Description

经改造的Cas9蛋白及其用途
技术领域
本发明涉及维持了与向导RNA结合的能力且小型化的经改造的Cas9蛋白及其用途。
背景技术
已知成簇的规律性间隔的短回文重复序列(Clustered Regularly InterspacedShort Palindromic Repeats:CRISPR)与Cas(CRISPR相关)基因一起构成细菌及古细菌中提供对入侵外源核酸的获得性抗性的适应性免疫系统。CRISPR大多起源于噬菌体或质粒DNA,由在其间插入了尺寸相似的被称为间隔子的独特的可变DNA序列的、24~48bp的短的保守重复序列构成。另外,在重复序列及间隔子序列附近存在编码Cas蛋白家族的基因群。
CRISPR/Cas系统中,外源性DNA被Cas蛋白家族切成30bp左右的片段并被插入到CRISPR中。作为Cas蛋白家族之一的Cas1及Cas2蛋白识别外源性DNA的被称为前间隔序列邻近基序(proto-spacer adjacent motif,PAM)的碱基序列,切取其上游并插入到宿主的CRISPR序列中,其形成细菌的免疫记忆。转录包含免疫记忆的CRISPR序列而生成的RNA(称为pre-crRNA。)与部分互补的RNA(trans-activating crRNA:tracrRNA)配对,整合到作为Cas蛋白家族之一的Cas9蛋白中。整合到Cas9中的pre-crRNA及tracrRNA被RNaseIII切断,成为包含外源序列(向导序列)的小的RNA片段(CRISPR-RNAs:crRNAs),形成Cas9-crRNA-tracrRNA复合物。Cas9-crRNA-tracrRNA复合物结合到与crRNA互补的外源入侵DNA上,作为切断DNA的酶(nuclease)的Cas9蛋白将外源入侵DNA切断,由此抑制和消除从外部入侵的DNA的功能。
近年来,正在积极开发将CRISPR/Cas系统应用于基因组编辑的技术。使crRNA和tracrRNA融合而以tracrRNA-crRNA嵌合体(以下称为向导RNA(guide RNA:gRNA)。)形式表达,并有效利用。由此引进核酸酶(RNA-guided nuclease:RGN)并在目标位点切断基因组DNA。
另一方面,通过在作为基因组编辑系统之一的CRISPR/Cas9中的Cas9蛋白的核酸酶已失活的变异体(nuclease-null,dCas9)中融合VP64、VP160等转录活化因子或KRAB等转录抑制因子等转录调控因子,从而能够形成能调节靶基因的表达水平的系统。例如,为了进一步提高基因活化的效率而与将2个转录活性因子连接而成的活化因子(VP64-Rta)、将3个转录活性因子连接而成的活化因子(VP64-p65-Rta,VPR)融合,该融合而得的dCas9蛋白(dCas9-VPR;dCas9融合蛋白)在不切断DNA的情况下强烈活化靶基因的表达。
对于Cas9蛋白,以PAM特异性的缓和、核酸酶活性的改造(活化/失活)、小型化为目的,已研制并报道了各种变异体(专利文献1~3)。

发明内容
发明所要解决的问题
在体内的dCas9融合蛋白的表达中,需要表达载体。基因治疗中,从安全性和效率高角度来看,腺相关病毒载体(AAV)逐渐成为主流,但是AAV的可搭载的尺寸为4.4kb左右,而dCas9蛋白已占据4kb左右,搭载于AAV中时,融合蛋白的构成极其受限。
因此,本发明人的目的在于,提供具有与全长蛋白质实质上同等的DNA结合亲和性且进一步小型化的dCas9蛋白的变异体。
用于解决问题的方法
本发明人着眼于作为Cas9蛋白的源自金黄色葡萄球菌(S.aureus)的Cas9(本说明书中也称为SaCas9)的无核酸酶(nuclease-null)变异体(dSaCas9),为了解决上述问题进行了深入研究。结果发现了即使发生缺失也较少影响与向导RNA结合的能力的特定区域,进而通过将规定位置的氨基酸置换为特定氨基酸,成功地制造出DNA结合亲和性得到了维持、甚至增强且小型化的dSaCas9蛋白,从而完成了本发明。
将缺失及置换一并称为变异。

