Nina Ripin, who spent some months in the lab as a Masters’ student in 2011, is the lead author on a nice study focused on the RNA-binding properties of HuR in the latest PNAS. She has combined NMR and X-ray crystallography while working in Fred Allain’s lab at ETH in Zurich to characterize the means by which this protein uses its RRM domains to bind to AU-rich RNA elements.
