Knowing the subcellular localization of proteins within the cell is an important step in elucidating its role in biological processes, its function and its potential as a drug target for disease diagnosis. As the number of complete genomes rapidly increases, accurate and efficient methods that automatically predict the subcellular localizations become more urgent. In the current paper, we developed a novel method that coupled the discrete wavelet transform with support vector machine based on the amino acid polarity to predict the subcellular localizations of prokaryotic and eukaryotic proteins. The results obtained by the jackknife test were quite promising, and indicated that the proposed method remarkably improved the prediction accuracy of subcellular locations, and could be as an effective and promising high-throughput method in the subcellular localization research.
了解蛋白质在细胞内的亚细胞定位是阐明其在生物过程中的作用、功能以及作为疾病诊断的药物靶点的重要步骤。随着完整基因组数量的快速增加,自动预测亚细胞定位的准确高效方法变得更加迫切。在本论文中,我们开发了一种新的方法,该方法将离散小波变换与基于氨基酸极性的支持向量机相结合,用于预测原核和真核蛋白质的亚细胞定位。Jackknife 检验的结果非常有前景,表明所提出的方法显著提高了亚细胞位置的预测准确性,并且可以作为亚细胞定位研究中的一种有效且有前途的高通量方法。
