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.
MDS Completes Sale of Late-Stage Pharma Services Group
MDS announced its plans to sell the business to INC for $50 million in early June as part of a broader strategy to focus the MDS Pharma Services business on services for early-stage discovery through Phase IIa, where it said it holds a "top-three" position in the market.
