Ore-binding factor alpha 1 plays an essential role in bone formation and osteoblast differentiation and serves as a master gene regulating osteoblast-specific gene expression. The gene is expressed in cells of the osteoblast lineage only, and when expressed in non-skeletal cells, the cells assume many of the characteristics of an osteoblast.

In our experiment, the GADes gene from rat brain was cloned and expressed in E.coli, so as to make the recombinant GADes produced by gene technology for clinical application and further study on the relation between GAD and type 1 diabetes mellitus.Firstly, with the pUClS/GADes recombinant plasmid as template, the full-length encoding sequence of GADes was amplified by PCR, and cloned into pGEM-T vector. Secondly, the target gene was cut by EcoRI and inserted into restriction sites of pET42a vector for expression.

本研究首先用PCR方法，以pUC18/GAD_(65)为模板，扩增目的基因，克隆到pGEM-T载体中，构建pGEM-T/GAD_(65)重组质粒，然后用EcoRI酶切，切下的目的基因片段插入pET42a融合型表达载体中，经酶切鉴定和测序，证实插入方向、读码框架正确；重组表达质粒转化大肠杆菌BL21(DE_3)中诱导表达，表达产物经亲和层析纯化后获得了融合蛋白GST-GAD_(65)。

Segments of Adh gene in azuki bean (variety KS 5), covering an interval between partial intron 3 and intron 9, were amplified and sequenced with two pairs of primers. The result has proven the viability of using conserved sequences in a completely sequenced gene of one species to clone same gene in another species. In the comparison between Adh genes of azuki bean and pea, high sequence similarity (about 80%) in exon and long length difference (up to 116 bp) in intron were found. Besides, the edge regions of Adh introns with GT/AG counterparts and more conserved sequences than central regions was observed in both species.
