The alpha B-crystallin gene (CRYA2) encodes the abundant lens protein alpha B-crystallin. A panel of human/rodent hybrid cell lines, derived from five different parental combinations, was characterized with respect to human chromosomal content and the presence of well-established human chromosome-specific markers. This panel was screened for the presence of CRYA2, using the third exon of the hamster alpha B-crystallin gene as a probe. The patterns of segregation of CRYA2 with individual human chromosomes show the highest degree of concordance between CRYA2 and chromosome 11. Using cell hybrids containing translocated and/or partially deleted human chromosomes, the CRYA2 gene was localized to 11q12-11q23.

D002880 Chromosomes, Human, Pair 11 A specific pair of GROUP C CHROMOSOMES of the human chromosome classification. Chromosome 11
D003459 Crystallins A heterogeneous family of water-soluble structural proteins found in cells of the vertebrate lens. The presence of these proteins accounts for the transparency of the lens. The family is composed of four major groups, alpha, beta, gamma, and delta, and several minor groups, which are classed on the basis of size, charge, immunological properties, and vertebrate source. Alpha, beta, and delta crystallins occur in avian and reptilian lenses, while alpha, beta, and gamma crystallins occur in all other lenses.
