The T cell receptor beta chain genes are located on chromosome 6 in mice and chromosome 7 in humans.
Homologous clones that encode the beta chain of the T cell antigen receptor have been isolated recently from both murine and human cDNA libraries. These cDNA clones have been used in connection with interspecies hybrid cell lines to determine that the murine T cell receptor gene is located on chromosome 6 and the human gene on chromosome 7. In situ hybridization confirms these data and further localizes these genes to band B of chromosome 6 in the mouse and bands 7p13-21 in the human genome. The organization of the T cell antigen receptor J beta gene segments and C beta genes appears to be conserved, since very few intraspecies polymorphisms of restriction fragment length have been detected in either mouse or human DNA.
