【摘要】：為了克隆麥洼牦牛IL-1β基因并分析其蛋白質(zhì)結(jié)構(gòu)及表達,給研究IL-1β基因的生物學功能提供理論基礎(chǔ),試驗利用RT-PCR方法擴增麥洼牦牛IL-1β基因序列,分析IL-1β基因在不同組織中的表達情況,通過生物學軟件進行核酸序列分析及蛋白質(zhì)結(jié)構(gòu)預測。結(jié)果表明:麥洼牦牛IL-1β基因大小為899 bp,Gen Bank登錄號為KU510225。此序列編碼266個氨基酸,蛋白質(zhì)分子質(zhì)量為30 684.0 u,不含跨膜區(qū)且沒有信號肽;蛋白二級結(jié)構(gòu)以α-螺旋為主,三級結(jié)構(gòu)與小鼠IL-1β蛋白結(jié)構(gòu)類似。IL-1β基因在各組織中表達量的順序為脾臟肝臟心臟肺臟腎臟。說明試驗成功克隆了麥洼牦牛IL-1β基因,在脾臟表達量高,表明IL-1β基因可能參與機體的免疫應(yīng)答。
[Abstract]:In order to clone and analyze the protein structure and expression of IL-1 尾 gene in Maiwa yak, and to provide a theoretical basis for studying the biological function of IL-1 尾 gene, RT-PCR was used to amplify the IL-1 尾 gene sequence of Mai WA yak. The expression of IL-1 尾 gene in different tissues was analyzed. Nucleic acid sequence analysis and protein structure prediction were carried out by biological software. The results showed that the size of IL-1 尾 gene of Maiwa yak was 899 bp,Gen Bank and the accession number was KU510225.. This sequence encodes 266 amino acids with a molecular weight of 30 684.0 u, no transmembrane region and no signal peptide. The secondary structure of the protein was 偽 -helix, and the tertiary structure was similar to that of mouse IL-1 尾 protein. The order of expression of IL-1 尾 gene in each tissue was spleen, liver, heart, lung and kidney. The results showed that the IL-1 尾 gene of Maiwa Yak was cloned successfully and expressed in the spleen, indicating that the IL-1 尾 gene might be involved in the immune response of the body.
