Polyamine-Mediated Stoichiometric Assembly of Ribonucleoproteins for Enhanced mRNA Delivery by Li, Jiahe, He, Yanpu, Wang, Wade, Wu, Connie, Hong, Celestine, Hammond, Paula T

“…Inspired by the dependence of mRNA on 3′-terminal polyadenosine nucleotides (poly A) and poly A binding proteins (PABPs) for optimal expression, we complexed synthetic mRNA containing a poly A tail with PABPs in a stoichiometric manner and stabilized the ribonucleoproteins (RNPs) with a family of polypeptides bearing different arrangements of cationic side groups. We found that the molecular structure of these polypeptides modulates the degree of PABP-mediated enhancement of mRNA expression. …”

Crystal structures of asymmetric ClpX hexamers reveal nucleotide-dependent motions in a AAA+ protein-unfolding machine by Glynn, Steven E., Martin, Andreas, Nager, Andrew Ross, Baker, Tania, Sauer, Robert T

“…These differences prevent nucleotide binding to two subunits, generate a staggered arrangement of ClpX subunits and pore loops around the hexameric ring, and provide a mechanism for coupling conformational changes caused by ATP binding or hydrolysis in one subunit to flexing motions of the entire ring. …”

Solid-state NMR evidence for inequivalent GvpA subunits in gas vesicles by Sivertsen, Astrid C., Bayro, Marvin J., Belenky, Marina, Griffin, Robert Guy, Herzfeld, Judith

“…The gas vesicle shell consists almost exclusively of the hydrophobic 70-residue gas vesicle protein A, arranged in an ordered array. Solid-state NMR spectra of intact collapsed gas vesicles from the cyanobacterium Anabaena flos-aquae show duplication of certain gas vesicle protein A resonances, indicating that specific sites experience at least two different local environments. …”

A complex network of factors with overlapping affinities represses splicing through intronic elements by Wang, Yang, Xiao, Xinshu, Zhang, Jianming, Choudhury, Rajarshi, Li, Kai, Ma, Meng, Wang, Zefeng, Robertson, Alex De Jong, Burge, Christopher B

“…Many factors bound multiple distinct motifs with similar affinity, and all motifs were recognized by multiple factors, which revealed a complex overlapping network of protein-RNA interactions. This arrangement enables individual cis elements to function differently in distinct cellular contexts, depending on the spectrum of regulatory factors present.…”

Design rules for self-assembled block copolymer patterns using tiled templates by Chang, Jae-Byum, Choi, Hong Kyoon, Hannon, Adam F., Alexander-Katz, Alfredo, Ross, Caroline A., Berggren, Karl K, Alexander-Katz, Alfredo

“…The block copolymer patterns resulting from all tile arrangements are determined. By combining tiles in different ways, it is possible to predict a relatively simple template that will direct the formation of non-trivial block copolymer patterns, providing a new template design method for a complex block copolymer pattern.…”

Planar integrated metasurfaces for highly-collimated terahertz quantum cascade lasers by Liang, Guozhen, Dupont, Emmanuel, Fathololoumi, Saeed, Wasilewski, Zbigniew R., Ban, Dayan, Liang, Hou Kun, Zhang, Ying, Yu, Siu Fung, Li, Lianhe H., Davies, Alexander Giles, Linfield, Edmund H., Liu, Hui Chun, Wang, Qi Jie

“…We report planar integration of tapered terahertz (THz) frequency quantum cascade lasers (QCLs) with metasurface waveguides that are designed to be spoof surface plasmon (SSP) out-couplers by introducing periodically arranged SSP scatterers. The resulting surface-emitting THz beam profile is highly collimated with a divergence as narrow as ~4° × 10°, which indicates a good waveguiding property of the metasurface waveguide. …”
