摘要: 旨在获得中华大蟾蜍肌动蛋白序列全长。以中华大蟾蜍(Bufo bufo gargarizans)耳后腺为材料,提取总RNA,通过转录组高通量测序快速得到中华大蟾蜍肌动蛋白基因(BbgActin)cDNA全长2 055 bp,通过RT-PCR技术对其ORF序列进行验证,并对BbgActin基因进行分析。序列分析表明,BbgActin基因开放阅读框长1 131 bp,编码376个氨基酸。通过BLAST P程序分析,所得序列与GenBank数据库中肌动蛋白基因序列相似度均在89%以上,氨基酸序列的相似性达90%以上。系统进化分析表明,BbgActin与γ-Actin聚为一类,所得中华大蟾蜍肌动蛋白属于γ-Actin。首次获得了中华大蟾蜍γ-Actin cDNA全长序列。

Abstract: In order to obtain the full-length of actin’s sequence in Bufo bufo gargarizans,the total RNA was extracted from the parotid gland of B. bufo gargarizans,and high-throughput sequencing of transcriptome was used to obtain the full-length cDNA of actin (BbgActin)in B. gargarizansas 2 055 bp. The sequence of ORF(open reading frame)was verified by RT-PCR and sequencing. Sequence analysis showed that the ORF was 1 131 bp encoding for a polypeptide of 376 amino acid residues. Homologous alignment by software BLAST P revealed that it shared over 89% of nucleotide identities and over 90% of amino acid identities with actins from other animals in GenBank. Phylogenetic analysis showed that BbgActin clustered in a class with γ-Actin and highly conserved during evolution. In conclusion,it is the first time to acquire the full-length sequence of γ-Actin cDNA in B. bufo gargarizans,which lays a foundation for further studies on the role of gene Bbgγ-Actin on the life activities of B. bufo gargarizans.
