Gene: IL2RA (interleukin 2 receptor subunit alpha) Homo sapiens
Symbol: IL2RA
Name: interleukin 2 receptor subunit alpha
Description: Contributes to interleukin-2 receptor activity. Involved in regulation of T cell tolerance induction. Predicted to localize to the interleukin-2 receptor complex. Implicated in lymphopenia; multiple sclerosis; primary immunodeficiency disease; type 1 diabetes mellitus; and type 1 diabetes mellitus 10. Biomarker of hemorrhagic fever with renal syndrome and idiopathic pulmonary fibrosis.
Type: protein-coding
RefSeq Status: REVIEWED
