Interleukin-17 receptor A (IL17RA) is a key component of the IL-17 receptor family, playing a pivotal role in mediating inflammatory and immune responses. As a type I transmembrane protein, it consists of an extracellular domain, a single transmembrane region, and a cytoplasmic signaling domain. IL17RA serves as a common subunit for multiple IL-17 receptor complexes, including those binding IL-17A, IL-17F, and IL-17A/F heterodimers. Its activation triggers downstream signaling pathways such as NF-κB and MAPK, leading to the production of pro-inflammatory cytokines, chemokines, and antimicrobial peptides. This receptor is broadly expressed in epithelial, endothelial, and immune cells, linking innate and adaptive immunity.
Recombinant IL17RA protein is typically produced using mammalian expression systems (e.g., CHO or HEK293 cells) to ensure proper post-translational modifications and functional integrity. The purified protein often includes fusion tags like Fc or His for enhanced stability and detection. Researchers utilize IL17RA recombinant proteins to study receptor-ligand interactions, screen therapeutic agents, and investigate autoimmune diseases such as psoriasis, rheumatoid arthritis, and multiple sclerosis. Its soluble form has shown potential as a decoy receptor to neutralize excessive IL-17 signaling in pathological conditions.
Recent studies highlight IL17RA's involvement in host defense against fungal and bacterial infections, as well as its dual role in promoting both tissue repair and chronic inflammation. The development of IL17RA-targeted biologics, including monoclonal antibodies and fusion proteins, has emerged as a promising strategy for immune-mediated disorders. Structural characterization of recombinant IL17RA has provided insights into its ligand-binding epitopes and dimerization mechanisms, facilitating the design of next-generation immunotherapies. Quality control of the recombinant protein typically involves SDS-PAGE, Western blot, and functional assays using IL-17-responsive cell lines to confirm bioactivity.
