Selective Use of ADAM10 and ADAM17 in Activation of Notch1 Signaling

Open access

Abstract

Notch signaling requires a series of proteolytic cleavage events to release the Notch intracellular domain (NICD) that functions directly in signal transduction. The Notch receptor is locked down in a protease-resistant state by a negative regulatory region (NRR) that protects an ADAM (a disintegrin and metalloprotease) cleavage site. Engagement with ligand-bearing cells induces global conformational movements in Notch that unfold the NRR structure to expose the ADAM cleavage site and initiate proteolytic activation. Although both ADAM10 and ADAM17 have been reported to cleave Notch to facilitate NICD release by gamma-secretase, the relevant ADAM has remained controversial. Our study provides new insight into this conflict, as we find that although Notch1 (N1) is a substrate for both ADAM10 and ADAM17, the particular ADAM required for receptor activation is context dependent. Specifically, ADAM10 was absolutely required for N1 signaling induced by ligands, while signaling independent of ligands required ADAM17. In contrast to the strict and differential use of ADAM10 and ADAM17 in normal and dysregulated signaling, respectively, both proteases participated in signaling intrinsic to N1 mutations associated with leukemia. We propose that in addition to exposing the ADAM cleavage site, activating N1 conformational changes facilitate selective cleavage by specific proteases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
