| abstractText | The human homologue of the recently cloned murine IL-13 binding protein (IL-13R alpha1) was cloned from a cDNA library derived from the carcinoma cell line CAKI-1. The cloned cDNA encodes a 427 amino acid protein with two consensus patterns characteristic of the hematopoietic cytokine receptor family and a short cytoplasmic tail. The human protein is 74% identical to the murine IL-13R alpha1, and 27% identical to the human IL-13R alpha2. CHO cells expressing recombinant hIL-13R alpha1 specifically bind IL-13 (Kd approximately 4 nM) but not IL-4. Co-expression of the cloned cDNA with that of IL-4R alpha resulted in a receptor complex that displayed high affinity for IL-13 (Kd approximately 30 pM), and that allowed cross-competition of IL-13 and IL-4. Electrophoretic mobility shift assay showed that IL-13 and IL-4 were able to activate Stat6 in cells expressing both IL-4R alpha and IL-13R alpha1, while no activation was observed in cells expressing either one or the other alone. |
