The VP2 protein, encoded by L2, contains neutralizing epitopes. Previously, a panel of neutralizing monoclonal antibodies (MAbs) to the BTV serotype 17 (BTV-17) prototype strain was generated and it was determined that the neutralization domain consists of three overlapping epitopes. Over 30 amino acid changes were found between a neutralized BTV-17 prototype strain and a non-neutralized BTV-17 198 strain. In this study, the L2 genes from eight additional strains, representing both the neutralized and non-neutralized groups of BTV-17, were sequenced to determine the degree of conservation of the previously characterized differences. Comparison of the deduced amino acid sequences showed that 91% (30/33) of the previously noted changes were conserved within each group. The sequence of the M5 gene that encodes VP5 was also examined, since this surface protein has also been shown to affect neutralization. No consistent changes were noted between the neutralized and non-neutralized groups of BTV-17 by analysis of the VP5 protein. Finally, the L2 sequences of five MAb neutralization escape mutants were determined to identify specific amino acids involved in neutralization and perhaps virulence. All five mutants contained 1-3 amino acid changes that were in close proximity to a previously described variable region. These amino acid changes likely define critical sites in the overlapping neutralization domains previously described. This is the first description of two BT virus populations that have distinct neutralization characteristics co-circulating in a defined geographical region.</p>","PeriodicalId":11197,"journal":{"name":"DNA sequence : the journal of DNA sequencing and mapping","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10425170701550524","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40959612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The title change also heralds the introduction of a new Editor-in-Chief for the Journal: Professor Rob de Salle of the American Museum of Natural History in New York. Professor de Salle has worked in conjunction with the former Editor, the Publisher and a new Editorial Board to provide a new direction for the Journal. Mitochondrial DNA will accept original high quality reports based on mapping, sequencing and analysis of mitochondrial DNA and RNA. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, medical genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The Editorial Board will also consider manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences, as well as papers that discuss the utility of mitochondrial DNA information in medical studies and in human evolutionary biology. The Journal is supported by a specially selected Editorial Board consisting of representatives from the fields of Human and Medical Mitochondrial DNA, MitoGenomics, Population Genetics and Mitochondrial Parasitology. To coincide with the launch of the new title we have also introduced a fully electronic, online submission system.

The GPI anchor is covalently linked to GAP by amide bond formation between the carboxyl terminus and phosphoethanolamine attached at the third mannose and mediated by a transamidase complex. Mediation of GPI synthesis is by the sequential additions of GPI-N-acetylglucosaminyltransferase (GPI-GnT) complex, the GlcN-PI de-N-acetylase, the GlcN-PI mannosyltransferases and the GPI lipid anchor phosphoethanolamine transferase complexes. We report a rice gene OsPIG-F that encodes a homolog to the human PIG-F protein, one of GPI lipid anchor phosphoethanolamine transferase complexes. The amino acid sequences of rice PIG-F consisted of six helix transmembrane domains, one glycosaminoglycan attachment site, one cGMP-dependent protein kinase phosphorylation site and a protein C phosphorylation site at the C-terminus. This unique structure of rice PIG-F indicates the typical membrane bound structure of a protein. Polyclonal antibody for rice PIG-F was found to be cross-reactive with a protein extracted from the leaves of rice. The levels of rice PIG-F transcripts were found to be abundant in leaves, moderately in the milky stage of seed development and less in the floral spikelet, indicating that the rice PIG-F gene was differentially regulated in specific tissues. Furthermore, the levels of rice PIG-F transcription were up-regulated by growth hormones including GA(3), NAA and kinetin.
