应激颗粒(SG)和加工体(PB)是非膜封闭的RNA颗粒,其动态地将无活性的信使核糖核蛋白颗粒(mRNP)隔离到与周围细胞质不同的隔室中。mRNP重塑、沉默和/或储存涉及闭环聚腺苷酸化mRNP动态分配到SG中,或脱腺苷酸化线性mRNP螯合到PB中。当应激激活的途径停止翻译起始但允许正常发生延伸和终止时,形成SG,导致mRNP突然过量,其通过蛋白质:蛋白质、蛋白质:RNA和RNA:RNA相互作用在空间上浓缩成离散的焦点。相比之下,PB可以在没有应激的情况下存在,当特定因子促进mRNA去腺苷化、缩合和从翻译机器中隔离时。SG和PB的形成和溶解反映了信使RNA(mRNA)代谢的变化,并允许细胞在不断变化的环境条件下调节蛋白质组和/或介导生死决定。
Stress granules (SGs) and processing bodies (PBs) are non-membrane-enclosed RNA granules that dynamically sequester translationally inactive messenger ribonucleoprotein particles (mRNPs) into compartments that are distinct from the surrounding cytoplasm. mRNP remodeling, silencing, and/or storage involves the dynamic partitioning of closed-loop polyadenylated mRNPs into SGs, or the sequestration of deadenylated, linear mRNPs into PBs. SGs form when stress-activated pathways stall translation initiation but allow elongation and termination to occur normally, resulting in a sudden excess of mRNPs that are spatially condensed into discrete foci by protein:protein, protein:RNA, and RNA:RNA interactions. In contrast, PBs can exist in the absence of stress, when specific factors promote mRNA deadenylation, condensation, and sequestration from the translational machinery. The formation and dissolution of SGs and PBs reflect changes in messenger RNA (mRNA) metabolism and allow cells to modulate the proteome and/or mediate life or death decisions during changing environmental conditions.
