Description

基于CjCas9和VPR核心结构域的融合蛋白、相应的DNA靶向激活系统及其应用

技术领域

本发明属于生物技术领域，涉及一种基于CjCas9及其突变体和VPR核心结构域的融合蛋白、相应的DNA靶向激活系统及其应用。

背景技术

CRISPR/Cas9系统是目前应用广泛的基因编辑系统，是从细菌和古细菌降解外源DNA的适应性免疫机制改造而来。CRISPR/Cas9系统主要包含两个元件：Cas9蛋白和向导RNA。Cas9蛋白和向导RNA结合后会在向导RNA的引导下对特定位点DNA双链进行切割，从而产生断裂，这比之前的基因编辑方法要简单得多。而近年来，CRISPR/Cas9系统也逐渐应用于基因调节领域。利用失去切割活性的CRISPR/Cas9系统并结合转录激活或者抑制因子，也可以在真核以及原核生物激活或抑制基因的表达，这些使CRISPR系统可能成为下一基因治疗的有利平台。

CjCas9来源于空肠弯曲菌，与其他CRISPR系统相比，它具有以下优势：首先，PAM区不同。CRISPR系统对DNA的靶向受到PAM区的限制，CjCas9的PAM区为NNNVRYAC,不同于SpCas9识别G-rich PAM，Cpf1复合物识别的T-rich PAM序列,这为CRISPR系统的编辑位点提供了更多的选择。其次，特异性不同。相对于SpCas9具有较高的脱靶率，CjCas9具有更高的特异性。更重要的是，大小不同。CjCas9是目前已知的最小的Cas9蛋白，相比于SpCas9有1368个氨基酸，CjCas9只有984个氨基酸，更容易进入组织和细胞，这极大地拓展了CRISPR系统在体内外的应用。

VPR是三种转录激活因子vp64、p65和rta的核心结构域组成的融合蛋白。一方面，它具有这三种转录激活因子的协同作用，使其能在更多的位点实现更好的激活效果。另外一方面，它是由这三种转录激活因子的核心结构域组成的融合蛋白，长度仅325个氨基酸，提高了它的应用范围。

目前，CRISPR/Cas9系统对基因的调控主要应用于体外，而在体内应用较少，其原因有很多，其中最重要的是大部分Cas9蛋白较大，超过了一些包装方法如AAV病毒的包装范围，再结合转录调节系统，更是超过了大部分包装系统的容量，使得调节系统很难传递到体内的组织细胞发挥作用。同时基因调节的效果以及系统的特异性也是其局限因素。在本发明中，将目前体积最小的CjCas9蛋白和三种转录激活因子vp64、p65和rta的核心结构域组成的融合蛋白VPR结合，整个激活系统具有小体积、强激活效果以及高特异性。可以通过一些常用的包装方法如AAV病毒传递至体内，发挥其激活效果。

发明内容

本发明目的在于：针对已有基因激活方法靶向性低，激活效率低，以及系统体积过大难以应用于体内等问题，将目前体积最小的CRISPR/Cas9系统蛋白CjCas9和转录激活因子VPR结合，提供一种体积小、激活效果强以及高特异性的激活系统，可以实现体内外高效的基因激活。

为了实现上述发明目的，本发明提供了一种融合蛋白，包括两个异源多肽结构域，其中一个多肽结构域包含具有转录激活活性的VPR蛋白，所述VPR蛋白由三种转录激活因子vp64、p65、rta的核心结构域组成；另一种多肽结构域包含CjCas9蛋白，所述CjCas9蛋白为dCjCas9亚型、mini-dCjCas9亚型或CjCas9野生型。所述的CjCas9野生型为目前现有的亚型，序列如SEQ ID NO：3中倾斜字体所示；所述dCjCas9亚型是本发明基于CjCas9野生型在D8A和H559A单位点氨基酸突变，使CjCas9野生型无酶切割活性有靶向基因识别特性，序列如SEQ ID NO：1中倾斜字体所示；所述mini-dCjCas9亚型是本发明基于CjCas9野生型在D8A单位点氨基酸突变以及大部分HNH结构域(△495-601氨基酸)的缺失，序列如SEQ ID NO：2中倾斜字体所示。(除了野生型，其他都是之前没有的)。