<用于对靶双链多核苷酸进行位点特异性改造的方法>
[第一实施方式]
一个实施方式中,本发明提供用于对靶双链多核苷酸进行位点特异性改造的方法,所述方法具备:
将靶双链多核苷酸、蛋白质和向导RNA混合并进行温育的步骤;和上述蛋白质在位于PAM序列的上游的结合位点处对上述靶双链多核苷酸进行改造的步骤,
上述靶双链多核苷酸具有PAM序列,
上述蛋白质为上述的<dSaCas9变异体>中所示的蛋白质,
上述向导RNA包含下述多核苷酸,所述多核苷酸由与上述靶双链多核苷酸中的上述PAM序列的上游1个碱基至上游20个碱基以上且24个碱基以下的碱基序列互补的碱基序列构成。
本实施方式中,靶双链多核苷酸只要具有PAM序列即可,没有特别限定。
本实施方式中,关于蛋白质及向导RNA,如上述的<dSaCas9变异体>中所示。
以下对用于对靶双链多核苷酸进行位点特异性改造的方法进行详细说明。
首先,将上述蛋白质及上述向导RNA在温和的条件下混合并进行温育。温和的条件如上所述。进行温育的时间优选为0.5小时以上且1小时以下。由上述蛋白质及上述向导RNA形成的复合物稳定,在室温下静置数小时也能够保持稳定性。
然后,上述蛋白质及上述向导RNA在上述靶双链多核苷酸上形成复合物。上述蛋白质识别PAM序列并在位于PAM序列的上游的结合位点处与上述靶双链多核苷酸结合。接着,可以得到在通过上述向导RNA与上述双链多核苷酸的互补性结合而确定的区域中实施了目标改造的靶双链多核苷酸。
本说明书中,“改造”是指靶双链多核苷酸结构上或功能上发生变化。可列举例如通过添加功能性蛋白质、碱基序列而进行的靶双链多核苷酸的结构上或功能上的变化。通过该改造,能够使靶双链多核苷酸的功能发生改变、缺失、增强或抑制而添加新功能。
本发明的dSaCas9变异体不具有内切核酸酶活性,因此该蛋白质能够在位于PAM序列的上游的结合位点处与上述靶双链多核苷酸结合,但止步于此,不会将其切断。因此,例如预先在该蛋白质上融合荧光蛋白(例如GFP)等标记蛋白时,可以介由dSaCas9变异体蛋白-向导RNA使标记蛋白与靶双链多核苷酸结合。通过适宜地选择与dSaCas9变异体结合的物质,能够给靶双链多核苷酸带来多样的功能。
进一步地,可以在dSaCas9变异体蛋白的N末端或C末端连接转录调控因子蛋白或结构域。作为转录调控因子或其结构域,可列举转录活化因子或其结构域(例如VP64、VP160、NF-κB p65)及转录沉默子或其结构域(例如异染色质蛋白1(HP1))或转录抑制因子或其结构域(例如KRUPPEL相关盒(KRAB)、ERF阻抑结构域(ERD)、mSin3A相互作用结构域(SID))。
也可以连接修饰DNA的甲基化状态的酶(例如DNA甲基转移酶(DNMT)、TET)、修饰组蛋白亚基的酶(例如组蛋白乙酰基转移酶(HAT)、组蛋白去乙酰化酶(HDAC)、组蛋白甲基转移酶、组蛋白去甲基化酶)。
[第二实施方式]
本实施方式中,在温育步骤之前可以还具备下述表达步骤:使用上述CRISPR-Cas载体系统表达上述的<dSaCas9变异体>中所示的蛋白质和向导RNA。
本实施方式的表达步骤中,首先使用上述CRISPR-Cas载体系统表达dSaCas9变异体蛋白及向导RNA。作为表达的具体方法,使用包含编码dSaCas9变异体蛋白的基因的表达载体及包含向导RNA的表达载体各载体(或同时包含编码dSaCas9变异体蛋白的基因及向导RNA的表达载体)转化宿主。接着,对该宿主进行培养,表达dSaCas9变异体蛋白及向导RNA。培养基的组成、培养的温度、时间、诱导物质的添加等条件可以按照公知的方法由本领域技术人员决定,以使转化体能够生长、高效地产生融合蛋白。另外,例如在表达载体中整合有作为选择标志物的抗生素抗性基因时,可以向培养基中加入抗生素来选择转化体。接着,通过利用适宜的方法纯化宿主所表达的dSaCas9变异体蛋白及向导RNA,可得到dSaCas9变异体蛋白及向导RNA。
<用于在细胞内对靶双链多核苷酸进行位点特异性改造的方法>
一个实施方式中,本发明提供在细胞内对靶双链多核苷酸进行位点特异性改造的方法,所述方法具备:
将上述CRISPR-Cas载体系统导入到细胞中而表达上述<dSaCas9变异体>中所示的蛋白质和向导RNA的表达步骤;
上述蛋白质在位于PAM序列的上游的结合位点处与上述靶双链多核苷酸结合的步骤;和
得到在通过上述向导RNA与上述靶双链多核苷酸的互补性结合而确定的区域中进行了改造的上述靶双链多核苷酸的步骤,
上述向导RNA包含如下多核苷酸,所述多核苷酸由与上述靶双链多核苷酸中的上述PAM序列的上游1个碱基至上游20个碱基以上且24个碱基以下的碱基序列互补的碱基序列构成。
本实施方式的表达步骤中,首先使用上述CRISPR-Cas载体系统在细胞内表达dSaCas9变异体蛋白及向导RNA。

