• Product Overview: Recombinant Cynomolgus/Rhesus macaque IL4R protein (Met26-Arg232), fused to human IgG1 Fc tag at C-terminus, was expressed in human 293 cells (HEK293).In the region Met26-Arg232, the AA sequence of Cynomolgus and Rhesus macaque IL4R are homologus.

Specification

• Description: IL-4 is a pleiotropic cytokine produced by activated Th2 cells and mast cells, and plays a pivotal role in immune responses. The effects of IL-4 are mediated after binding to high affinity receptor complexes present on hematopoietic as well as non-hematopoietic cells. Hematopoietic cellular responses to IL-4 are mediated by a high affinity receptor complex comprised of the 140 kDa IL4Rα (CD124) subunit and the 70 kDa common cytokine γc chain (CD132).
  Interleukin 4 Receptor (IL4R) also known as CD124, IL4Rα and BSF receptor, is a type I cytokine receptor produced by activated Th2 cells and mast cells, and plays an important role in Th2-­biased immune responses, alternative macrophage activation, mucosal immunity, allergic inflammation, tumor progression, and atherogenesis. A soluble form of the encoded IL4R protein can be produced by an alternate splice variant or by proteolysis of the membrane-bound protein, and this soluble form can inhibit IL4-mediated cell proliferation and IL5 upregulation by T-cells. IL4R can alternatively associate with IL­13Ra1 to form the type II receptor which is responsive to both IL­4 and IL­13. Interleukin-4 receptor has been shown to interact with SHC1.

Q&As

How about function of IL4R?

IL4R is a synthetic protein that mimics the IL-4 signaling pathway in nature and binds to the IL-4 receptor in cells, which can be used to study the IL-4 signaling pathway and related diseases.

What is the production technology of IL4R?

Common IL4R production technologies include prokaryotic expression systems and mammalian cell expression systems.

Which application of IL4R in tumor therapy?

This protein is used in tumor immunotherapy, which can promote anti-tumor immune response and enhance the anti-tumor effect of cytotoxic T lymphocytes.

In what fields does IL4R have applications?

It is mainly used in immunology, drug research and other fields. It is also widely used in vaccines, biotechnology, cancer treatment and so on.

Are there have application of IL4R in the treatment of asthma?

IL4R is used to treat severe pheochromocytome-induced aerodoritis and was approved by the FDA as the first drug to treat this disease.

Can IL4R be administered orally?

IL4R cannot generally be administered orally, and needs to be administered by injection or intravenous drip.
