ABSTRACT:
A soluble receptor to IL-20 having two polypeptide subunits, IL-20RA (formerly called ZcytoR7) and IL-20RB (formerly called DIRS1). The two subunits are preferably linked together. In one embodiment one subunit is fused to the constant region of the light chain of an immunoglobulin, and the other subunit is fused to the constant region of the heavy chain of the immunoglobulin. The light chain and the heavy chain are connected via a disulfide bond.
