摘要
牦牛(Bos grunniens)是生存于青藏高原的特有物种,对低氧、强紫外线的高原环境具有很强的适应性,可能形成了保护中枢神经系统免受低氧损伤与氧化损伤的特殊机制。金属硫蛋白(MTs)是一类低分子量、高半胱氨酸含量和富含金属的细胞质蛋白,具有重金属解毒,清除自由基,保护脑细胞免受缺血缺氧性脑损伤,以及促进多种脑病理损伤修复等作用。推测金属硫蛋白可能对牦牛适应低氧、强紫外线的高原环境发挥了重要作用,具有相应的分子遗传基础,然而牦牛MT-Ⅲ和MT-Ⅳ基因的研究尚未见报道。本论文采用RT-PCR、5'RACE等基因克隆技术首次克隆了牦牛MT-Ⅲ转录区序列和MT-Ⅳ基因序列,采用生物信息学方法对牦牛MT-Ⅲ和MT-Ⅳ蛋白质性质和结构进行了预测,并构建了MT-Ⅲ原核表达体系,主要获得以下结论:
     1、牦牛MT-Ⅲ基因转录区序列全长1484bp(GenBank Accession No.:DQ492300和EU653285),5'非翻译区、外显子1、内含子1、外显子2、内含子2、外显子3和3'侧翼区长度依次为56bp、31bp、232bp、66bp、817bp、110bp和172bp。
     2、牦牛MT-Ⅲ基因编码区长207bp,编码68个氨基酸,其中Cys占27.9%,不含芳香簇氨基酸。与MT-Ⅰ和MT-Ⅱ相比,在N端第四个氨基酸后插入一个苏氨酸,在C端插入了GEGAEA序列。牦牛MT-Ⅲ蛋白质分子量6.94KDa,没有明显的疏水区,没有跨膜结构域,不存在信号肽,是一种细胞内蛋白质。
     3、与人和鼠相比,牦牛MT-Ⅲ基因编码区第88位的碱基T突变成A,使氨基酸序列中第30位保守的Cys被Ser代替,这可能对牦牛MT-Ⅲ的结构和功能产生一定的影响,有待深入研究。
     4、牦牛MT-Ⅳ基因三个外显子和内含子全长2099bp(GenBank Accession No.:EU665491),三个外显子长度分别为31bp、66bp和92bp,二个内含子长度分别为1392bp和518bp。编码区长189bp,编码62个氨基酸,其中Cys 20个,不含芳香簇氨基酸。与MT-Ⅰ和MT-Ⅱ相比,在N端第四个氨基酸后插入了一个谷氨酸。MT-Ⅳ蛋白质分子量6.25KDa,没有明显的疏水区,没有跨膜结构域,不存在信号肽,是一种细胞内蛋白质。
     5、研究表明MT-ⅣmRNA在不存在复层扁平鳞状上皮细胞的器官肝脏、脾脏、脑和脑垂体中也有表达,表明MT-Ⅳ可能不仅限于在复层扁平鳞状上皮细胞中表达,这有待于深入研究。
     6、牦牛MT-Ⅲ和MT-Ⅳ编码区序列和氨基酸序列与其它哺乳动物的高度同源,在进化上高度保守,建立的系统进化树与比较形态学和生理学分类结果一致。但非编码区序列同源性很低,这些序列可能存在物种特异性。
     7、以鼠MT-Ⅲ三级结构为模板,预测出了牦牛MT-Ⅲα结构域的三级结构,表明牦牛MT-Ⅲ蛋白质在第43-46氨基酸间形成α螺旋;以兔MT-Ⅱ三级结构为模板,预测出了牦牛MT-Ⅳ三级结构,MT-Ⅳ没有规则的二级结构,与其它MTs来型不同,MT-Ⅳ两个结构域连接序列为RKS。
     8、采用pET-42a(+)表达载体,BamH I、XHoI酶切,构建了pET-42a(+)-MT-Ⅲ融合表达重组质粒,转化E.Coli BL21(DE3)plysS表达菌,建立了IPTG诱导表达MT-Ⅲ原核表达体系。
The yak species(Bos grunniens) represents a unique bovine species adapted to the Tibetan plateau of China at altitudes of 3,000m above sea level with intense ultraviolet radiation.Consequently,yak adapted to this environment likely have special physiological adaptive mechanisms to protect their central nervous systems against hypoxic and oxidative injury.The metallothionein(MT) family is a class of low molecular, intracellular,and cysteines-rich proteins with a high affinity for metals.Accumulating studies have demonstrated MTs fulfill unique biological roles in scavenger of free radicals,metal detoxication and homeostasis,and homeostasis of the central nervous system and in the etiology of neuropathological disorders. The MTs of yak maybe important for protecting yak from hypoxic and oxidative injury and it is essential to study MTs gene of yak.However,there were no detailed reports concerning MT-Ⅲand MT-Ⅳgene in Yak. In this study,MT-Ⅲand MT-Ⅳgene were cloned by reverse transcriptase-polymerase chain reaction (RT-PCR) and 5'-RACE methods firstly.To analysis the gene structure and the protein characteristics of MT-Ⅲand MT-Ⅳby bioinformatics methods,and established the expression system of MT-Ⅲproteins in E. coli..The main results were got as following:
