Abstract
本发明涉及家蚕丝素重链基因突变的方法,具体为将编码锌指核酸酶序列的mRNA作用于如SEQ.IDNO:1所示的家蚕丝素重链基因1325~1362位为锌指核酸酶识别的靶位点,得一系列家蚕丝素重链突变基因;该突变序列和用于制备丝胶蛋白和外源蛋白;1)本发明提供的丝素重链基因突变体的后部丝腺严重退化,其茧层中只含有中部丝腺中合成与分泌的丝胶蛋白,如果利用这些突变品系在家蚕后部丝腺中转基因表达外源蛋白,其表达量和纯度将会大大的提高,这为家蚕丝腺生物反应器的开发提供了一种全新的有用的遗传素材;2)本发明提供的突变品系的茧层中只有丝胶蛋白为丝胶蛋白的大规模生产提供了一种新的来源。
Description
技术领域
本发明属于家蚕育种和基因工程领域,涉及基于不同现有蚕品种的家蚕丝素重链基因突变体,及其制备方法、突变序列和用途。
背景技术
家蚕因其强大的泌丝吐丝能力而蜚声古今中外,在长达数千年的饲养和驯化中为世界经济和文化交流做出了重要的贡献,至今也仍然是中国、印度等国家产业的重要组成部分。但是长期以来人们选育家蚕品种都是以茧层量、茧层率、解舒和抗病性的提高作为育种目标,而忽略了茧丝强度、延伸性、染色性能、肌肤亲和性等重要指标。这也是蚕丝难以像蜘蛛丝等高强度纤维那样广泛的应用于医学、军事等高端领域,而仅仅只是作为单一的纺织材料的主要原因。因此,如何快速的育成高茧丝强度、强延伸性、易染色、高肌肤亲和性等优质的蚕丝显得尤为重要。
家蚕经过数千年的选育,虽然目前品种资源较为丰富,但就茧丝强度、延伸性、染色性能、肌肤亲和性等特性而言,品种间几乎没有什么差异,所以通过传统育种方法改变蚕丝的这些特性基本上不可行。随着家蚕基因组计划的全面完成,分子标记辅助育种、转基因育种等现代农业的新型工具逐渐的加入家蚕品种分子改良的主力阵容之中。家蚕丝蛋白只要由丝素重链、丝素轻链和P25蛋白及包裹的在最外层的丝胶蛋白组成,其中决定茧丝性能的丝素重链蛋白是一个由高度重复序列构成的大约390kDa的蛋白。丝素重链蛋白的高表达量、高度重复序列和高分子量使得用常规的转基因技术也难以对其进行研究和改造。
此外,一头体重约为6g的家蚕食下25g左右的桑叶,便能吐出0.5g由纯蛋白组成的蚕丝,这不仅是让人叹为观止的生物学奇观,其中更是蕴藏着令人无限憧憬的应用价值。不仅如此,家蚕丝腺还具有高等生物蛋白质的翻译后修饰加工能力、大规模生产成本低以及对人畜安全性等优势,满足了新一代生物反应器的基本要求,有巨大的开发应用潜力。该领域研究已成为由传统蚕丝产业向非绢丝产业拓展的重要内容。无论是在基础研究,还是在药物、化妆品开发领域,提取或表达纯化的蛋白都扮演着极其重要的角色,但是商业化蛋白纯品高得离奇的价格(1g最常用的绿色荧光蛋白价格约5百万元)一直在困扰着众多研究者们。大规模表达或提取蛋白的工艺的缺乏严重的制约着与蛋白相关的研究和产品的发展。饲养一头蚕的成本不足1角钱,却能吐0.5g的丝蛋白,而如果能用基因工程手段让家蚕吐出0.5g纯蛋白,这对于蚕丝产业、甚至生物产业都将产生革命性的推动作用。也正是这一奇特的生物学现象和应用前景吸引着众多生物学家自分子生物学发端以来就长期致力于家蚕丝蛋白的表达调控和家蚕生物反应器的开发。然而,要实现这一看似简单而美好的梦想并非易事。尽管通过长达数十年的探索与研究,家蚕丝蛋白基因的表达调控机理还不尽清楚,丝腺生物反应器开发的道路更是尽显曲折而收效甚微。虽然研究者们利用家蚕丝蛋白基因的启动子先后在家蚕丝腺的不同部位成功的表达了绿色荧光蛋白、红色荧光蛋白、胶原蛋白、人碱性成纤维细胞生长因子、猫干扰素、植酸酶、人血清白蛋白、鼠单克隆抗体、蜘蛛牵引丝蛋白和人脑源神经营养因子等具有重大研究和应用价值的蛋白。但是目前家蚕丝腺中转基因表达的外源活性蛋白最高只能达到蚕茧总重量的8.0%。表达量太低,从茧层中纯化少量蛋白的工艺成本太高,令试图进一步开发家蚕丝腺生物反应器学者和商家们都望而止步。
