Gene

IL2RA

Species
Homo sapiens
Symbol
IL2RA
Name
interleukin 2 receptor subunit alpha
Synonyms
  • CD25
  • IDDM10
Biotype
protein coding gene
Automated Description
Enables interleukin-2 receptor activity. Involved in interleukin-2-mediated signaling pathway and regulation of T cell tolerance induction. Predicted to be located in plasma membrane. Predicted to be part of interleukin-2 receptor complex. Implicated in immunodeficiency 41; lymphopenia; multiple sclerosis; type 1 diabetes mellitus; and type 1 diabetes mellitus 10. Biomarker of COVID-19; Hantavirus hemorrhagic fever with renal syndrome; and idiopathic pulmonary fibrosis.
RGD Description
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. Patients with severe Coronavirus Disease 2019 (COVID-19), the disease caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have significantly elevated levels of IL2R in their plasma. Similarly, serum IL-2R levels are found to be elevated in patients with different types of carcinomas. Certain IL2RA and IL2RB gene polymorphisms have been associated with lung cancer risk.
