NMR analyses of the interaction between the FYVE domain of early endosome antigen 1 (EEA1) and phosphoinositide embedded in a lipid bilayer.

ABSTRACT: Phosphoinositides (PIs) are crucial lipid components of membranes and are involved in a number of cellular processes through interactions with their effector proteins. Recently, we have established a lipid-protein nanoscale bilayer (nanodisc) containing PIs, hereafter referred to as PI-nanodisc and demonstrated that it could be used for both qualitative and quantitative evaluations of protein-membrane interactions. Here, we report further NMR analyses for obtaining structural insights at the residue-specific level between PI-binding effector protein and PI-nanodisc, using the FYVE domain of early endosome antigen 1 (EEA1), denoted as EEA1 FYVE, and PI(3)P-nanodisc as a model system. We performed a combination of the NMR analyses including chemical shift perturbation, transferred cross-satu
