title: [The structure of the variable gene for the kappa chains of antibodies produced by hybridoma PTF-02].
abstract: The genome of hybridoma PTF-02 has two genes for the kappa chains, and only one of these codes for the synthesis of the antibody light chains. The nucleotide sequences corresponding to the leader peptide and to the variable region of this gene were determined. An amino acid sequence corresponding to exons has been proposed on the basis of the nucleotide sequence. A nucleotide sequence adjacent to the gene at the 5'-end has also been determined, in particular, the precise localization of TATA- and CAT-boxes as well as those of the conservative deca (dc) and pentadeca (pd) sequences. The structure of the regulatory region in the gene is similar to that in the myeloma genomes. However, the 5'-region differs in its nucleotide composition and in the frequency of dc sequences from the DNA sequences adjacent to the 5'-end of eukaryotic genes which do not belong to the immunoglobulin family.
