Interleukin 20 receptor, alpha subunit is a subunit for the interleukin-20 receptor. IL20RA is its human gene.^[1]

The protein encoded by this gene is a receptor for interleukin 20 (IL20), a cytokine that may be involved in epidermal function. The receptor of IL20 is a heterodimeric receptor complex consisting of this protein and interleukin 20 receptor beta (IL20B). This gene and IL20B are highly expressed in skin. The expression of both genes is found to be upregulated in Psoriasis.^[1]
