The bottle-nosed dolphin (Tursiops truncatus) interleukin-1 receptor antagonist IL-1ra cDNA was cloned from mitogen-stimulated peripheral blood mononuclear cells (PBMC) RNA utilizing the reverse transcription-polymerase chain reaction (RT-PCR). The sequence of this cDNA showed that dolphin IL-1ra clones contained open reading frames encoding 177 amino acids. Comparison of the deduced amino acids showed that dolphin IL-1ra sequence shared 87.6, 77.9, 77.4, 77.4, 76.4, and 75.8% similarity with the bovine, rabbit, equine, human, mouse, and rat IL-1ra sequences, respectively. Recombinant glutathione S-transferase (GST) dolphin IL-1ra produced in Escherichia coli (E. coli) was purified. This protein suppressed the cytostatic activity of dolphin IL-1beta on A375S2 cells, indicating that the dolphin IL-1ra cDNA obtained in the present study encodes biologically active dolphin IL-1ra.
