Family relationships



The interleukin-2 receptor is a heterotrimer composed of one alpha chain, one beta chain, and one gamma chain, all of which are in contact with the ligand when the receptor is occupied [PMID: 2688708]. IL-2 itself has been shown to regulate IL-2R alpha expression in vitro [PMID: 9712069].
