Abstract

Automated annotation of G protein-coupled receptors (GPCRs) has been an intriguing topic because of the important role of GPCRs in pharmaceutical research. The diverse nature of GPCRs results in the lack of overall sequence homolog among members, making the classification of GPCRs a challenging task. In this paper, we propose a new method to classify GPCRs based on only their primary sequences. We extract feature vectors from protein sequences based on various physicochemical properties and use the Support Vector Machine (SVM) for the classification. When features derived from multiple properties are used together, we obtain the accuracy of 97.61% on GPCR Level I subfamily classification and 99.94% on GPCR superfamily recognition in double cross-validation tests. The results compare favorably with those reported in previous publications.
