Abstract: | A new gene for the variable region of the immunoglobulin heavy chain (VH gene) has been isolated from BALB/c adult liver DNA using a cDNA plasmid probe containing a mouse VH sequence. The complete nucleotide sequence of this germline gene (VH10-19), shows that it belongs to the 7183 gene family. The VH gene appears to contain an intervening 104-base-long sequence and displays the same recombination signal sequences that those observed in the germline 81X. The presence of an internal heptamer at the 3' end of the VH10-19 coding region let an alternative recombination event that could increase the representation of this gene in the immature repertoire. |
