载脂蛋白B(apoB)mRNA编辑是在脊椎动物中描述的第一个RNA编辑实例。apoB mRNA编辑的亚细胞定位已在大鼠肝脏中进行了检查。然而,体内的情况要复杂得多,因为锚定序列的存在不一定与其上游C的编辑有关。1997年,当研究人员在小鼠中过度表达apobec-1时,发现一种新的mRNA,NAT 1,被编辑。许多研究者已经注意到apobec-1与胞苷/胞苷酸脱氨酶的进化关系。本章概述了一些突出的点apobec-1相关的脱氨酶基因家族的进化,考虑到一些新的同源序列发表较早。基于该领域的现有知识,提出了apoB mRNA编辑酶复合物的模型。在肝脏中仅部分抑制编辑活性的动物中存在脂蛋白表型效应,与在肝脏或小肠中不编辑apoB mRNA的apobec-1敲除小鼠中相对缺乏效应形成鲜明对比。
Apolipoprotein B (apoB) mRNA editing was the first instance of RNA editing described in vertebrates. The subcellular location for apoB mRNA editing has been examined in rat liver. The situation in vivo, however, is much more complex, because the presence of the mooring sequence is not necessarily associated with editing of its upstream C. When researchers in 1997 overexpressed apobec-1 in mice, a novel mRNA, NAT1, was found to be edited. The evolutionary relationship of apobec-1 with the cytidine/cytidylate deaminases has been noted by a number of investigators. This chapter outlines a few salient points concerning the evolution of the apobec-1-related deaminase gene family, taking into consideration some novel homologous sequences published earlier. Based on the current knowledge of the area, a model of the apoB mRNA editing enzyme complex is presented. The presence of a lipoprotein phenotypic effect in animals with only partial inhibition of editing activity in the liver contrasts sharply with the relative lack of an effect in apobec-1 knockout mice that do not edit apoB mRNA either in the liver or the small intestine.
