Transparency in the eye lens is maintained via specific, functional interactions among the structural betagamma- and chaperone alpha-crystallins. Here, we report the structure and alpha-crystallin binding interface of the G18V variant of human gammaS-crystallin (gammaS-G18V), which is linked to hereditary childhood-onset cortical cataract. Comparison of the solution nuclear magnetic resonance structures of wild-type and G18V gammaS-crystallin, both presented here, reveal that the increased aggregation propensity of gammaS-G18V results from neither global misfolding nor the solvent exposure of a hydrophobic residue but instead involves backbone rearrangement within the N-terminal domain. alphaB-crystallin binds more strongly to the variant, via a well-defined interaction surface observed via chemical shift differences. In the context of the alphaB-crystallin structure and the finding that it forms heterogeneous multimers, our structural studies suggest a potential mechanism for cataract formation via the depletion of the finite alphaB-crystallin population of the lens.
