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.
In Picking Up Affy's CLIA Lab is Navigenics Inviting More Regulatory Woes?
Navigenics decided to acquire Affy’s 10,000-square-foot Clinical Services Lab in Sacramento, Calif., after seeing an increase in the volume of orders for its genetic screening service. In addition to the advantages of having an internal CLIA lab, however, the consumer genomics firm will now have to navigate a complex regulatory environment.
