PTB Proteins Induce RNA Looping
Lamichhane, Daubner et al., PNAS
Researchers in the US and Switzerland report that polypyrimidine tract-binding proteins induce RNA looping ― a finding they deduced using FRET, NMR spectroscopy, and in vivo splicing data. They show that two PTB RNA recognition motifs can bind two distant pyrimidine tracts, bringing their 5' and 3' ends in close proximity, thus inducing loop formation.
Royal Society of Chemistry Buys ChemSpider as Open Access Chem Resources Gain Momentum
The news of the ChemSpider buyout by the RSC is "great news, not only for ChemSpider but the chemistry community in general," Rajarshi Guha, co-founder of the open source cheminformatics group Blue Obelisk, told BioInform this week.
