Summaries for IL2RA Gene

Entrez Gene Summary for IL2RA Gene

  • 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.[provided by RefSeq, Nov 2009]

GeneCards Summary for IL2RA Gene

IL2RA (Interleukin 2 Receptor Subunit Alpha) is a Protein Coding gene. Diseases associated with IL2RA include Immunodeficiency 41 With Lymphoproliferation And Autoimmunity and Diabetes, Mellitus, Insulin-Dependent 10. Among its related pathways are HTLV-I infection and p70S6K Signaling. GO annotations related to this gene include drug binding and interleukin-2 binding.

UniProtKB/Swiss-Prot 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.

Tocris Summary for IL2RA Gene

  • 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.

  • Diabetes mellitus, insulin-dependent, 10 (IDDM10) [MIM:601942]: A multifactorial disorder of glucose homeostasis that is characterized by susceptibility to ketoacidosis in the absence of insulin therapy. Clinical features are polydipsia, polyphagia and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels. {ECO:0000269 PubMed:17676041}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
  • Immunodeficiency 41 with lymphoproliferation and autoimmunity (IMD41) [MIM:606367]: A disorder of immune dysregulation characterized by recurrent viral, fungal, and bacterial infections, lymphadenopathy, and variable autoimmune features, such as autoimmune enteropathy and eczematous skin lesions. {ECO:0000269 PubMed:23416241, ECO:0000269 PubMed:24116927}. Note=The disease is caused by mutations affecting the gene represented in this entry.
