1H, 13C, and 15N assignments of wild-type human γS-crystallin and its cataract-related variant γS-G18V
We present the backbone and sidechain NMR assignments and a structural analysis of the 178-residue wild-type γS-crystallin and the cataract-related point mutant, γS-G18V. γS-crystallin is a structural component of the eye lens, which maintains its solubility and stability over many years. NMR assignments and continued structural investigations of γS-crystallin and aggregation-prone variants will advance understanding of cataract formation.
