Cloning of canine IL-1ra, TNFR and TIMP-2.
This paper describes the cloning and sequence analysis of the cDNA's encoding the canine homologues of interleukin-1 receptor antagonist (IL-1ra), tumour necrosis factor receptor extra-cellular domain (TNFR/ECD) and tissue inhibitor of metalloproteinase-2 (TIMP-2). The coding sequences for canine IL-1ra and TNFR/ECD were obtained using reverse transcription polymerase chain reaction (RT-PCR) using RNA harvested from canine peripheral blood mononuclear cells (PBMC) and TIMP-2 was isolated in a similar fashion from the canine D17 osteosarcoma cell line. Sequence analysis of the canine genes demonstrated open reading frames of 531, 633 and 663 base pairs (bp), respectively. All three canine proteins IL-1ra, TNFR/ECD and TIMP-2 (177, 211 and 221 amino acids, respectively) showed considerable sequence similarity with the homologous sequences published for other species.
