Product Detail	Crystallins are the major proteins of the vertebrate eye lens, where they maintain the transparency and refractive index of the lens. Crystallins are divided into a, b, and g families, and the b- and g-crystallins also comprise a superfamily. Crystallins usually contain seven distinctive protein regions, including four homologous motifs, a connecting peptide, and N- and C-terminal extensions. b-crystallins constitute the major lens structural proteins. They associate into dimers, tetramers, and higher order aggregates. The b-crystallin subfamily is composed of several gene products, including bA1-, bA2-, bA3-, bA4-, bB1-, bB2- and bB3-crystallin. The bA1- and bA3-crystallin proteins are encoded by a single mRNA. They differ by only 17 amino acids, and bA1-crystallin is generated by use of an alternate translation initiation site. The genes for bA4-, bB1-, bB2- and bB3-crystallin are clustered on human chromosome 22q11, while the genes for bA3/A1- and bA2-crystallin map to human chromosomes 17q11 and 2q34, respectively. Function: Crystallins are the dominant structural components of the vertebrate eye lens. Subunit: Homo/heterodimer, or complexes of higher-order. Thestructure of beta-crystallin oligomers seems to be stabilizedthrough interactions between the N-terminal arms (By similarity). Post-translational modifications: Specific cleavages in the N-terminal arm occur during lens maturation and give rise to several truncated forms. Cleavages do not seem to have adverse effects on solubility. S-methylation and glutathionylation occur in normal young lenses and do not seem to be detrimental. Isoform A1 initiator methionine is removed. The new N-terminal amino acid is then N-acetylated. DISEASE: Defects in CRYBA1 are the cause of cataract congenital zonular with sutural opacities (CCZS) [MIM:600881]. A form of zonular cataract. Zonular or lamellar cataracts are concentric opacities, broad or narrow, usually consisting of powdery white dots affecting one lamella or zonule of an otherwise clear lens. Similarity: Belongs to the beta/gamma-crystallin family. Contains 4 beta/gamma crystallin 'Greek key' domains.
