Characterization of cis- and trans-acting elements in the imprinted human SNURF-SNRPN locus
The imprinted SNRPN locus is a complex transcriptional unit that encodes the SNURF and SmN polypeptides as well as multiple non-coding RNAs. SNRPN is located within the Prader-Willi and Angelman syndrome (PWS/AS) region that contains multiple imprinted genes, which are coordinately regulated by a bipartite imprinting center (IC). The SNRPN 5' region co-localizes with the PWS-IC and contains two...
متن کاملVasopressin mRNA localization in nerve cells: characterization of cis-acting elements and trans-acting factors.
mRNA localization is a complex pathway. Besides mRNA sorting per se, this process includes aspects of regulated translation. It requires protein factors that interact with defined sequences (or sequence motifs) of the transcript, and the protein/RNA complexes are finally guided along the cytoskeleton to their ultimate destinations. The mRNA encoding the vasopressin (VP) precursor protein is loc...

متن کاملcis- and trans-acting elements in flavivirus RNA replication.
Most of the seven flavivirus nonstructural proteins (NS1 to NS5) encoded in the distal two-thirds of the RNA positive-sense genome are believed to be essential components of RNA replication complexes. To explore the functional relationships of these components in RNA replication, we used trans-complementation analysis of full-length infectious RNAs of Kunjin (KUN) virus with a range of lethal i...
متن کاملRegulation of the large (*1000 kb) imprinted murine Ube3a antisense transcript by alternative exons upstream of Snurf/Snrpn
Most cases of Angelman syndrome (AS) result from loss or inactivation of ubiquitin protein ligase 3A (UBE3A), a gene displaying maternal-specific expression in brain. Epigenetic silencing of the paternal UBE3A allele in brain appears to be mediated by a non-coding UBE3A antisense (UBE3A-ATS). In human, UBE3A-ATS extends 450 kb to UBE3A from the small nuclear ribonucleoprotein N (SNURF/ SNRPN ) ...
