背景(Background)
簇集蛋白(Clusterin,CLU)也稱為二聚酸性糖蛋白(DAG蛋白)、睪酮抑制前列腺信息-2(TRPM-2)、硫酸化糖蛋白-2(SGP-2)和補體裂解抑制劑(CLI),是一種分泌型多功能糖蛋白,屬于簇集蛋白家族。簇蛋白前體的細胞內(nèi)裂解會去除信號肽,并產(chǎn)生大小相當?shù)?/span>α和β鏈,這些鏈以80 kDa N糖基化二硫鍵連接的異二聚體的形式分泌。DAG蛋白主要在成年睪丸、卵巢、腎上腺、肝臟、心臟和大腦以及胚胎發(fā)育過程中的許多上皮組織中表達。聚簇蛋白涉及幾個基本的生物學事件,如細胞死亡、腫瘤進展和神經(jīng)退行性疾病。在不同疾病狀態(tài)和體外系統(tǒng)中檢測到的簇集蛋白mR和蛋白質(zhì)水平的上調(diào)表明,它在膜脂質(zhì)循環(huán)、凋亡細胞死亡以及作為應(yīng)激誘導的分泌伴侶蛋白等方面發(fā)揮作用。
