Prediction of B cell epitopes of tumor-associated protein EIF4G1 subtypes

Objective To predict the B cell epitopes of tumor-associated protein EIF4G1 subtypes.Methods The sequences of all the protein subtypes of EIF4G1 were retrieved from NCBI protein database.Based on single parameter evaluation,including hydrophilicity,flexility,antigenicity,the B cell epitopes of the EIF4G1 protein subtypes were predicted using NPS@structure software and ABCpred software.Results EIF4G1 protein had five subtypes.The variation of the five different EIF4G1 subtypes was limited within a 300aa region.We identified eight epitopes locating in or near 14-19,21-27,52-61,106-112,113-139,183-189,201-216, and 217-224, which can be used to identify specific B cell epitopes of different protein subtypes. Conclusion B cell epitopes of EIF4G1 protein subtypes do exist, and they may be used for the protein subtypes evaluation and early diagnosis of tumor patients using artificially-produced matched peptides.