一种表达载体，该表达载体用于表达上述所述的融合蛋白。

进一步地，所述表达载体的启动子为CMV，入核信号为SV40 NLS，VPR蛋白和CjCas9蛋白之间插入一段连接序列linker，序列如SEQ ID NO：1中加粗字体所示。

一种DNA靶向激活系统，包括上述所述的融合蛋白和至少一种向导RNA，所述向导RNA包含针对目的基因启动子区域设计的一段长度为14bp-22bp的序列和一段80bp的骨架序列。

进一步地，VPR与dCjCas9亚型、mini-dCjCas9亚型或CjCas9野生型的融合蛋白均可实现基因的激活，其中VPR与dCjCas9亚型的融合蛋白具有相对更高的激活效率；VPR与mini-dCjCas9亚型的融合蛋白更小，在动物体内应用中具有更好的前景；VPR与CjCas9野生型融合蛋白可利用15bp和22bp的导向gRNA，同时进行基因激活和切割；同时，本发明还基于VPR与mini-dCjCas9亚型的融合蛋白，将转录因子VPR中的vp64进行密码子优化，VPR整体缩小27个氨基酸序列，VPR与mini dCjCas9之间的linker缩小33个氨基酸，使得整个激活系统更小，融合蛋白的表达量更强。

进一步地，所述CjCas9的向导RNA骨架序列包含两种，一种是已知的骨架序列WT向导RNA骨架，其核苷酸序列如SEQ ID NO：9所示；另一种是含有T5A和A24T单位点碱基突变的F向导RNA骨架，其核苷酸序列如SEQ ID NO：10所示。

现有技术中只有利用野生型CjCas9加22bp导向RNA做基因切割，没有人利用CjCas9做过激活。本申请1、把野生型CjCas9突变为dCjCas9，然后与之前有的VPR结合用于激活；2、把野生型CjCas9突变并缩短为mini-dCjCas9，也可以实现激活，同时因为删减质粒更小，体内应用范围更广；3、直接利用野生型CjCas9，发现结合15bp的导向RNA，也可以实现激活，而且还可以结合靶向其他基因22bp的导向，可以实现对一个基因激活的同时实现对其他基因的切割；4、将VPR与mini-dCjCas9的融合蛋白进一步缩减优化，VPR缩小，linker缩小，整个蛋白更小，同时因为对Vp64密码子优化，使得这个融合蛋白翻译效率更高，表达量更强；5、向导RNA骨架序列：WT向导RNA骨架是之前有的，将T5A和A24T单位点碱基突变的F向导RNA骨架是本申请改进的，改进之后激活效果更好。

上述所述的DNA靶向激活系统在进行基因的靶向激活中的应用。

进一步地，所述靶向基因为活体动物基因。本发明提供的DNA靶向激活系统可以高效激活基因的表达，具体包括如下步骤：(1)构建CjCas9和VPR核心结构域的融合蛋白表达载体；(2)构建表达特定向导RNA的载体；(3)将步骤(1)所述融合蛋白表达载体和步骤(2)所述表达特定向导RNA的载体混合，通过脂质体转染试剂聚乙烯亚胺(PEI)共转染到哺乳动物细胞，在细胞内表达的融合蛋白与其向导RNA结合，将转录激活因子VPR靶向目标基因区；(4)48h后提取mRNA，检查目标基因mRNA表达水平；再通过全转录水平mRNA测序，分析靶向激活结果和特异性水平。

与现有技术相比，本发明的优势在于：本发明提供的DNA靶向激活系统具有体积小特异性高，激活效果强易于合成，成本低等优点。因此，本发明方法不仅可以与已有的基因激活方法相互补充，同时因为其独特的优势，更利于动物体内的应用，为CRISPR/Cas9系统的基因治疗、肿瘤治疗等提供了新的应用前景，具有潜在的重要经济价值和意义。
