Description of Recombinant Mouse CD125/IL5RA Protein, N-His

Introduction

Recombinant Mouse CD125/IL5RA Protein, also known as Interleukin-5 Receptor Alpha (IL5RA), is a protein that plays a crucial role in the immune system. It is a type I transmembrane protein that is expressed on the surface of various immune cells, including B cells, T cells, and eosinophils. This protein is encoded by the IL5RA gene and is involved in the binding and signaling of Interleukin-5 (IL-5), a cytokine that regulates the growth and differentiation of eosinophils and other immune cells.

Structure of Recombinant Mouse CD125/IL5RA Protein

The Recombinant Mouse CD125/IL5RA Protein is a 60 kDa protein that consists of 443 amino acids. It has a single transmembrane domain, a short cytoplasmic tail, and a large extracellular domain. The extracellular domain contains several conserved regions, including a cytokine receptor homology domain (CRH), a fibronectin type III domain, and a WSXWS motif. These regions are important for ligand binding and signal transduction.

Activity of Recombinant Mouse CD125/IL5RA Protein

The main function of Recombinant Mouse CD125/IL5RA Protein is to bind to IL-5 and initiate downstream signaling pathways. IL-5 binds to the CRH domain of the protein, leading to the dimerization of IL5RA with the IL-5 receptor beta subunit (IL-5RB). This dimerization activates the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway, resulting in the phosphorylation of STAT5 and the induction of gene transcription. This signaling pathway is crucial for the survival, proliferation, and activation of eosinophils, which play a role in allergic and inflammatory responses.

In addition to its role in IL-5 signaling, Recombinant Mouse CD125/IL5RA Protein has also been shown to interact with other cytokines, such as IL-3 and granulocyte-macrophage colony-stimulating factor (GM-CSF). This interaction can modulate the activity of IL-5 and enhance the survival and activation of eosinophils and other immune cells.

Application of Recombinant Mouse CD125/IL5RA Protein

Recombinant Mouse CD125/IL5RA Protein has a wide range of applications in both research and clinical settings. In research, this protein is commonly used as an antigen to study the structure and function of IL-5 and its receptor. It is also used to investigate the role of IL-5 signaling in various diseases, including asthma, allergies, and parasitic infections.

In clinical settings, Recombinant Mouse CD125/IL5RA Protein has potential therapeutic applications. As IL-5 is a key cytokine involved in the development and maintenance of eosinophilic disorders, targeting the IL-5/IL5RA signaling pathway has been explored as a treatment option. Recombinant Mouse CD125/IL5RA Protein can be used to block IL-5 signaling and inhibit the survival and activation of eosinophils. This approach has shown promising results in clinical trials for the treatment of severe asthma and eosinophilic disorders, such as eosinophilic esophagitis and hypereosinophilic syndrome.

Conclusion

In summary, Recombinant Mouse CD125/IL5RA Protein is a crucial protein involved in the immune system, specifically in the binding and signaling of IL-5. Its structure, activity, and applications have been extensively studied and have provided valuable insights into the role of IL-5 signaling in various diseases. With its potential therapeutic applications, this protein continues to be a subject of interest for researchers and clinicians alike.
