羊口疮病毒F1L蛋白二级结构分析与表位预测
Prediction of secondary structures and cell epitopes of F1L protein of ORFV
摘要
Abstract
The network platform SOPM A server was used to predict the secondary structure of ORFV F 1L protein . On the basis of the DNAStar prediction results (hydrophilicity , accessibility , flexibility and antigenicity ) , the B cell epitopes of ORFV F1L protein was predicted by screening the secondary structure and followed by verification using ABC prod program . The cytotoxic T cell (CTL) epitopes of ORFV F1L protein were predicted by combination of quantitative matrix (QM ) and artificial neural network (ANN) . T helper (Th) epitopes of ORFV F1L protein were predicted by an online server for the prediction of M HC class II-peptide binding affinity . The result showed that ORFV F1L protein had alpha helixes (34 .71% ) , random coils (40.59% ), β-sheet (18.82% ) and β-turn (5.88% ). No signal peptide was found, while 7 B-cell epitopes, 2 CTL epitopes and 3 Th epitopes of ORFV F1L protein were predicted . These findings would provide theoretical basis for establishment of ORFV diagnosis method , preparation of monoclonal antibody and development of vaccine .关键词
