Genetic and biochemical studies of poliovirus cis-acting replication element cre in relation to VPg uridylylation.
In addition to highly conserved stem-loop structures located in the 5'- and 3'-nontranslated regions, genome replication of picornaviruses requires cis-acting RNA elements located in the coding region (termed cre) (K. L. McKnight and S. M. Lemon, J. Virol. 70:1941-1952, 1996; P. E. Lobert, N. Escriou, J. Ruelle, and T. Michiels, Proc. Natl. Acad. Sci. USA 96:11560-11565, 1999; I. Goodfellow, Y....
متن کاملHigh-resolution structure of a picornaviral internal cis-acting RNA replication element (cre).
Picornaviruses constitute a medically important family of RNA viruses in which genome replication critically depends on a small RNA element, the cis-acting replication element (cre), that templates 3D(pol) polymerase-catalyzed uridylylation of the protein primer for RNA synthesis, VPg. We report the solution structure of the 33-nt cre of human rhinovirus 14 under solution conditions optimal for...
متن کاملThe foot-and-mouth disease virus cis-acting replication element (cre) can be complemented in trans within infected cells.
A temperature-sensitive (ts) mutation was identified within the 5'-untranslated region of foot-and-mouth disease virus (FMDV) RNA. The mutation destabilizes a stem-loop structure recently identified as a cis-acting replication element (cre). Genetic analyses indicated that the ts defect in virus replication could be complemented. Thus, the FMDV cre can function in trans. It is suggested that th...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولCRM1-dependent function of a cis-acting RNA export element.
Viruses often contain cis-acting RNA elements, which facilitate the posttranscriptional processing and export of their messages. These elements fall into two classes distinguished by the presence of either viral or cellular RNA binding proteins. To date, studies have indicated that the viral proteins utilize the CRM1-dependent export pathway, while the cellular factors generally function in a C...
