Several factors contribute to nuclear mRNA export in Saccharomyces cerevisiae, including Mex67p, Mtr2p, Gle1p, Nup159p, Dbp5p, and Rip1p. Strains carrying mutations in these factors show rapid and dramatic nuclear accumulation of poly(A)(+) RNA. We have characterized two heat shock mRNAs, SSA4 and HSP104, in these mutant backgrounds; each transcript concentrates in a single intranuclear focus. ...

Iran`s pharmaceutical products market as one of the major markets of the country has been faced with fluctuations over time. Suitable market selection is necessary for stability of pharmaceutical exports. Study of the global market structure of this product leads to policy makers in development, production, and trade of pharmaceuticals and finally increases country’s share of the world pharmace...

Nucleo-cytoplasmic transport of proteins is mediated by nuclear export signals, identified in various proteins executing heterologous biological functions. However, the molecular mechanism underlying the orchestration of export is only poorly understood. Using microinjection of defined recombinant export substrates, we now demonstrate that leucine-rich nuclear export signals varied dramatically...

in the present study, competitiveness of iranian pistachio exports and competitor countries in  the world market are studied. pistachio export advantage using indices of revealed comparative advantage (rca) approach and vector error correction model(vecm) based on  agricultural and non-petroleum export commodity basket were investigated separately. the results showed that iran has a comparative...
