Inhibition of γ-secretase activity represents a potential therapeutic strategy for Alzheimer's disease (AD). MRK-560 is a selective inhibitor with higher potency for Presenilin 1 (PS1) than for PS2, the two isoforms of the catalytic subunit of γ-secretase, although the underlying mechanism remains elusive. Here we report the cryo-electron microscopy (cryo-EM) structures of PS1 and PS2-containing γ-secretase complexes with and without MRK-560 at overall resolutions of 2.9-3.4 Å. MRK-560 occupies the substrate binding site of PS1, but is invisible in PS2. Structural comparison identifies Thr281 and Leu282 in PS1 to be the determinant for isoform-dependent sensitivity to MRK-560, which is confirmed by swapping experiment between PS1 and PS2. By revealing the mechanism for isoform-selective inhibition of presenilin, our work may facilitate future drug discovery targeting γ-secretase. 履歴 登録 2022年6月18日 - ヘッダ(付随情報) 公開 2022年11月2日 - マップ公開 2022年11月2日 - 更新 2025年7月2日 - 現状 2025年7月2日 処理サイト : PDBj / 状態 : 公開
