Importin-beta: structural and dynamic determinants of a molecular spring.
The beta-karyopherin/RanGTP system constitutes the largest known family of cellular cargo transporters. The flexibility of the karyopherin transport receptors is the key to their versatility in binding cargoes of different shape and size. Despite strong binding of the Ran complex, the comparably low energy associated with GTP hydrolysis suffices to drive dissociation and fuel the transport cycl...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولThe Ketel gene encodes a Drosophila homologue of importin-beta.
The Drosophila melanogaster Ketel gene was identified via the Ketel(D) dominant female sterile mutations and their ketel(r) revertant alleles that are recessive zygotic lethals. The maternally acting Ketel(D) mutations inhibit cleavage nuclei formation. We cloned the Ketel gene on the basis of a common breakpoint in 38E1. 2-3 in four ketel(r) alleles. The Ketel(+) transgenes rescue ketel(r)-ass...
متن کاملImportin beta negatively regulates nuclear membrane fusion and nuclear pore complex assembly.
Assembly of a eukaryotic nucleus involves three distinct events: membrane recruitment, fusion to form a double nuclear membrane, and nuclear pore complex (NPC) assembly. We report that importin beta negatively regulates two of these events, membrane fusion and NPC assembly. When excess importin beta is added to a full Xenopus nuclear reconstitution reaction, vesicles are recruited to chromatin ...
متن کاملMutation of SAD2, an importin beta-domain protein in Arabidopsis, alters abscisic acid sensitivity.
A number of protein and RNA-processing mutants have been shown to affect ABA sensitivity. A new mutant, sad2-1, was isolated from a T-DNA mutagenized population of RD29A:LUC plants and shown to have increased luminescence after ABA, salt, cold or polyethylene glycol treatments. Expression of several ABA- and stress-responsive genes was higher in the mutant than in the wild type. sad2-1 also exh...
