Abstract:
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.
