We engineered a photoactivatable system for rapidly and reversibly exporting proteins from the nucleus by embedding a nuclear export signal in the LOV2 domain from phototropin 1. Fusing the chromatin modifier Bre1 to the photoswitch, we achieved light-dependent control of histone H2B monoubiquitylation in yeast, revealing fast turnover of the ubiquitin mark. Moreover, this inducible system allo...

This paper provides a direct test of how fixed export costs and productivity jointly determine firm-level export behavior. Using Chilean data, we construct indices of fixed export costs for each industry-region-year triplet and match them to domestic firms. Our empirical results show that firms facing higher fixed export costs are less likely to export, while those with higher productivity expo...

The mRNA nuclear export receptor Mex67/Mtr2 is recruited to mRNAs through RNA-binding adaptors, including components of the THO/TREX complex that couple transcription to mRNA export. Here we show that the ubiquitin-associated (UBA) domain of Mex67 is not only required for proper nuclear export of mRNA but also contributes to recruitment of Mex67 to transcribing genes. Our results reveal that th...

The Prospero transcription factor promotes neural differentiation in Drosophila, and its activity is tightly regulated by modulating its subcellular localization. Prospero is exported from the nucleus of neural precursors but imported into the nucleus of daughter cells, which is necessary for their proper differentiation. Prospero has a highly divergent putative homeodomain adjacent to a conser...

This study examines the impact that various incentives to export have on the export marketing performance of Australian export market ventures. The incentives to export used in this study were adapted from Sullivan and Bauerschmidt (1990). The unit of analysis was Australian export market ventures engaged in exporting to foreign markets. Data were gathered via a self-administered mail survey di...

Strambio-De-Castilla, Caterina, "Jumping over the fence: RNA nuclear export revisited" (2013).

This study extends prior researches by exploring the effect of organizational orientations on export performance. Building on the already extensive literature, we developed a model of relationship. A total of 120 usable questionnaires were received from the Iranian food industry SMEs. The results indicated that entrepreneurial orientation, market orientation and learning orientation positively ...

I n this paper, the evaluation of the real exchange rate transfer and the asymmetric transmission of real exchange rate fluctuations to the export prices of food products for the country during the period (2001-2015) was studied using two approaches of PMG and GMM systems. The TGARCH method was used to calculate the real exchange rate fluctuation index and the Markov Switching method was u...

One of the goals of the government is to increase the competitiveness of domestic firms to export goods and services. Moreover, the role of exports in many economic sectors has been emphasized. There are two essential requirements for developing non-oil exports: first, the presence of firms in export markets and increasing their competitiveness; second, the survival of them in international mar...

this paper surveys the persian monetary crises due to economic sanctions and speculative attacks that leads to high inflation. economic sanctions are associated with various forms of trade barriers and restriction on financial transactions. among the most influential sanctions on iran's oil export and central bank sanctions are noted that their aims to reduce iran's oil revenues and devaluation...
