興義鴨MEF2A基因克隆及生物信息學(xué)分析
[Abstract]:In order to obtain the complete coding region (CDS) sequence of duck MEF2A gene, the genetic mechanism was further revealed. In this experiment, Xingyi duck was used to clone and obtain the CDS sequence of MEF2A gene by RT-PCR method. After sequencing and splicing of recombinant plasmid, the complete coding region sequence of MEF2A gene of Xingyi duck was preliminarily obtained, and 1 479 bp fragment was obtained. It contains start codon and stop codon and encodes 492 amino acids, and the molecular weight of the expressed protein is 53.14 KD. By sequence comparison, single nucleotide mutations were observed in G429A429AT66A66A ~ (1423) G ~ (1426) G and G ~ (1467) A, respectively. T661A and A1423 G mutations resulted in the changes of Cys (cysteine) to Ser (serine), Glu (glutamic acid) to Lys (lysine), respectively. The other sites were synonymous mutations. The physical and chemical properties and structural characteristics of Xingyi duck MEF2A protein were analyzed in order to lay a theoretical foundation for the further study of the characteristics of MEF2A protein and its mechanism of action.
