The adaptor protein Nmd3 is required for Crm1-dependent export of large ribosomal subunits from the nucleus. In this issue, Sengupta et al. (2010. J. Cell Biol. doi:10.1083/jcb.201001124) identify a binding site for yeast Nmd3 on 60S ribosomal subunits using cryoelectron microscopy and suggest a conformational model for its release in the cytoplasm. The study provides the first detailed structu...

This work proposes a subwavelength porous meta-liner with broadband sound absorption from 900 to 1,200 Hz. The consists of four subunits, which are made up material and hollow coiling slit embedded in it. Each subunit is designed by adjusting the length its achieve resonance target frequency examined finite element method (FEM). These subunits arranged an axial direction uniformly radial period...

Inflammatory molecules sensitize peripheral nociceptors, making them responsive to innocuous stimuli. Sensitization is mediated by protein kinase A (PKA), but the ion channels involved are not known. PKA increases expression of voltage-gated sodium channels, but knock-out of these channels does not eliminate inflammation-induced sensitization. PKA also decreases potassium currents, but the perc...

seed protein quality is an important topic in the production of soybean. the quality of soybean proteins is limited by anti-nutrient proteins and low levels of essential sulfur amino acids. in this study, protein content and solubility of six cultivars were evaluated and seed storage proteins were analyzed using sds-page and scanning densitometry. the results showed that seed storage protein ba...

Respiratory chain complexes in mitochondria are assembled from subunits derived from two genetic systems. For example, the bc(1) complex consists of nine nuclear encoded subunits and the mitochondrially encoded subunit cytochrome b. We recently showed that the Cbp3-Cbp6 complex has a dual function for biogenesis of cytochrome b: it is both required for efficient synthesis of cytochrome b and fo...

G protein-coupled receptor (GPCR)-Galpha fusion proteins were first characterized more than 10 years ago as a strategy for studying receptor-G protein signaling. A large number of studies have used this approach to characterize receptor coupling to members of the Gs, Gi, and Gq families of Galpha subunits, but this strategy has not been widely used to study Galpha12 and Galpha13. As described i...

The formation of the large protein structure known as "gluten" during dough-mixing and bread-making processes is extremely complex. It has been established that a specific subset of the proteins comprising gluten, the glutenin subunits, directly affects dough formation and breadmaking quality. Glutenin subunits have no definitive structural differences that can be directly correlated to their a...

Detailed global gene expression profiles have been obtained for a series of transgenic and conventionally bred wheat lines expressing additional genes encoding HMW (high molecular weight) subunits of glutenin, a group of endosperm-specific seed storage proteins known to determine dough strength and therefore bread-making quality. Differences in endosperm and leaf transcriptome profiles between ...

The inhibitory glycine receptor (nomenclature as agreed by the NC-IUPHAR Subcommittee on Glycine Receptors) is a member of Cys-loop superfamily transmitter-gated ion channels that includes zinc activated channels, GABAA, nicotinic acetylcholine and 5-HT3 receptors Zn2+- channels. expressed either homo-pentamer α subunits, or complex now thought to harbour 2α 3β subunits [33, 7], contain an intr...

Hemoglobin is a tetrameric oxygen transport protein in animal bodies. However, there is a paucity of information regarding differences between alpha and beta subunits of hemoglobin in terms of oxygen affinity. The sequential model of Koshland, Nemthy and Filmer (KNF model) has attributed similar affinities to both alpha and beta subunits. The main purpose of the present study is to construct a ...
