专利名称:石斑鱼胰岛素样生长因子Ⅰ受体基因及其应用的制作方法
技术领域
本发明属于基因工程技术领域,具体地说涉及一种基因。
背景技术
胰岛素样生长因子(IGFs)是一类多功能的细胞增殖因子,具有广泛的生物学效应,在胚胎和个体发育过程中起着重要作用。IGFs通过细胞表面两种类型的IGF受体发挥生物学作用。IGFs受体有两种,分别称为IGF-I受体(IGF-IR或称I型IGF受体)和IGF-II受体(IGF-IIR或称II型IGF受体)。IGFs对细胞的作用绝大多数都是通过与IGF-IR结合而实现的。IGF-IR为四聚体糖蛋白,由2个位于细胞外部的α亚基和2个跨膜β亚基组成。IGF-IR的结构与胰岛素受体极其相似。α亚基的半胱氨酸富集区是其配体的特异识别位点,细胞质部分的β链含有一个酪氨酸激酶活性区。一个α亚基和一个β亚基由二硫键连接起来形成一个半受体,两个半受体由α亚基上的二硫键构成一个完整的受体。IGF-I与IGF-IR结合会引发受体上位于细胞内的β亚基上的酪氨酸和丝氨酸残基的磷酸化,进而导致一系列的生物学效应。IGFs在鱼类的生长繁殖上起着重要作用,而仅仅对IGFs的研究是不足的,应该进一步了解IGFs与其受体的相互作用,这对于认识IGF的分子作用机理具有重要意义。而现有技术中,对IGFs受体的研究主要集中在哺乳动物中,对于鱼类的IGFs受体的研究很少。
石斑鱼是海洋珊瑚礁鱼类,属鮨科(Serranidae),石斑鱼属(Epinephelus),有30多种。石斑鱼是一种名贵的海水鱼类,具有极高的经济价值。石斑鱼的苗种培育是养殖生产持续发展的关键,但目前在石斑鱼人工养殖中还没有一种能有效促进其苗种生长的饵料添加剂。

发明内容
本发明的目的在于针对目前石斑鱼的苗种培育问题,提供一种重组石斑鱼胰岛素样生长因子I受体基因,利用该基因可以生产重组石斑鱼胚胎期胰岛素样生长因I受体蛋白,该受体蛋白能够有效促进石斑鱼苗种的生长,在制备鱼苗促生长剂或添加剂中有着重要的应用。
本研究对斜带石斑鱼IGFs受体的cDNA进行克隆和序列分析,以完善IGFs与其受体作用的调控理论,为IGFs系统用于鱼类养殖、促进鱼类生长与繁殖提供理论基础。
氨基酸序列分析表明石斑鱼胰岛素样生长因子I受体前蛋白原氨基酸全序列为1413aa,成熟肽为1384aa。使用Clustalx算法,将斜带石斑鱼IGF-IR前蛋白原氨基酸全序列与其它物种的IGF-R序列进行同源性比较,发现两个主要的功能区即富含亮氨酸区和酪氨酸激酶区的保守性非常高,羧基端的变异性比较大,本发明的石斑鱼IGF-IR序列属于b型。
本发明的石斑鱼胰岛素样生长因子I受体基因是以石斑鱼下丘脑总RNA反转录得到的cDNA为模板,经PCR和Gene RACER方法扩增而得到的。
本发明用于表达石斑鱼IGF-IR重组蛋白的IGF-IR成熟肽基因序列是以石斑鱼胰岛素样生长因子I受体基因双链DNA为模板,经PCR方法扩增而得到的,它来源于石斑鱼胰岛素样生长因子I受体基因的α亚基所对应的基因片段。
本发明还构建了上述表达石斑鱼IGF-IR重组蛋白的IGF-IR成熟肽基因序列的载体;特别是含有该基因的大肠杆菌克隆载体以及表达载体。这些载体的构建方法是按常规方法,将通过PCR方法合成的斜带石斑鱼胰岛素样生长因子I受体基因经酶切和分离纯化后,接入到已有的相应载体的相应酶切位点之间,即构建成所需的含有石斑鱼胰岛素样生长因子I受体基因的表达载体。
上述含石斑鱼胰岛素样生长因子I受体基因的大肠杆菌表达载体优选由本发明合成的石斑鱼胰岛素样生长因子I受体基因与大肠杆菌表达载体pET15b构建成的重组表达载体,命名为pET15b-IGF-IR。
本发明还用上述含有石斑鱼胰岛素样生长因子I受体基因的相应表达载体分别构建了能高效表达石斑鱼胰岛素样生长因子I受体基因的大肠杆菌重组株。
本发明的上述能表达石斑鱼胰岛素样生长因子I受体大肠杆菌重组菌株优选由含有石斑鱼胰岛素样生长因子I受体基因的表达载体pET15b-IGF-IR转化大肠杆菌BL21而得到的菌株,命名为pET15b-IGF-IR-BL21。
本发明还提供了利用上述大肠杆菌重组株生产石斑鱼胰岛素样生长因子I受体的方法。先将将菌种接种在含有氨苄青霉素的LB液体培养基中,37℃,200转/分培养过夜,次日接种于相同培养基中,并经IPTG诱导,37℃,200转/分培养,10小时后收集菌体,经分离纯化得到重组石斑鱼胰岛素样生长因子I受体产品。
本发明的有益效果石斑鱼具有重大的经济价值,采用常规的基因工程技术,利用本发明的石斑鱼胰岛素样生长因子I受体基因,可以生产重组石斑鱼IGF-I受体蛋白,用于制备鱼苗苗种促生长剂或添加剂,促进了鱼苗的快速生长,具有重大的经济效益。

4.如权利要求3所述的石斑鱼胰岛素样生长因子受体基因在制备石斑鱼鱼苗促生长剂或添加剂中的应用。
全文摘要
本发明公开了一种石斑鱼胰岛素样生长因子I受体基因,该基因是以石斑鱼下丘脑总RNA为模板,经RT-PCR和Gene RACER方法而得到的具有石斑鱼胰岛素样生长因子I受体基因cDNA序列的基因片段。利用本发明可以获得来源稳定、成本便宜的石斑鱼胰岛素样生长因子I受体的重组蛋白,在制备鱼苗促生长剂或添加剂中有着重要的应用。
