Overlap PCR克隆黄牛脂肪特异性磷脂酶A2基因(AdPLA)及其原核表达
Cloning of Cattle Adipose-specific phospholipase A2 Gene (AdPLA) by Overlap PCR and Its Prokaryotic Expression
摘要
Abstract
Adipose-specific phospholipase A2 gene (A dPLA ) is a major regulator of adipocyte lipolysis, and in order to construct the prokaryotic expression system of cattle AdPLA gene, the coding sequence of A dPLA gene was obtained by Overlap PCR method from cattle {Bos taurus) genomic DNA and cloned into pGM-T vector, the positive clone sequencing result was same as the sequence in GenBank (GenBank No. NMOO1075280). The positive plasmid was digested with BamH. I and HindW, then the fragment was ligated with the expression vector pET28a (+), the recombined plasmid was transformed into Escherichia coli BL21 (DE3) and induced with IPTG. SDS-PAGE result showed that the fusion protein Ris-AdPLA was expressed in E.coli, which indicated the prokaryotic expression system of recombined vector pET28a (+)-AdPLA was constructed successfully. This study provides a good foundation for further research of cattle AdPLA gene and lays a pathway for developing the AdPLA protein product in the future.关键词
