The fate of an RNA, from its localization, translation, and ultimate decay, is dictated by interactions with RNA binding proteins (RBPs). β-actin mRNA has functioned as the classic example of RNA localization in eukaryotic cells. Studies of β-actin mRNA over the past three decades have allowed understanding of how RBPs, such as ZBP1 (IGF2BP1), can control both RNA localization and translational status. Here, we summarize studies of β-actin mRNA and focus on how ZBP1 serves as a model for understanding interactions between RNA and their binding protein(s). Central to the study of RNA and RBPs were technological developments that occurred along the way. We conclude with a future outlook highlighting new technologies that may be used to address still unanswered questions about RBP-mediated regulation of mRNA during its life cycle, within the cell.
RNA的命运，从其定位、翻译到最终降解，都由与RNA结合蛋白（RBP）的相互作用所决定。β-肌动蛋白mRNA一直是真核细胞中RNA定位的经典例子。在过去三十年里，对β-肌动蛋白mRNA的研究使人们了解了诸如ZBP1（IGF2BP1）等RBP如何控制RNA的定位和翻译状态。在这里，我们总结了对β-肌动蛋白mRNA的研究，并重点关注ZBP1如何作为理解RNA与其结合蛋白之间相互作用的模型。RNA和RBP研究的核心是在此过程中出现的技术发展。我们最后展望未来，强调可能用于解决关于细胞内RBP介导的mRNA生命周期调控中仍未解答问题的新技术。
