ATF4
ATF4,即激活轉(zhuǎn)錄因子4,別名CREB-2。ATF4是一種堿性區(qū)域亮氨酸拉鏈轉(zhuǎn)錄因子,屬于bZIP家族成員,由人類基因組中的ATF4基因編碼。它在細(xì)胞對(duì)多種應(yīng)激反應(yīng)的調(diào)控中發(fā)揮關(guān)鍵作用,包括氨基酸缺乏、氧化應(yīng)激和內(nèi)質(zhì)網(wǎng)應(yīng)激等。ATF4的作用機(jī)制主要是通過(guò)結(jié)合到目標(biāo)基因的啟動(dòng)子區(qū)域上的cAMP響應(yīng)元件(CRE)或相關(guān)的DNA序列,調(diào)節(jié)下游基因的轉(zhuǎn)錄。ATF4在生物學(xué)上的意義主要體現(xiàn)在其對(duì)細(xì)胞代謝、存活和應(yīng)激反應(yīng)的調(diào)控。它參與調(diào)節(jié)氨基酸代謝、抗氧化反應(yīng)、蛋白質(zhì)折疊和損傷修復(fù)等過(guò)程。在內(nèi)質(zhì)網(wǎng)應(yīng)激時(shí),ATF4能夠激活未折疊蛋白反應(yīng)(UPR),幫助細(xì)胞恢復(fù)蛋白質(zhì)穩(wěn)態(tài)。此外,ATF4還參與調(diào)節(jié)細(xì)胞周期、細(xì)胞凋亡以及自噬等過(guò)程,影響細(xì)胞的命運(yùn)。ATF4的功能異常與多種疾病相關(guān),包括代謝性疾病、神經(jīng)退行性疾病和某些類型的癌癥,因此,它也是藥物開(kāi)發(fā)中的一個(gè)潛在靶點(diǎn)。
