Fragile X syndrome is a genetic disorder characterized by a spectrum of physical and behavioral features and is a frequent form of inherited mental retardation (1). X-linked FMRP (FMR-1) and its two autosomal homologs, FXR1 and FXR2, are polyribosome-associated RNA-binding proteins that are involved in the pathogenesis of fragile X syndrome (1-3). Each of the fragile X proteins can self-associate, as well as form heteromers with the other two related proteins (3). FMRP can act as a translation regulator and is a component of RNAi effector complexes (RISC), suggesting a role in gene silencing (4). The Drosophila homolog of FMRP (dFMRP) associates with Argonaute 2 (Ago2) and Dicer and can coimmunoprecipitate with miRNA and siRNA (5). These results suggest that fragile X syndrome is related to abnormal translation caused by defects in RNAi-related pathways. In addition, FMRP, FXR1, and FXR2 are components of stress granules (SG) and have been implicated in the translational regulation of mRNAs (6).

X染色体易损综合征(Fragile X syndrome)是以一系列生理、行为学特征为特点一种遗传性紊乱,其也是常见的遗传性精神发育迟疾病(1)。X-linked FMRP (FMR-1) 和它的两个常染色体同系物 (FXR1 and FXR2) 都是多核糖体相关的RNA结合蛋白,它们都涉及到fragile X syndrome的发病机制(1-3)。每一个fragile X蛋白都能自我发生联系,也可以与其它两个相关蛋白形成异源二聚体(3)。FMRP能够作为一种翻译调节因子,同时也是RNAi因子复合物(RISC)的组成部分,研究认为该蛋白在基因沉默中发挥作用(4)。在果蝇中,dFMRP与 Argonaute 2 (Ago2)、Dicer和miRNA及siRNA免疫共沉淀物相联系(5)。这些研究结果认为X染色体易损综合征是和由RNAi相关通路的缺陷而引起非正常的蛋白质翻译相关。此外,FMRP、FXR1和FXR2是应激颗粒(SG)组成成员,同时这些蛋白也涉及到mRNAs翻译的调节(6)。
