Synonymes: CD25 Protein, IDDM10 Protein, IL2R Protein, TCGFR Protein, IL2RAC Protein, IL-2RA Protein, Il2r Protein, Ly-43 Protein, interleukin 2 receptor subunit alpha Protein, interleukin-2 receptor subunit alpha-like Protein, interleukin 2 receptor, alpha chain Protein, IL2RA Protein, Il2ra Protein, LOC100222957 Protein

Sujet: IL-2 receptor alpha (IL-2 R alpha), also known as Tac antigen and as CD25, was initially identified as a 55 kDa membrane glycoprotein that is capable of binding IL-2.eceptor for interleukin-2. The receptor is involved in the regulation of immune tolerance by controlling regulatory T cells (TREGs) activity. TREGs suppress the activation and expansion of autoreactive T-cells.

Poids moléculaire: 25.76 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.

UniProt: P01590

Pathways: Signalistation JAK/STAT, Growth Factor Binding, Activated T Cell Proliferation
