RAS oncoproteins exhibit a switch-like behavior to drive diverse signaling cascades. In the active GTP-bound state, a conformational change occurs in these enzymes that enables interaction with downstream effectors. Nucleotide-dependent conformational exchange is easily detected with real-time NMR (RT-NMR) spectroscopy. RT-NMR has been firmly established as an effective assay to measure RAS oncoprotein nucleotide exchange and GTP hydrolysis kinetics and can further determine the regulatory...

[NMR paper] Novel methods based on 13C detection to study intrinsically disordered proteins
Novel methods based on 13C detection to study intrinsically disordered proteins
Publication date: April 2014

Author(s): Isabella C. Felli , Roberta Pierattelli</br>
Intrinsically disordered proteins (IDPs) are characterized by highly flexible solvent exposed backbones and can sample many different conformations. These properties confer them functional advantages, complementary to those of folded proteins, which need to be characterized to expand our view of how protein structural and dynamic features affect...

Abstract
The duration and amplitude of G-protein-coupled receptor (GPCR) signaling is controlled by regulator of G-protein signaling (RGS) proteins. The 20 RGS family members act as GTPase accelerating proteins through their interaction with the G? subunit of the G??? heterotrimer. Their influence over GPCR signaling has attracted many to...
