Abstract: Identification of essential proteins helps to understand the basic needs of cell survival and find new methods for disease treatment. Protein itself carries complex biological characteristics, and it is impossible to accurately judge their criticality only by network topology. In this paper, a new method is proposed to improve the accuracy of identifying essential proteins. Firstly, considering the network topology and the importance of proteins in different sub-cells, an indicator called SNC is proposed. Secondly, SIDC indicatoris defined by using the characteristics of proteins in subcellular and complex information. Finally, based on the network topology and multi-source biological information, a new protein recognition algorithm CTB is proposed. Experiments on YDIP, YMIPS, Krogan data sets using accuracy recall and other evaluation methods show that the method in this paper improves theperformance of identifying key proteins.
