[Method] The amino acid sequence of rice allergen RAG1 was acquired from Expasy protein database. The secondary structure of RAG1 was predicted by DNAStar Protean software with Gamier-Robson program, Chou-Fasman program and Karplus-Schulz program; the B cell epitopes of RAG1 was predicted with the Kyte Doolittle hydrophilic program, Emini surface accessibility program and Jameson-Wolf antigenic index program. [Result] The predictions on secondary structure and B cell epitopes showed that the regions of 33-44, 119-129, 155-163 were the dominant B cell epitopes. [Conclusion] This study predicted the potential dominant B cell epitopes in rice allergen RAG1 by comprehensive use of multi-methods and multi-parameters, and provided a theoretical basis for further researches on identification, antigen modification and epitope vaccine design of RAG1 B cell epitopes.展开更多

We previously reported that mice with a homozygous deficiency for NF-κBp50 spon- taneously developed optic neuropathy. We examined the expression and activation of pro-apoptotic factor（s） that mediate optic neuropathy in p50-/- mice. Recombination activating gene 1 （Ragl） is known to regulate the recombination of immunoglobulin V（D）J.展开更多
