Swiss-port # P01589 Human Interleukin-2 receptor subunit alpha |
|---|---|
| Gene Symbol | IL2RA |
| Gene Full Name | interleukin 2 receptor, alpha |
| Background | The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. Normally an integral-membrane protein, soluble IL2RA has been isolated and determined to result from extracellular proteolyisis. Alternately-spliced IL2RA mRNAs have been isolated, but the significance of each is presently unknown. Mutations in this gene are associated with interleukin 2 receptor alpha deficiency.

| Function | Receptor 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. [UniProt] |
| Cellular Localization | Membrane; Single-pass type I membrane protein. [UniProt] |
| Calculated MW | 31 kDa |