     1.The translated region sequence of MT-Ⅲgene in yak was gotten,the total length was 1484bp,the length of 5' UTR,exonl,intronl,exon2,intron2,exon3 and 3'UTR was 56bp,31bp,66bp,817bp,110bp and 172bp respectively.The sequences had been deposited in the GenBank data base(Accession No.DQ492300 and EU653285 ).
     2.The coding regions of Yak MT-Ⅲwere composed by 207 nucleotides,encoded a 68-amino acid protein, and contained 19 cysteine residues,no aromatic AA.Compared to 61 amino acids for MT-Ⅰand MT-Ⅱisoforms,MT-Ⅲcontained 2 inserts,a single threonine in the N terminal region and a glutamic acid rich hexapeptide(GEGAEA) in the C-terminal region.The molecular weight of Yak MT-Ⅲis 6.94 KDa,analysis of hydrophobicity,transmembrane region,and signal peptides suggested that MT-Ⅲof the yak are nonsecretory proteins.
     3.The corresponding conservative Cys~(30) of MT-Ⅲin human and mouse was replaced by Ser~(30),due to a mutation at the 88th nucleotide acid where T mutated into A,it may implied some structural/or dynamic and physiological function differences.
     4.The sequence length of MT-Ⅳgene in yak is 2099bp,including 3 exons and 2 introns,the length of 3 exons were respectively 31bp,66bp and 92bp,the length of 2 introns were respectively 1392bp and 518bp,the sequences had been deposited in the GenBank data base(Accession No.EU665491).The coding regions were composed by 189 nucleotides,encode a 62-amino acid protein,and contain 20 cysteine residues,no aromatic AA.Compared to MT-Ⅰand MT-Ⅱisoforms,MT-Ⅳcontained a single glutamic inserts in the N terminal region.The molecular weight of Yak MT-Ⅲwas 6.25 KDa.,Analysis of hydrophobicity,transmembrane region,and signal peptides suggested that MT-Ⅳof the yak are nonsecretory proteins.
     5.The coding region of MT-Ⅳwas cloned by RT-PCR from liver,spleen,brain and pituitary in yak,yellow cattle,sheep and goat,in which there are no cornified stratified squamous epithelium,it applied the expression of MT-Ⅳnot only limited in stratified squamous epithelium.
     6.The coding regions and amino acid sequence of MTs among mammalian are highly identical,and highly conserved in evolution.But the identity of the noncoding regions sequence are very low,these sequence is special for species likely.
     7.Modelling on three-dimensional solution structure of mouse MT-Ⅲ,the three-dimensional solution structure ofα-domain of MT-Ⅲin yak was predict,and lainα-helix from the Glu~(43rd) to Ala~(46th).Modelling on three-dimensional solution structure of rabbit MT-Ⅱ,the three-dimensional solution structure of MT-Ⅳin yak was predict,different from other MT isforms,the conserved hinge region between two domain in other MT isoforms were replaced by RKS in MT-Ⅳ.
     8.Establishing pET-42a(+)-MT-Ⅲexpression system in E.Coli BL21(DE3)plysS with IPTG.
