      Background InformationAlpha B-crystallin is a major structural protein in the vertebrate eye lens, but is also found in cardiac and skeletal muscles, kidney, and brain. Alpha B-crystallin is also found to be a component of Rosenthal fibers and a consistent tissue marker of epileptic foci. It occurs as large aggregates of up to 106 Da, composed of two proteins, αA- and αB-crystallin. The αA gene encodes a polypeptide of 173 residues, while αB-crystallin gene encodes a 175 residue polypeptide. αB-crystallin, like the small heat shock proteins (sHsp's), is induced by heat or osmotic shock and is upregulated by stress. α-crystallin and the sHsp's protect other proteins from heat-induced aggregation. The two other crystallin families, β and ɣ, are homologous to each other but not to the α-family or the sHsp's.

      Entrez Gene Number
      Entrez Gene SummaryCrystallins are separated into two classes: taxon-specific, or enzyme, and ubiquitous. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. Since lens central fiber cells lose their nuclei during development, these crystallins are made and then retained throughout life, making them extremely stable proteins. Mammalian lens crystallins are divided into alpha, beta, and gamma families; beta and gamma crystallins are also considered as a superfamily. Alpha and beta families are further divided into acidic and basic groups. Seven protein regions exist in crystallins: four homologous motifs, a connecting peptide, and N- and C-terminal extensions. Alpha crystallins are composed of two gene products: alpha-A and alpha-B, for acidic and basic, respectively. Alpha crystallins can be induced by heat shock and are members of the small heat shock protein (sHSP also known as the HSP20) family. They act as molecular chaperones although they do not renature proteins and release them in the fashion of a true chaperone; instead they hold them in large soluble aggregates. Post-translational modifications decrease the ability to chaperone. These heterogeneous aggregates consist of 30-40 subunits; the alpha-A and alpha-B subunits have a 3:1 ratio, respectively. Two additional functions of alpha crystallins are an autokinase activity and participation in the intracellular architecture. Alpha-A and alpha-B gene products are differentially expressed; alpha-A is preferentially restricted to the lens and alpha-B is expressed widely in many tissues and organs. Elevated expression of alpha-B crystallin occurs in many neurological diseases; a missense mutation cosegregated in a family with a desmin-related myopathy.
