Eucaryotic messenger RNA precursors are processed in nuclear ribonucleoprotein particles (hnRNP). Here recent work on the structure of hnRNP is reviewed, with emphasis on function. Detailed analysis of a specific case, the altered assembly of hnRNP in heat-shocked Drosophila and mammalian cells, leads to a general hypothesis linking hnRNP structure and messenger RNA processing.
真核生物信使核糖核酸前体在核糖核蛋白颗粒(hnRNP)中进行加工。本文综述了hnRNP结构的近期研究工作,重点是其功能。对一个特定案例——热休克果蝇和哺乳动物细胞中hnRNP组装改变的详细分析,得出了一个将hnRNP结构与信使核糖核酸加工联系起来的一般性假说。
