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)。
