摘要: 参照GenBank公布的禽流感病毒基质蛋白M1基因序列,设计合成了1对特异性引物,采用RT-PCR法成功扩增并克隆了禽流感病毒M1基因。序列测定结果为M1基因cDNA全长759 bp,编码252个氨基酸。将其序列与数株甲型流感病毒M1基因序列进行比较,M1基因核苷酸同源性为99.1%~99.6%,推导氨基酸同源性为98.8%~99.6%,生物信息学分析表明,M1基因编码的蛋白质具有亲水性,有很强的抗原性,M1蛋白共有6个潜在的N-糖基化位点,可能存在3个蛋白激酶C磷酸化位点,存在2个酪蛋白激酶Ⅱ磷酸化位点。

Abstract: A pair of primer was designed according to the sequences of avian influenza virus (AIV) on GenBank website. Total RNA from AIV was taken as template to make RT-PCR amplification. The M1 gene of AIV was amplified by RT-PCR.M1 gene was 759 bp in length, encoding 252 amino acids. Comparing with other published M1 cDNA sequences. It showed that the homology of M1 gene was from 99.1% to 99.6%, and the homology of amino acids was from 98.8% to 99.60%.Bioinformatics analysis of this sequence showed that the protein of M1 was hydrophilicand highly antigenic. M1 includes six potential N-glycosylation sites, three potential proteinkinase C phosphorylation sites, two potential caseinkinaseⅡ phosphorylation sites.
