Interleukin-20 receptor subunit alpha (IL20RA) is a key component of the interleukin-20 receptor complex, which belongs to the IL-10 receptor family. It plays a critical role in mediating cellular responses to cytokines IL-19. IL-20. and IL-24. which are involved in regulating inflammatory processes, epidermal functions, and tissue homeostasis. IL20RA is primarily expressed in epithelial cells, keratinocytes, and immune cells, where it activates downstream signaling pathways, including JAK-STAT (particularly STAT3), to modulate cell proliferation, differentiation, and immune regulation. Dysregulation of IL20RA signaling has been implicated in chronic inflammatory diseases (e.g., psoriasis, rheumatoid arthritis) and certain cancers, highlighting its therapeutic relevance.
Recombinant IL20RA protein is engineered to mimic the native receptor’s extracellular domain, typically produced in mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications, such as glycosylation. This protein often includes tags (e.g., Fc or His tags) for purification and detection. Its production involves transfection, affinity chromatography, and rigorous quality control to confirm bioactivity, stability, and low endotoxin levels.
Research applications of recombinant IL20RA include ligand-receptor interaction studies, pathway analysis, and drug screening. It serves as a tool to investigate mechanisms underlying skin disorders, autoimmune conditions, and tumor microenvironments. Additionally, it is used to develop therapeutic antibodies or decoy receptors targeting IL-20 cytokine signaling. As a standardized reagent, it aids in diagnostic assays and biomarker studies, bridging translational research and clinical innovation.
