Description

IL-17RA serves as the signaling receptor for IL-17A and IL-17F, making it a critical node in Th17-driven inflammatory pathways and a validated therapeutic target. This recombinant human IL-17RA construct spans the extracellular ligand-binding domain (aa 33–320) with a C-terminal Fc tag, and its mammalian cell expression ensures native glycosylation and proper disulfide-mediated folding essential for conformational epitope presentation. Functional ELISA confirms binding activity with an ED50 of 13.50 ng/ml against an anti-human IL-17RA monoclonal antibody, supporting use in blocking antibody screening, therapeutic antibody epitope mapping, ligand-receptor interaction assays by SPR or BLI, and as a positive control in binding studies. Endotoxin levels below 1.0 EU/μg combined with greater than 90% purity by SDS-PAGE satisfy the quality thresholds commonly required for drug discovery screening of small-molecule or biologic inhibitors targeting the IL-17 signaling axis.

Target Background

Function

Receptor for IL17A and IL17F, major effector cytokines of innate and adaptive immune system involved in antimicrobial host defense and maintenance of tissue integrity. Receptor for IL17A. Receptor for IL17F. Binds to IL17A with higher affinity than to IL17F. Binds IL17A and IL17F homodimers as part of a heterodimeric complex with IL17RC. Also binds heterodimers formed by IL17A and IL17F as part of a heterodimeric complex with IL17RC. Cytokine binding triggers homotypic interaction of IL17RA and IL17RC chains with TRAF3IP2 adapter, leading to TRAF6-mediated activation of NF-kappa-B and MAPkinase pathways, ultimately resulting in transcriptional activation of cytokines, chemokines, antimicrobial peptides and matrix metalloproteinases, with potential strong immune inflammation. Involved in antimicrobial host defense primarily promoting neutrophil activation and recruitment at infection sites to destroy extracellular bacteria and fungi. In secondary lymphoid organs, contributes to germinal center formation by regulating the chemotactic response of B cells to CXCL12 and CXCL13, enhancing retention of B cells within the germinal centers, B cell somatic hypermutation rate and selection toward plasma cells. Plays a role in the maintenance of the integrity of epithelial barriers during homeostasis and pathogen infection. Stimulates the production of antimicrobial beta-defensins DEFB1, DEFB103A, and DEFB104A by mucosal epithelial cells, limiting the entry of microbes through the epithelial barriers. Involved in antiviral host defense through various mechanisms. Enhances immunity against West Nile virus by promoting T cell cytotoxicity. Contributes to Influenza virus clearance by driving the differentiation of B-1a B cells, providing for production of virus-specific IgM antibodies at first line of host defense. Receptor for IL17C as part of a heterodimeric complex with IL17RE.; (Microbial infection) Receptor for SARS coronavirus-2/SARS-CoV-2 virus protein ORF8, leading to IL17 pathway activation and an increased secretion of pro-inflammatory factors through activating NF-kappa-B signaling pathway.
