The yeast Sac3:Cdc31:Sus1:Thp1 (TREX-2) complex facilitates the repositioning and association of actively transcribing genes with nuclear pores (NPCs)-"gene gating"-that is central to integrating transcription, processing, and mRNA nuclear export. We present here the crystal structure of Sus1 and Cdc31 bound to a central region of Sac3 (the CID domain) that is crucial for its function. Sac3(CID...
On June 11, 2021, the EU issued revised Regulation on Control of Dual-Use Items Export (EU 2021/821, hereinafter referred to as "the Regulation") in its official gazette. The came into force September 9, and replaced EU's existing export control laws regulations, which were introduced 2009. Compared with proposal by European Commission for first time 2016, newly has made certain adjustments sco...
Export of mRNA from the nucleus is a central process in eukaryotic gene expression that has been implicated in several human diseases. Much of our understanding of how an mRNA is transported to the cytoplasm is derived from studies using yeast and fly models. We present here different mechanisms by which aberrant nuclear retention of mRNA can cause human disease. Emerging evidence that implicat...
In eukaryotic cells, the nuclear membrane creates a barrier between the nucleus and the cytoplasm. Whereas RNA synthesis occurs in the nucleus, they mostly function in the cytoplasm; thus export of RNA molecules from the nucleus to the cytoplasm is indispensable for normal function of the cells. The molecular mechanisms involved in each kind of cellular RNA export is gradually understood. The f...
a diversification of the country’s export structure through the concerted development of its export-oriented manufacturing capacity could offer a viable alternative, as also stipulated in the country’s second socioeconomic and cultural development plan, by increasing the resilience of its economy against external shocks, supporting employment creation and technological innovation, and adding do...
raisin is the second major export item in iranian agricultural section after pistachio. in this study, effects of exchange rate fluctuations were investigated on quantity and price of exported raisin. therefore, data of 1970 to 2008 were reviewed by time series analysis and estimated by auto-regressive distributed lag model (ardl). results show the absence of a long-term relationship between ex...
A comparative (15)N-tracer study of nitrogen dynamics in headwater streams from biomes throughout North America demonstrates that streams exert control over nutrient exports to rivers, lakes, and estuaries. The most rapid uptake and transformation of inorganic nitrogen occurred in the smallest streams. Ammonium entering these streams was removed from the water within a few tens to hundreds of m...
