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. The level of IL2/IL2R in plasma has been found to be elevated in some patients with severe COVID-19, but decreased in critical patients. [provided by RefSeq, Jun 2020]
GeneCards Summary for IL2RA Gene
IL2RA (Interleukin 2 Receptor Subunit Alpha) is a Protein Coding gene.

Among its related pathways are RET signaling and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include drug binding and interleukin-2 binding.
UniProtKB/Swiss-Prot Summary for IL2RA Gene
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.
Cytokines are proteinaceous signaling compounds that are major mediators of the immune response. They control many different cellular functions including proliferation, differentiation and cell survival/apoptosis but are also involved in several pathophysiological processes.
