Solution NMR spectroscopy reveals the energy landscape of immature Cu, Zn-superoxide dismutase and leads to atomic resolution structural models of transiently populated non-native oligomers.

The human eye lens imports and concentrates within itself a naturally abundant small molecule that inhibits cataract-associated aggregation of an eye lens protein before the aggregates get large enough to scatter light.
Ca2+-free synaptotagmin-1 binds to neuronal SNARE complexes anchored on nanodiscs, and Ca2+ releases this interaction to induce tight, specific binding to PIP2-containing membranes.

The intermediate state conformation of the human KCNQ1 potassium channel voltage sensor domain was determined, validated, and shown to be conductive under physiological conditions.

Generation of a highly deuterated 13C-methyl labeled wild-type GPCR sample is used to facilitate characterization of the molecular environments and fast ps-ns dynamics of sidechains when the receptor is bound to ligands of different efficacy.

A comprehensive allosteric model describes how inhibitors can activate rather than inhibit a target kinase by selectively driving formation of kinase dimers with one inhibited and one activated subunit.
A cargo recognition α-helix was identified in Nup358, which is required for activation of a dynein-dependent transport pathway that is essential for brain development.

Plasma membrane clusters of the Parkinson's disease protein α-synuclein colocalize with negatively charged phospholipids involved in endocytosis and exocytosis.
Conservative mutations within a secondary active transport protein influenced the conformational equilibrium probed using NMR spectroscopy which correlated to the functional output in vivo.
