NMR Detection Methods for Profiling RAS Nucleotide Cycling

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...
