease cut site precedes Val1721.
