Advanced Science, 2023 Positioned within the eye, the lens supports vision by transmitting and focusing light onto the retina. As an adaptive glassy material, the lens is constituted primarily by densely‐packed, polydisperse crystallin proteins that organize to resist ...

αA-crystallin peptide SDRDKFVIFLDVKHF accumulating in aging lens impairs the function of α-crystallin and induces lens protein aggregation. [PDF]
PLoS ONE, 2011 The eye lens is composed of fiber cells that are filled with α-, β- and γ-crystallins. The primary function of crystallins is to maintain the clarity of the lens through ordered interactions as well as through the chaperone-like function of α-crystallin.

New insight into cataract formation -- enhanced stability through mutual attraction [PDF]
, 2007 Small-angle neutron scattering experiments and molecular dynamics simulations combined with an application of concepts from soft matter physics to complex protein mixtures provide new insight into the stability of eye lens protein mixtures.

Interaction of βA3-Crystallin with Deamidated Mutants of αA- and αB-Crystallins.
PLoS ONE, 2015 Interaction among crystallins is required for the maintenance of lens transparency. Deamidation is one of the most common post-translational modifications in crystallins, which results in incorrect interaction and leads to aggregate formation.

Strain-independent increases of crystallin proteins in the retina of type 1 diabetic rats. [PDF]
PLoS ONE, 2013 Diabetic retinopathy is the leading cause of vision loss in working-age individuals in the United States and is expected to continue growing with the increased prevalence of diabetes. Streptozotocin-induced hyperglycemia in rats is the most commonly used

Data in Brief, 2020 The interaction of αA- and αB-crystallins with Cu2+ ion modulates their structure and chaperone-like activity which is important for lens transparency. Theoretical analysis of the dependences of fluorescence intensity of native αA- and αB-crystallins and

Local variation in absolute water content of human and rabbit eye lenses measured by Raman microspectroscopy [PDF]
, 1989 Raman spectra were obtained from fresh, fixed and sliced rabbit lenses and from human lens slices. For all lenses and lens slices the ratio R, defined as the Raman intensity at 3390 cm−1 divided by the Raman intensity at 2935 cm−1, was measured at ...

Small heat-shock proteins: important players in regulating cellular proteostasis [PDF]
, 2015 Small heat-shock proteins (sHsps) are a diverse family of intra-cellular molecular chaperone proteins that play a critical role in mitigating and preventing protein aggregation under stress conditions such as elevated temperature, oxidation and infection.
