Interleukin 6 receptor alpha (IL-6Rα) is a Type I transmembrane protein and Type I cytokine receptor. The recombinant IL-6Rα dimer protein (CSP-25224-01) is a cis-homodimer (cis-dimer) and contains an IL-6Rα extracellular domain (UniProt# P22272, amino acids Leu20-Pro364) fused with a proprietary cis-dimer motif followed by a His tag at the C-terminus. This dimeric protein is expressed in HEK293T cells. The recombinant mouse IL-6Rα dimer protein is bioactive and can bind to interleukin 6 (IL-6). It also binds IL-6Rα-specific antibodies. This IL-6Rα dimer can be used as an antigen for in vitro assays and antibody screening, and as an immunogen for immunization to generate antibodies targeting more conformational epitopes.

Protein Name: IL6R

UniProt #: P22272

Predicted Molecular Weight: 92 kDa

SDS PAGE Molecular Weight: The migration range of the dimer protein with glycosylation under non-reducing condition is between 120 and 190 kDa on SDS PAGE.

Protein Construct: IL-6Rα protein dimer contains the IL-6Rα extracellular domain (UniProt# P22272) fused with a proprietary cis-dimer motif followed by a His tag at the C-terminus.

Background

Interleukin 6 receptor alpha (IL-6Rα) is a Type I transmembrane protein and Type I cytokine receptor and plays a crucial role in immune response, inflammation, and hematopoiesis. IL-6Rα is also known as Cluster of Differentiation 126 (CD126), IL6R, CD126, IL-6R-1, IL-6RA, IL6Q, IL6RA, IL6RQ, and gp80. IL-6Rα contains an extracellular domain with an Ig-like domain, cytokine binding module (CBM) domains, and a long flexible stalk region followed by a transmembrane domain and intracellular domains. IL-6Rα binding to its ligand interleukin 6 (IL-6) results in homodimerization and subsequent association with IL-6Rβ (gp130) dimer resulting in higher order complexes. IL-6Rα is involved in multiple disease processes due to its central role in IL-6 signaling. Dysregulation of IL-6Rα is implicated in many cancers and autoimmune diseases. While structurally and functionally similar to mouse IL-6Rα, mouse IL-6Rα is a species-specific tool essential for preclinical studies, basic research and translational research in cancer immunotherapy.
