| Function
Crystalline is found in the lens of the eye accounting for the transparency and probably increasing the refractive index of it. α-, β-, γ-, δ-crystalline are named according to the order they are eluted by gel filtration. δ-crystalline is found in avian and reptilian lenses.[1]
Disease
Several human cataracts have been linked to mutations in γ-D-crystalline[2].
