Cell migration plays an important role in many normal and pathological functions such as development, wound healing, immune defense, and tumor metastasis. Polarized migrating cells exhibit asymmetric distribution of many cytoskeletal proteins, which is believed to be critical for establishing and maintaining cell polarity and directional cell migration. To target these proteins to the site of function, cells use a variety of mechanisms such as protein transport and messenger RNA (mRNA) localization-mediated local protein synthesis. In contrast to the former which is intensively investigated and relatively well understood, the latter has been understudied and relatively poorly understood. However, recent advances in the study of mRNA localization and local translation have demonstrated that mRNA localization and local translation are specific and effective ways for protein localization and are crucial for embryo development, neuronal function, and many other cellular processes. There are excellent reviews on mRNA localization, transport, and translation during development and other cellular processes. This review will focus on mRNA localization-mediated local protein biogenesis and its impact on somatic cell migration.
细胞迁移在许多正常和病理功能中发挥着重要作用,如发育、伤口愈合、免疫防御和肿瘤转移。极化迁移细胞表现出许多细胞骨架蛋白的不对称分布,这被认为对于建立和维持细胞极性以及细胞定向迁移至关重要。为了将这些蛋白质靶向到功能位点,细胞使用多种机制,如蛋白质运输和信使核糖核酸(mRNA)定位介导的局部蛋白质合成。与前者被深入研究且相对了解较多不同,后者的研究较少且相对了解不足。然而,mRNA定位和局部翻译研究的最新进展表明,mRNA定位和局部翻译是蛋白质定位的特定有效方式,对胚胎发育、神经元功能和许多其他细胞过程至关重要。关于发育和其他细胞过程中mRNA定位、运输和翻译已有优秀的综述。本综述将聚焦于mRNA定位介导的局部蛋白质生物合成及其对体细胞迁移的影响。
