A novel GLP cDNA clone was isolated from a cDNA library of Tamarix hispida. ThGLP, coded 225aa, possesses conserved motif of plant germin and Germin-like protein. ThGLP belongs to true germin subfamily through phylogenetic analyses. Gene expression profiles in roots and leaves were evaluated using real-time quantitative RT-PCR. The results show that the gene was highly induced by drought, salt, low temperature, CdCl2 and abscisic acid treatments. Our results demonstrate that the ThGLP gene is expressed in leaves and roots, is involved in different abiotic stress re-sponses and controlled by an ABA-dependent signaling pathway.展开更多
胰高血糖素样肽-1(glucagon-like peptide-1,GLP-1)是一种肠促胰岛素激素,具有很好的综合降糖效果,但其在血浆中的半衰期只有短暂几分钟,限制了GLP-1在临床方面的应用.为延长GLP-1的半衰期,合成了GLP-1-Fc融合基因,将N-糖基化作用的受...胰高血糖素样肽-1(glucagon-like peptide-1,GLP-1)是一种肠促胰岛素激素,具有很好的综合降糖效果,但其在血浆中的半衰期只有短暂几分钟,限制了GLP-1在临床方面的应用.为延长GLP-1的半衰期,合成了GLP-1-Fc融合基因,将N-糖基化作用的受体天冬酰胺突变为丙氨酸,构建了无糖基化修饰的GLP-1-Fc(N126A)融合表达载体,利用酵母表达系统成功表达了GLP-1-Fc(N126A)融合蛋白,并利用r Protein A获得了高纯度融合蛋白.展开更多
