||Recombinant human CRYGS protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques (1-178 aa).
||Crystallins are water soluble structural proteins found in the vertebrate eye. Mammalian crystallins are classified in three forms, designated alplha, beta and gamma. Crystallins, as the principal components of the lens, function to increase the refractive index of the eye during accommodation by forming high-molecular weight aggregates which maintain transparency. CRYGS, also known as beta-crystallin S, is exists as a monomer which does not aggregate. This gene encodes the most significant gamma-crystallin in adult eye lens tissue. Whether due to aging or mutations in specific genes, gamma-crystallins have been involved in cataract formation.
