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.
Tale of Danaher: From Crippled Real Estate Investment Trust to Mass Spec Top Banana
Few in proteomics had probably ever heard of Danaher until two weeks ago. But the once-struggling real estate investment trust has been transformed by the Rales brothers into a successful global conglomerate, and by the end of the year is poised to become the top mass-spec firm in the world with the purchase of the ABI/MDS joint venture.
