Rat immunoglobulin delta heavy chain gene: nucleotide sequence derived from cloned cDNA
Gene
|December 1, 1982
Abstract:
Rat immunoglobulin delta heavy-chain mRNA has been isolated. RNA blot analysis revealed that this mRNA with a length of 1.8 kb encodes for the secreted form of IgD. The corresponding cDNA was cloned in plasmid pBR322 and its sequence was determined. The hybrid plasmid contains a 775-bp insert comprising a partial C delta 1 sequence and complete C delta H, C delta 3, C delta DC and 3' untranslated sequences. Rat and mouse IgD amino acid sequences show striking homology in C delta 3 and C delta DC regions.
