在信使RNA(mRNA)输出到细胞质后的聚腺苷酸尾伸长称为细胞质聚腺苷酸化。它首先在卵母细胞和胚胎中发现,在减数分裂和发育中发挥作用。然而,近年来,它还参与了许多其他过程,包括突触可塑性和有丝分裂。这篇综述的目的是介绍细胞质聚腺苷酸化的因素和元素介导这一过程中的不同的mRNA和不同的动物物种的重点。我们将讨论在mRNA的3′非翻译区中介导胞质聚腺苷酸化的RNA序列元件,包括CPE、MBE、TCS、eCPE和C-CPE。除了描述一般多聚腺苷酸化因子的作用外,我们还讨论了与细胞质多聚腺苷酸化元件相关的特异性RNA结合蛋白家族,包括CPEB。(CPEB 1、CPEB 2、CPEB 3和CPEB 4)、Pumilio(Pumilio 2)、Musashi(MSI 1、MSI 2)、受精卵停滞(ZAR 2)、ELAV样蛋白(ELAVL 1、HuR)、聚(C)结合蛋白(PCBP 2、α CP 2、hnRNP-E2)和双尾C(BICC 1)。一些新出现的主题在细胞质聚腺苷酸化将突出。为了便于在不同生物体和领域工作的人,特别是那些分析高通量数据的人的理解,全文使用人类直系同源物的HUGO基因命名法。在尚未明确鉴定人直系同源物的情况下,参考在人中鉴定的蛋白质家族。
Poly(A) tail elongation after export of an messenger RNA (mRNA) to the cytoplasm is called cytoplasmic polyadenylation. It was first discovered in oocytes and embryos, where it has roles in meiosis and development. In recent years, however, has been implicated in many other processes, including synaptic plasticity and mitosis. This review aims to introduce cytoplasmic polyadenylation with an emphasis on the factors and elements mediating this process for different mRNAs and in different animal species. We will discuss the RNA sequence elements mediating cytoplasmic polyadenylation in the 3′ untranslated regions of mRNAs, including the CPE, MBE, TCS, eCPE, and C-CPE. In addition to describing the role of general polyadenylation factors, we discuss the specific RNA binding protein families associated with cytoplasmic polyadenylation elements, including CPEB (CPEB1, CPEB2, CPEB3, and CPEB4), Pumilio (PUM2), Musashi (MSI1, MSI2), zygote arrest (ZAR2), ELAV like proteins (ELAVL1, HuR), poly(C) binding proteins (PCBP2, αCP2, hnRNP-E2), and Bicaudal C (BICC1). Some emerging themes in cytoplasmic polyadenylation will be highlighted. To facilitate understanding for those working in different organisms and fields, particularly those who are analyzing high throughput data, HUGO gene nomenclature for the human orthologs is used throughout. Where human orthologs have not been clearly identified, reference is made to protein families identified in man. © 2013 John Wiley & Sons, Ltd.
