Protein-Protein Interactions (PPIs) play essential roles in most cellular
processes. Knowledge of PPIs is becoming increasingly more important, which has
prompted the development of technologies that are capable of discovering
large-scale PPIs. Although many high-throughput biological technologies have been
proposed to detect PPIs, there are unavoidable shortcomings, including cost, time
intensity, and inherently high false positive and false negative rates. For the
sake of these reasons, in silico methods are attracting much attention due to
their good performances in predicting PPIs. In this paper, we propose a novel
computational method known as RVM-AB that combines the Relevance Vector Machine
(RVM) model and Average Blocks (AB) to predict PPIs from protein sequences. The
main improvements are the results of representing protein sequences using the AB
feature representation on a Position Specific Scoring Matrix (PSSM), reducing the
influence of noise using a Principal Component Analysis (PCA), and using a
Relevance Vector Machine (RVM) based classifier. We performed five-fold
cross-validation experiments on yeast and Helicobacter pylori datasets, and
achieved very high accuracies of 92.98% and 95.58% respectively, which is
significantly better than previous works. In addition, we also obtained good
prediction accuracies of 88.31%, 89.46%, 91.08%, 91.55%, and 94.81% on other five
independent datasets C. elegans, M. musculus, H. sapiens, H. pylori, and E. coli
for cross-species prediction. To further evaluate the proposed method, we compare
it with the state-of-the-art support vector machine (SVM) classifier on the yeast
dataset. The experimental results demonstrate that our RVM-AB method is obviously
better than the SVM-based method. The promising experimental results show the
efficiency and simplicity of the proposed method, which can be an automatic
decision support tool. To facilitate extensive studies for future proteomics
research, we developed a freely available web server called RVMAB-PPI in
Hypertext Preprocessor (PHP) for predicting PPIs. The web server including source
code and the datasets are available at http://219.219.62.123:8888/ppi_ab/.
