Upf1 was identified as an active component in nonsense-mediated decay (NMD), an mRNA surveillance mechanism in eukaryotic cells that degrades mRNAs containing premature termination codons (1). Upf1 was found to be an ATP-dependent RNA helicase in the cytoplasm (2) and was later shown to be a component of cytoplasmic P-bodies (3). Upf1 phosphorylation mediates the repression of translation that accompanies NMD, allowing mRNA accessibility to the NMD machinery (4). Two other active components of NMD, Upf2 and Upf3, were also identified and described as having perinuclear and nucleocytoplasmic localization, respectively (5).

Upf1蛋白被确认是无义介导的降解(NMD)中的一个活性组分,NMD是真核细胞中mRNA的一种监控机制,能够降解含有提前终止密码子的mRNA(1)。研究发现,Upf1蛋白是胞质中一个ATP依赖的RNA解旋酶(2),后来发现它还是细胞质加工小体(cytoplasmic P-bodies)中的一个成分(3)。Upf1蛋白的磷酸化能够介导翻译抑制,其伴随着NMD作用,因而允许mRNA更易进入NMD机制(4)。此外,还鉴定出了NMD的另外两个活化分子,Upf2和Upf3。分别定位于核周以及核质(5)。
