Interleukin-20 receptor subunit beta (IL20RB) is also known as IL-20R2, DIRS1, which belongs to the type II cytokine receptor family. IL20RB / IL-20R2 contains two fibronectin type-III domains. IL20RB / IL-20R2 is widely expressed with highest levels in skin and testis. IL20RB can be fused with IL20RA or IL22RA1 forming heterodimer. The IL20RA/IL20RB dimer is a receptor for IL19, IL20 and IL24. The IL22RA1/IL20RB dimer is a receptor for IL20 and IL24. This protein fused with Fc fragment of human IgG1 at the C-terminus, has a calculated MW of 49.1 kDa. The predicted N-terminus is Asp 30. As a result of glycosylation, DTT-reduced Protein migrates as 50 kDa and non-reduced protein migrates as 100 kDa. Purity ≥90%
