Support vector machine for predicting protein interactions using domain scores

摘要

Protein-protein interactions play a crucial role in the cellular process such as metabolic pathways and immunological recognition.This paper presents a new domain score-based support vector machine(SVM) to infer protein interactions,which can be used not only to explore all possible domain interactions by the kernel method,but also to reflect the evolutionary conservation of domains in proteins by using the domain scores of proteins.The experimental result on the Saccharomyces cerevisiae dataset demonstrates that this approach can predict protein-protein interactions with higher performances compared to the existing approaches.
