Galectin-3, a factor involved in the splicing of pre-mRNA, shuttles between the nucleus and the cytoplasm. Previous studies have shown that incubation of fibroblasts with leptomycin B resulted in the accumulation of galectin-3 in the nucleus, suggesting that the export of galectin-3 from the nucleus may be mediated by the CRM1 receptor. A candidate nuclear export signal fitting the consensus se...

Los1p, the Saccharomyces cerevisiae exportin-t homologue, binds tRNA and functions in pre-tRNA splicing and export of mature tRNA from the nucleus to the cytosol. Because LOS1 is unessential in yeast, other pathways for tRNA nuclear export must exist. We report that Cca1p, which adds nucleotides C, C, and A to the 3' end of tRNAs, is a multicopy suppressor of the defect in tRNA nuclear export c...

[1] In the past two decades, a number of studies have been carried out in the Southern Ocean to look at export production using drifting sediment traps and thorium-234 based measurements, which allows us to reexamine the validity of using the existing relationships between production, export efficiency, and temperature to derive satellite-based carbon export estimates in this region. Comparison...

This paper reports an exploratory study of 19 Australian SMEs which had successfully used eCommerce develop to or enhance their export capability. The purpose of the study was to identify both successful adoption processes and impediments to using eCommerce for export. Few companies had adopted a strategic and planned approach to managing this adoption. The lack of easily accessed and trustwort...

The bacterial flagellum assembles in a strict order, with structural subunits delivered to the growing flagellum by a type III export pathway. Early rod-and-hook subunits are exported before completion of the hook, at which point a subunit-specificity switch allows export of late filament subunits. This implies that in bacteria with multiple flagella at different stages of assembly, each export...

exports have direct effects on iran’s economic growth; therefore, a variety of state and private owned institutes promote iranian companies’ export activities via export promotion programs (epps). the main goal of these programs is to improve the export performance of iranian companies and to motivate export activities of those companies. to explore the effects of export promotion programs on e...

Eukaryotic cells export several different classes of RNA molecule from the nucleus, where they are transcribed, to the cytoplasm, where the majority participate in different aspects of protein synthesis. It is now clear that these different classes of RNA, including rRNAs, tRNAs, mRNAs and snRNAs, are specifically directed into distinct but in some cases partially overlapping nuclear export pat...

Combining international business (IB) research with the knowledge based view, this paper examines factors affecting the export propensity and export performance of high-technology SMEs in an emerging economy. Using a unique, hand-collected dataset of 711 SMEs from Zhongguancun Science Park in China, it argues that export orientation and performance depend not only on the development of capabili...

Nuclear mRNA export is a highly complex and regulated process in cells. Cellular transcripts must undergo successful maturation processes, including splicing, 5'-, and 3'-end processing, which are essential for assembly of an export competent ribonucleoprotein particle. Many viruses replicate in the nucleus of the host cell and require cellular mRNA export factors to efficiently export viral tr...
