Neurofibromin (NF1) mutations cause neurofibromatosis type 1 and drive numerous cancers, including breast and brain tumors. NF1 inhibits cellular proliferation through its guanosine triphosphatase-activating protein (GAP) activity against rat sarcoma (RAS). In the present study, cryo-electron microscope studies reveal that the human ~640-kDa NF1 homodimer features a gigantic 30 × 10 nm array of α-helices that form a core lemniscate-shaped scaffold. Three-dimensional variability analysis captured the catalytic GAP-related domain and lipid-binding SEC-PH domains positioned against the core scaffold in a closed, autoinhibited conformation. We postulate that interaction with the plasma membrane may release the closed conformation to promote RAS inactivation. Our structural data further allow us to map the location of disease-associated NF1 variants and provide a long-sought-after structural explanation for the extreme susceptibility of the molecule to loss-of-function mutations. Collectively these findings present potential new routes for therapeutic modulation of the RAS pathway. 履歴 登録 2021年5月4日 - ヘッダ(付随情報) 公開 2021年12月15日 - マップ公開 2021年12月15日 - 更新 2024年5月29日 - 現状 2024年5月29日 処理サイト : RCSB / 状態 : 公開
