TRKC Effector Reporter Cell
CBP74500
| I. Background | |
| TrkC(原肌球蛋白受體激酶 C)是神經(jīng)營(yíng)養因子受體 Trk 家族的重要成員,由 NTRK3 基因編碼,作為一種受體酪氨酸激酶,它主要與其特異性配體神經(jīng)營(yíng)養因子-3(NT-3)結 合,并在中樞和外周神經(jīng)系統的特定區域高表達,尤其在與運動(dòng)協(xié)調和平衡相關(guān)的本體感 覺(jué)神經(jīng)元以及小腦中發(fā)揮關(guān)鍵作用,主導神經(jīng)元的存活、分化與突觸可塑性。 NT-3/TRKC 信號通路是調控神經(jīng)系統發(fā)育與功能的核心通路,其中 NT-3 作為特異性 配體,與受體酪氨酸激酶 TRKC 結合后,誘導其發(fā)生二聚化及自磷酸化,從而激活下游 R AS/MAPK(增殖/分化)、PI3K/AKT(存活)和 PLC-γ(可塑性)三條關(guān)鍵信號級聯(lián),共 同介導神經(jīng)元的存活、分化、軸突生長(cháng)及突觸可塑性,尤其對本體感覺(jué)等功能至關(guān)重要; 而該通路的病理激活源于 NTRK3 基因融合,導致 TRKC 激酶域發(fā)生配體非依賴(lài)性的持續 激活,進(jìn)而將這一維持神經(jīng)生存的生理通路轉化為驅動(dòng)多種癌癥的致癌引擎,成為廣譜靶 向藥物的作用基礎。 |
