beta Crystallins

A class of Crystallins that provides refractive Power and translucency to the lens (Lens, Crystalline) in Vertebrates. Beta-Crystallins are similar in structure to gamma-Crystallins in that they both contain Greek key motifs. Beta-Crystallins exist as oligomers formed from acidic (beta-Crystallin A Chain) and basic (beta-Crystallin B Chain) subunits.
