MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the type II cytokine receptor family. The encoded protein is a subunit of the receptor for interleukin 20, a cytokine that may be involved in epidermal function. The interleukin 20 receptor is a heterodimeric complex consisting of the encoded protein and interleukin 20 receptor beta. This gene and interleukin 20 receptor beta are highly expressed in skin, and are upregulated in psoriasis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit increased bone mineral density, impaired osteoclast differentiation, and resistance to ovariectomized-inducced bone loss. [provided by MGI curators]

Protein Function and Prediction

Il20ra is a alternative splicing production of the Il20r1 gene, which associates with Il20rb to form the Il20 receptor type I (IL-20-RI), a receptor that mediates the activities of IL-19 subfamily of cytokines  (1-3). Il20ra is a soluble protein that can directly associate with mesangial cells to facilitate the phosphorylation of AKT and C-Jun N-terminal kinase (JNK) (4).  It is proposed that IL-20ra stimulates the production of chemoattractants, renal fibrogenic factors and reactive oxygen species (ROS) by mesangial cells (4).  In a transgenic mouse line that expressed full-length mIl20ra with a His tag, Wei et al (2009) proposed that mIL-20R1a is involved in calcium deposits associated with the pathogenesis of renal stone formation (5).


The IL-20-RI receptor is expressed mainly in the skin, lung, various glands, and the reproductive organs (1-3).
