Identification and analysis of putative promoter motifs in Flavivirus genome.
The genus Flavivirus comprises medically significant pathogenic virus; causing several infections in humans worldwide. Flavivirus genomes are 10-11 kb approximately and encode both structural and non structural region. The non structural region plays fundamental role in the stability, regulation and cell cycle of virus. The complete genomes of 26 Flavivirus were used for identification of promoter motifs through in silico approaches. The promoter sequences were encoded in merely 16 viruses and 10 viruses could not encode it. All these in silico identified promoter motifs was confirmed and verified with the known experimental data. This analysis suggests that presence of promoter may play a crucial role in the pattern of gene expression, regulation networks, cell specificity and development. It may also be useful for designing efficient expression vector and target specific delivery system in the gene therapy.
