美洲大蠊新基因Parcxpwxxq01的分析及功能预测

为进一步研究已发现的美洲大蠊新基因Parcxpwxxq01，我们采用BLASTp，ORF Finder，ProtScale，ScanProsite和Tmpred Server等软件或数据库进行相似性比较、开放读码框预测和编码蛋白质的功能等生物信息学方法对该序列进行特征分析和功能预测，以获得该基因及其编码的蛋白质的更多功能提示。结果发现得到的Parcxpwxxq01序列是该基因的全长序列，该基因编码的蛋白质是一碱性跨膜蛋白，该蛋白质可能为美洲大蠊的药用有效成分，有进一步研究的价值。

Bioinformatic analysis and functional prognose of periplaneta Americana novel gene (Parcxpwxxq01)

To study the novel Periplaneta americana cDNA Parcxpwxxq01, various bioinformatic methods such as BLASTp, ORF Finder, ProtScale, ScanProsite and Tmpred Server were used to analyze and predict the feature and possible functions of the novel cDNA sequence. We get the results： Parcxpwxxq01 was the full- length of a novel Periplaneta americana gene. Von Heijine transmembrane analysis clewed that the protein of gene Parcxpwxxq01 encoding was a alkahnity transmembrane protein. The protein is perhaps the effective medicinal component. Therefore, the functions of the novel gene are valuable for further investigations.
