人肌红蛋白基因外显子一的生物信息学分析

人肌红蛋白基因外显子一的生物信息学分析一 Introduction：Myoglobin, the article is composed of a peptide chains and a binding protein of heme prosthetic group, is within the muscle oxygen storage protein, its oxygen saturation of the elliptic curve.Myoglobin is the main protein of skeletal muscle and cardiac muscle, when muscle damage, leakage to the circulating in the blood in muscle tissue, increase the serum concentration of myoglobin, the index is used to determine whether muscle damage.二 Purpose：对人肌红蛋白基因外显子一基因序列使用 “Bioedit和DNAMAN、anthe5.0”及相关网站进行GC含量统计、电子酶切、引物设计、基因在人类基因组中的定位、电子克隆及蛋白在细胞内的定位、氨基酸组成统计、分子量、等电点、亲疏水性、信号肽分析（跨膜区域）、二级结构（含保守结构域）及三维结构分析，miR分析，启动子分析等。其中抗原表位分析、多序列比对和进化分析等。三 The nature and function of myoglobin：Nature: myoglobin = a polypeptide chain + a prosthetic group polypeptide chain, composed of 153 amino acid residuesProsthetic group: heme prosthetic groupMolecular weight: 16, 700Function: transport of oxygen and oxygen storage function in muscle tertiary structure of myoglobin四 Key word: 肌红蛋白（myoglobin）五 Implements and methods：采用Bioedit和DNAMAN分析软件工具和在线有关蛋白质和核酸方面的分析软件，分别进行核酸和蛋白质两个方面的分析。核酸分析首先从pubmed核酸数据库中搜索到人的Myoglobin核酸序列，分别进行序列的基本性质分析，限制性酶谱分析及其基因在染色体上的定位分析。具体操作方法将根据上述各个软件上“Help”文件进行，基因在染色体上的定位分析根据网页上的操作说明进行。从pubmed蛋白质数据库中搜索到人的Myoglobin和整个前体Myoglobin蛋白质序列，分别进行蛋白序列的基本性质分析（氨基酸组成、分子量、等电点），亲疏水性分析，蛋白酶切位点分析，信号肽序列分析，二级结构和三维结构分析，同源序列和进化分析。二级结构分析包括结构功能域、Motif、保守位点等，具体操作方法将根据上述各个软件上“Help”文件和网页上的操作说明进行。Resluts:1.从NCBI中可以得到一下有关Myoglobi蛋白分子的信息：Humanmyoglobingene, exon 1GenBank: M10090.1LOCUS HUMMGI1 2552 bp DNA linear PRI 07-JAN-1995DEFINITION Human myoglobin gene, exon 1.ACCESSION M10090VERSION M10090.1 GI:187580KEYWORDS Fok family repetitive sequence; direct repeat; myoglobin; repeat region; tandem repeat.SEGMENT 1 of 3SOURCE Homo sapiens (human) ORGANISM Homo sapiens Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.REFERENCE 1 (bases 1 to 2552) AUTHORS Akaboshi,E.
