AbstractThe α‐crystallin family of small heat shock proteins possesses chaperone activity in response to stress and is involved in several neurological, muscular, and ophthalmic pathologies. This family includes the vertebrate lens protein α‐crystallin, associated with cataract disease. In this study, by combining small‐angle X‐ray and light scattering techniques, the structure and shape of α‐crystallin was revealed in its native state and after a transition caused by heat stress. Below critical temperature (Tc), α‐crystallin appears as an ellipsoid with a central cavity; whereas at high temperatures the cavity almost disappears, and the protein rearranges its structure, increasing the solvent‐exposed surface while retaining the ellipsoidal symmetry. Contextually, at Tc, α‐crystallin chaperone binding shows an abrupt increase. By modelling the chaperone activity as the formation of a complex composed of α‐crystallin and an aggregating substrate, it was demonstrated that the increase of α‐crystallin‐exposed surface is directly responsible for its gain in chaperone functionality.

Ranked by citation count — the same ordering the engine uses when summing log1p(Cq) over citers.
DataRank blends this paper's own citation count with the influence of the papers that cite it. Here, roughly 48% comes from its base citations and 52% from the citation network (9 citing papers contributed measurable signal).
Citers are pulled from OpenAlex sorted by cited_by_count:descand capped per paper, so when the cap binds we keep the highest-signal references and the score is reproducible across reruns.