不论是对于家蚕丝蛋白本身的改良,还是开发实用、高效的家蚕丝腺生物反应器,找到一种能有效定点改造家蚕丝蛋白基因的方法或者快速育成丝蛋白突变体资源都显得尤为重要和紧迫。然而,尽管学者们在家蚕基因打靶方面也进行了一些探索,但是目前还没有一种可用的家蚕基因组定向改造技术。
锌指核酸酶是一种人工设计的限制酶,由负责特异性识别DNA序列的锌指蛋白结构域和负责切割DNA的核酸酶结构域组成。锌指核酸酶能在复杂基因组里的特定位点造成双链断裂。从而刺激机体的DNA修复系统:非同源末端连接(NHEJ, Non-homologous End Joining)和同源重组(HR,Homologous
recombination)。NHEJ是一种特殊的DNA双链断裂修复机制,其在不存在DNA同源序列的情况下快速、高效的强行将断裂的DNA末端连接在一起,这是一种不忠实的修复机制,容易在修复处引入少数碱基的缺失、插入或突变;如果在同一DNA大片段中设计两对锌指核酸酶,也可能会造成两个识别位点之间的大片段缺失;此外,在存在与断裂末端具有相同粘性末端的外源DNA的情况下,NHEJ还可以实现特定小片段的插入。HR是机体内常见的一种DNA断裂修复机制,其原理自上世纪80年代以来已经广泛的被应用于基因敲除中。通过人为设计各种不同类型的供体质粒,借助锌指核酸酶介导的双链断裂,可以高效的对靶标基因进行定点置换、修复、删除、插入等任意的操作。目前,这一技术已被广泛的应用于动植物的基因敲除和定点改造之中。
发明内容
本发明的目的之一在于提供一种家蚕丝素重链基因的突变方法和该突变方法得到的基因序列,该方法为获得突变的家蚕丝素重链基因提供了新思路。
为实现上述目的,本发明的技术方案为:
家蚕丝素重链突变基因,所述家蚕丝素重链突变基因为家蚕丝素重链基因1325~1362位为锌指核酸酶识别的靶位点的突变基因。
所述家蚕丝素重链突变基因如SEQ.ID NO:2-118中任一种所示。
所述家蚕丝素重链突变基因如SEQ.ID NO:2-14中任一种所示。
所述家蚕丝素重链突变基因如SEQ.ID NO:11所示。
家蚕丝素重链基因的突变方法,将含有如SEQ.ID NO:119和SEQ.ID NO:120所示锌指核酸酶序列的插入到含有T7:5’-taatacgactcactataggg-3’或SP6:5’-atttaggtgacactatag-3’启动子的原核表达载体中,获得重组载体;将重组载体进行体外转录,获得编码锌指核酸酶序列的mRNA,将编码锌指核酸酶序列的mRNA作用于如SEQ.ID NO:1所示的家蚕丝素重链基因1325~1362位为锌指核酸酶识别的靶位点,得家蚕丝素重链突变基因。
本发明的目的之二在于提供两种家蚕丝素重链突变基因的新应用,该应用为制备丝胶蛋白和外源蛋白提供了有效途径。
所述的家蚕丝素重链突变基因在制备内源蛋白中的应用。
所述的家蚕丝素重链突变基因在制备丝胶蛋白中的应用。
所述的家蚕丝素重链突变基因在制备外源蛋白中的应用。
本发明的有益效果在于:
本发明利用新近发展起来的锌指核酸酶技术,高效的对家蚕丝素重链基因进行了敲除,首次获得了包括在丝素重链基因N端非重复区域部分缺失、部分碱基突变或小片段插入的一系列突变家蚕品系。本发明提供的这些突变体具有如下的特点及优势:1)本发明提供的丝素重链基因突变体的后部丝腺严重退化,其茧层中只含有中部丝腺中合成与分泌的丝胶蛋白,如果利用这些突变品系在家蚕后部丝腺中转基因表达外源蛋白(如蜘蛛丝、生物活性蛋白等),外源蛋白在家蚕丝腺中的表达量和纯度将会大大的提高,这为家蚕丝腺生物反应器的开发提供了一种全新的有用的遗传素材;2)由于本发明提供的突变品系的茧层中只有丝胶蛋白,而纯丝胶蛋白目前已经广泛的被用于化妆品,本发明为丝胶蛋白的大规模生产提供了一种新的来源。
