IL-6R Protein, Canine (HEK293, His)
Based on 1 Customer Validation
IL-6R alpha is a subunit alpha of IL-6 receptors, also shared by other interleukin receptors. IL-6R alpha acts as IL-6 agonist and involves in JAK/STAT, MAPK, and Akt signaling pathway. IL-6R alpha, Canine consists of 462 amino acids (M1-R462) and is produced in HEK293 cells with a C-Terminal His-tag.

Biological Activity
Description
IL-6R alpha is a subunit alpha of IL-6 receptors, also shared by other interleukin receptors. IL-6R alpha acts as IL-6 agonist and involves in JAK/STAT, MAPK, and Akt signaling pathway[1][2]. IL-6R alpha, Canine consists of 462 amino acids (M1-R462) and is produced in HEK293 cells with a C-Terminal His-tag.
Background
IL-6 acts as both inflammatory factor and anti-inflammatory factor, fuels cancer progression through activating a series of downstream signalling cascade including gp130 (dimers), JAK/STAT, MAPK, and Akt[1][2].
IL-6R alpha (IL-6Rα) as a part of the receptor for interleukin 6, is a type I transmembrane glycoprotein, which forms a complex with the type I transmembrane signal transducer Glycoprotein 130 (CD130) and regulates the biological activity of IL-6 with a low affinity[3].
IL-6R alpha has 2 isoform including mIL6R (the longer one) or sIL6R (the shorter one):
The mIL6R is membrane-bound interleukin-6 receptor, has the potential to drive naive CD4+ T cells to the Th17 lineage, through 'cluster signaling' by dendritic cells[4].
The sIL-6R is soluble interleukin-6 receptor subunit, cleaved from IL-6R alpha (IL-6Rα) in activated CD4+ T cells by proteolysis, and serves as IL-6 agonist. sIL-6R binds membrane-bound IL6R and subunit IL6ST to activate regenerative and anti-inflammatory signal via IL-6 trans signaling and promotes pro-inflammatory properties of IL-6. The hydrolysis of IL-6R alpha is also called ectodomain shedding[1].
IL-6R alpha involves in regulating cell growth and differentiation, and plays an important role in regulation of immune response, acute-phase reactions and hematopoiesis[5].
However, IL-6R alpha shows tissue expression specificity in liver and some cells of the immune system, thus results a limitation of IL6 signaling[6].
It's worth noting that IL-6R alpha dysregulation is implicated in the pathogenesis of many diseases, such as multiple myeloma, autoimmune diseases, and prostate cancer[7][8].
Verified Bioactivity
Measured by its binding ability in a functional ELISA.Immobilized canine IL6R-His at 10 μg/mL (100 μL/well) can bind human IL6, the EC50 of human IL6 is 5-50 ng/mL.