3.基因表达分析
为了进行Taqman分析,以20μl的容量使用TaqManTM高容量RNA-to-cDNA试剂盒(Applied Biosystems)由1.5μg的总RNA制备cDNA。将制备的cDNA稀释至20倍,每个Taqman反应使用6.33μl。针对MYD88基因及HPRT基因的Taqman引物及探针由Applied Biosystems获得。在Roche LightCycler 96或LightCycler 480中,使用Taqman基因表达预混物(geneexpression master mix)(ThermoFisher)进行Taqman反应,使用LightCycler 96analysis软件进行分析。

上述结果中,特别是对于DNA结合亲和性高的T10,即使改变向导RNA也确认到其结合亲和性。利用表达pX601-dSaCas9(FL或T10)-KRAB-P2A-sfGFP及sgRNA-A2或sgRNA-A3的质粒载体转染HEK293FT细胞。使用利用不表达dSaCas9变异体的载体转染而得的细胞作为阴性对照。3天后回收所转染的细胞,单离出RNA。利用Taqman分析来分析MYD88基因的表达,利用HPRT基因的表达水平进行标准化。将MYD88基因的相对表达水平的结果示于图3。在使用sgRNA-A3的情况下也确认到与sgRNA-A2同样的效果。
本发明的dSaCas9变异体中的MYD88基因表达水平与对照相比降低至与野生型dSaCas9匹敌的程度。该结果表明,本发明的dSaCas9变异体尽管存在缺失区域、与全长的dSaCas9相比缩小,但是与向导RNA结合的能力以及DNA结合亲和性得到了维持。
产业上的可利用性
根据本发明,能够得到保持了DNA结合亲和性且小型化的dSaCas9蛋白。小型化的dSaCas9蛋白的使用使更多的基因向载体中的搭载成为可能,因此能够提供多样的基因组编辑技术。
