Background

NCI Identification Number:

10408

Antigen Name:

Crystallin Alpha B

CPTC Name:

CPTC-CRYAB

Aliases:

CRYAB; Alpha(B)-crystallin; CRYA2; CTPP2; HSPB5; HspB5

Function:

Crystallins 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.
