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.
Affy Sets Sights on Downstream Market to Offset GWA Studies 'Trough'
To make up for the "lumpiness" of the market for genome-wide association studies, Affy will focus on applications that are downstream from GWAS, particularly in validation and routine testing, according to President and CEO Kevin King, who also shed some light on Affy's recent decision to sell its Clinical Services Laboratory to Navigenics.
