Cis-acting influences on Alu RNA levels.
The human short interspersed repeated element (SINE), Alu, amplifies through a poorly understood RNA-mediated mechanism, termed retroposition. There are over one million copies of Alu per haploid human genome. The copies show some internal variations in sequence and are very heterogeneous in chromosomal environment. However, very few Alu elements actively amplify. The amplification rate has dec...

متن کاملThe cis-acting signals that target proteins to exosomes and microvesicles.
Proteins bud from cells in small single-membraned vesicles (~50-250 nm) that have the same topology as the cell. Known variously as exosomes and microvesicles (EMVs), these extracellular organelles are enriched for specific proteins, lipids, carbohydrates and nucleic acids. EMV biogenesis plays critical roles in protein quality control and cell polarity, and, once released, EMVs can transmit si...
متن کاملAnalysis of the proteins and cis-acting elements regulating the stress-induced phage shock protein operon.
The phage shock protein operon (pspABCE) of Escherichia coli is strongly induced by adverse environmental conditions. Expression is controlled principally at the transcriptional level, and transcription is directed by the sigma factor sigma 54. PspB and PspC are required for high-level psp expression during osmotic shock, ethanol treatment and f1 infection, but heat-induced expression is indepe...
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...
