摘要:
随着后基因组学研究的逐步深入,非编码RNA成为生物学研究的热点之一,其中对mRNA非翻译区的功能研究也逐渐广泛。mRNA 非翻译区(UTR)的调控序列与一些蛋白质特异结合,对其自身mRNA命运进行调控。表皮生长因子受体(EGFR)是细胞信号转导的关键因子,其特异酪氨酸残基发生磷酸化,可招募诸如Shc、Grb2、磷脂酶Cγ和Src等信号蛋白,进而激活下游信号通路,研究证实EGFR与一些癌症的发生相关,因此探讨EGFR 非翻译区对其mRNA的调控机制就显得尤为重要。运用亲和沉降及质谱,从HeLa细胞中分离到3种蛋白质与EGFR 3 UTR相结合:Ilf3、hnRNP A1和hnRNP A2/B1。这些蛋白质均为RNA结合蛋白并参与mRNA代谢。这为研究EGFR 3 UTR的调控机制提供了依据。
