Evolution of immunoglobulin kappa chain variable region genes in vertebrates.
The major source of immunoglobulin diversity is variation in DNA sequence among multiple copies of variable region (V) genes of the heavy- and light-chain multigene families. In order to clarify the evolutionary pattern of the multigene family of immunoglobulin light kappa chain V region (V kappa) genes, phylogenetic analyses of V kappa genes from humans and other vertebrate species were conduc...
متن کاملChromosomal location of human kappa and lambda immunoglobulin light chain constant region genes
The chromosomal location of human constant region light chain immunoglobulin (Ig) genes has been determined by analyzing a group of human fibroblast/rodent somatic cell hybrids with nucleic acid probes prepared from cloned human kappa and lambda constant region genes. Human chromosomes in each cell line were identified by isoenzyme analysis. The DNA from hybrid cells was digested with restricti...
متن کاملNomenclature of the human immunoglobulin kappa (IGK) genes.
'Nomenclature of the Human Immunoglobulin Kappa (IGK) Genes', the 17th report of the 'IMGT Locus in Focus' section, provides the first complete list of all the human IGK genes. In the most frequent haplotypes, the human IGK locus spans 1,820 kb and the IGKV genes are organized in two clusters separated by 800 kb. In those haplotypes where both the proximal and distal IGKV clusters are present, ...
متن کاملImmunoglobulin kappa light chain variable region gene complex organization and immunoglobulin genes encoding anti-DNA autoantibodies in lupus mice.
We have investigated the genetic origin of autoantibody production in several strains of mice that spontaneously develop a systemic lupus erythematosus-like disease. Restriction fragment length polymorphism analyses of gene loci encoding kappa light chain variable regions (Igk-V) demonstrated, as shown previously for the Ig heavy chain locus, that autoantibody production and disease occur in di...
متن کاملLocalization, analysis and evolution of transposed human immunoglobulin V" genes
The localization of V", gene regions to chromosome 2, on which the K locus is located, and to other chromosomes is described. The V", genes that have been transposed to other chromosomes are called orphons. The finding of two new V", genes on chromosome 22 is reported. A V", 11 gene of this region and two V", I genes of the Chr 1 and the cos 118 regions were sequenced. The two V", I orphon sequ...
