Crystallins
WebWhile the critical function of corneal crystallins has yet to be established, the fact that the lens and cornea are unique in being transparent has prompted the hypothesis that they form a structural unit, the ‘refracton’, that has evolved through a process of gene sharing to meet the demands required for the development and maintenance of … WebAlpha-crystallin Alpha A and alpha B-crystallins are a major protein component of the mammalian eye lens. Being a member of the small heat-shock protein family they possess chaperone-like function. The alpha-crystallins and especially alpha B is also found outside the lens having an extensive tissue distribution. Al …

WebDec 1, 2012 · Crystallins are the abundant, long-lived proteins of the eye lens. The major human crystallins belong to two different superfamilies: the small heat-shock proteins (α … Webα-Crystallins are small heat-shock proteins that act as holdase chaperones. In humans, αA-crystallin is expressed only in the eye lens, while αB-crystallin is found in many tissues. α-Crystallins have a central domain flanked by flexible extensions and form dynamic, heterogeneous oligomers.
WebMay 22, 2001 · However, the γ crystallins differ from the α and β crystallins in one important respect: the interactions between the γ crystallins are attractive . This feature reduces the osmotic pressure in the lens, but it also makes the γ crystallins more susceptible to aggregation and phase separation, phenomena that diminish the … WebCrystallins are the main constituent of the lens and are separated into three types in vertebrates: α, β and γ-crystallins [ 6, 7 ]. α-Crystallin is the predominant and biggest type of crystallins, with a molecular weight around 800 kDa [ 6 ].
WebNov 26, 2024 · Crystallins—α, β and γ constitute approximately 90% of all lens proteins and the major soluble proteins in the newborn lens. They are also responsible for the refractive index (RI) gradient of the lens, but they can also be membrane-associated and this increases with age [ 6 ]. WebFeb 10, 2024 · In order for crystallins to be packed tightly in lens fibre cells, they must be folded stably and correctly.

WebMar 1, 1999 · We also note that ALDH1 accumulates in the rabbit corneal epithelial cells, rather than ALDH3 as seen in other mammals, consistent with the taxon-specificity observed among lens enzyme-crystallins. Our results suggest that corneal cells, like lens cells, may preferentially express water-soluble proteins, often enzymes, for controlling their ...
