Structure of LNR-HD (Negative Regulatory Region) from human Notch 2
Overview
Notch receptors transmit signals between adjacent cells. Signaling is, initiated when ligand binding induces metalloprotease cleavage of Notch, within an extracellular negative regulatory region (NRR). We present here, the X-ray structure of the human NOTCH2 NRR, which adopts an autoinhibited, conformation. Extensive interdomain interactions within the NRR bury the, metalloprotease site, showing that a substantial conformational movement, is necessary to expose this site during activation by ligand., Leukemia-associated mutations in NOTCH1 probably release autoinhibition by, destabilizing the conserved hydrophobic core of the NRR.
