Abstract:
A single contig spanning the entire mouse immunoglobulin kappa light chain (Igk) locus on chromosome 6 has been established using yeast and bacterial artificial chromosome clones. Detailed mapping of the Igk locus indicates that a member of the Igk-V2 gene family, located about 3.5 megabases upstream of the Igk-J-C complex, is the most distal functional Igk-V gene. Sequence analyses of Igk-V genes and anonymous DNA segments provide indications for internal duplications at the 5' end of the Igk-V locus and identify the likely origin of Igk-V orphon gene clusters located elsewhere in the mouse genome.
