摘要: Immune systems of vertebrates function via two types effector cells, B and T which are capable antigen-specific recognition. The immunoglobulins, serve as antigen receptors on have been well characterized with respect to gene structure, unlike the T-cell receptors. Recently, cDNA clones thought correspond beta-chain locus human mouse receptor described. presumptive detect rearrangement specifically in DNA show homology immunoglobulin light chains. similarity system genes has further demonstrated by recent observation variable- constant-region segments joining putative diversity segments. We report here characterization genomic encoding genes. There (C beta 1 C 2), each expression RNA. arrangement, analogous that genes, shows strong evolutionary conservation dual these species.
