一般說明
无义转录本1的调节剂(UniProt:Q92900;又称ATP依赖性解旋酶RENT1,无义mRNA还原因子1,NORF1,上移码抑制因子1同源物,hUpf1)由人UPF1(又称KIAA0221,RENT1)基因(基因ID:5976)编码。Upf1是Dna2/Nam7解旋酶家族的成员。它是含有过早终止密码子的mRNA的无义介导的衰变(NMD)所需的RNA依赖性解旋酶和ATPase。它在翻译终止后被募集到mRNA,并经历磷酸化和去磷酸化的循环。它被SMG1磷酸化,磷酸化被认为是NMD中必不可少的步骤,是形成mRNA监视复合物所必需的。磷酸化的Upf1被Est1b/SMG5,SMG6和SMG7识别,它们提供了与涉及核酸外切和核酸内切途径的mRNA降解机制的联系。超磷酸化形式靶向P体,而未磷酸化的蛋白质分布在整个细胞质中。Upf1的ATPase活性是分解经历NMD的mRNP所必需的,并且对于胚胎生存能力也是必不可少的。据报道,通过选择性剪接产生了Upf1的两种亚型。Upf1包含Upf1型锌指结构域(aa 121-272)和核苷酸结合结构域(aa 506-510)。

Nonsense-mediated mRNA decay (NMD) is an evolutionarily conserved RNA decay mechanism that has emerged as a potent cell-intrinsic restriction mechanism of retroviruses and positive-strand RNA viruses. However, whether NMD is capable of restricting DNA viruses is not known. The DNA

Long-read RNA sequencing (RNA-seq) is a powerful technology for transcriptome analysis, but the relatively low throughput of current long-read sequencing platforms limits transcript coverage. One strategy for overcoming this bottleneck is targeted long-read RNA-seq for preselected gene panels. We present

Fragile X syndrome (FXS) is an intellectual disability attributable to loss of fragile X protein (FMRP). We previously demonstrated that FMRP binds mRNAs targeted for nonsense-mediated mRNA decay (NMD) and that FMRP loss results in hyperactivated NMD and inhibition of

Nonsense-mediated mRNA decay (NMD) is an mRNA degradation pathway that eliminates transcripts containing premature termination codons (PTCs). Half-lives of the mRNAs containing PTCs demonstrate that a small percent escape surveillance and do not degrade. It is not known whether this

Many gene expression factors contain repetitive phosphorylation sites for single kinases, but the functional significance is poorly understood. Here we present evidence for hyperphosphorylation as a mechanism allowing UPF1, the central factor in nonsense-mediated decay (NMD), to increasingly attract downstream
