Prediction of Protein Subcellular Localization by Incorporating Sequence and Protein-Protein Interaction Features
-
摘要: 提出了一种基于序列和PPI特征的距离公式,可综合序列氨基酸组成和PPI对象、强弱等信息对两个蛋白质的相似性进行表征,并在此基础上提出了一种用于蛋白质亚细胞定位预测的K近邻算法。利用留一法对性能进行了评估,结果显示,在序列基础上加入PPI特征,可明显有助于亚细胞定位的预测;同时基于上述距离的K近邻算法也优于使用相同特征的SVM算法,表明该算法可以对蛋白质的亚细胞定位信息进行准确有效的预测。
