| sequence analysis and genomic organization of a new insect picorna-like virus, ectropis obliqua picorna-like virus, isolated from ectropis obliqua. | the complete nucleotide sequence of a new insect picorna-like virus, ectropis obliqua picorna-like virus (eopv), which causes a fatal infection of ectropis obliqua larvae, has been determined. the genomic rna of eopv is 9394 nt in length and contains a single, large open reading frame (nt 391-9351) encoding a polyprotein of 2987 aa. sequence comparisons with other viral polyproteins revealed that the consensus sequences for picornavirus rna helicase, protease and rna-dependent rna polymerase pro ... | 2004 | 15105531 |
| in vitro and in vivo identification of structural and sequence elements in the 5' untranslated region of ectropis obliqua picorna-like virus required for internal initiation. | ectropis obliqua picorna-like virus (eopv) is a newly described insect virus that is classified as a putative member of the genus iflavirus. the virus possesses a large, positive-sense rna genome encoding a single polyprotein that shares physicochemical properties with those of members of the family picornaviridae. the 5' untranslated region (5' utr) plays an important role in picornavirus translation initiation, as it contains an internal ribosome entry site (ires) that mediates cap-independent ... | 2006 | 17098984 |
| ectropis obliqua picorna-like virus ires-driven internal initiation of translation in cell systems derived from different origins. | ectropis obliqua picorna-like virus (eopv) is an insect rna virus that causes a lethal granulosis infection of larvae of the tea looper (ectropis obliqua). an internal ribosome entry site (ires) mediates translation initiation of eopv rna. here, bicistronic constructs were used to examine the 5' untranslated region (utr) of eopv for ires activity. the capacities of the eopv 5' utr ires and another insect virus ires, the cricket paralysis virus intergenic region ires, to mediate internal translat ... | 2007 | 17872537 |
