Na-K-Exchanging ATPase is a universal cell membrane protein in higher eukaryotic cells which mediates the anti-concentration gradient exchange of intracellular Na+ for extracellular K+. It plays essential metabolic roles such as maintaining sodium and potassium ion gradients across the plasma membrane. The targeted sequences were amplified by PCR to determine the genome structure of the hithertofore unsequenced portion of the alpha 1 subunit of the human Na-KExchanging ATPase gene which encodes 80-130 aa of its extracellular domain using two different templates, human genomic DNA and a human muscle cDNA library. The PCR products were analyzed by restriction endonuclease digestion and then cloned into a plasmid vector for chemiluminescence sequencing and further analysis.

Na-K-Exchanging ATPase是一种普遍存在于高等生物体内的细胞膜蛋白，主要参与介导K+和Na+在细胞内外之间的逆浓度梯度的转运，并维持一定细胞内外的离子梯度，我们采用聚合酶链式反应方法分别以人基因组DNA及cDNA文库为模板对人Na-K-Exchanging ATPaseα1亚单位基因胞外区约80-130位氨基酸编码序列进行扩增，限制性酶切分析扩增产物，并进行荧光测序，对测序结果进行同源性分析及剪接位点的搜索并对得到的核苷酸序列进行进一步的分析，发现人基因组DNA和cDNA经过扩增后分别得到833bp和195bp两种不同大小的片段Fg，Fc。

Attenuation The trp operon is also controlled by attenuation A leader sequence in the polycistronic mRNA upsteam of the coding region of the trpE structural gene encodes a 14 amino acid leader peptide including two tryptophan residues The RNA leader sequence can for several possible stem-loop secondary structures,one of which can act as a transcription terminator whilst a different stem-loop can act as an anti-terminator.

弱化作用 trp 操纵子也受到弱化作用的调控。在trpE结构基因编码区上游的多顺反子mRAN上有一段前导序列，可以编码一个含有14个氨基酸的前导肽，此肽中含有两个色氨酸残基。

A highly conserved sequence of 210 bp of AtNHX1 gene that encodes a Na+/H+ antiport protein was isolated from A.thaliana,the 210 bp fragment was amplified as RNAi target site and used in construction of RNAi vector,and was inserted into pHANNIBAL as reverted repeat with an intron.The expressional box was linked into the vector of pART27,NPTⅡgene is the screening marker in this vector.

利用RNAi研究植物基因功能，可选择靶基因的一段单一序列使基因家族中的单个成员沉默；也可以选择某一基因家族的多个成员具有的一段同源性很高的保守序列，设计针对这一序列的dsRNA表达载体使多个基因同时沉默，RNAi成为功能基因组学研究的重要手段。
