Interleukin 2 receptor subunit alpha
Sign in to saveAlso known as TAC antigen, interleukin-2 receptor subunit alpha, p55, IL-2 receptor subunit alpha, IL2RA, IL-2R subunit alpha, interleukin 2 receptor, alpha, CD25
The interleukin-2 receptor alpha chain (also called Tac antigen, P55, and mainly CD25) is a protein involved in the assembly of the high-affinity interleukin-2 receptor, consisting of alpha (IL2RA), beta (IL2RB) and the common gamma chain (IL2RG). As the name indicates, this receptor interacts with interleukin-2, a pleiotropic cytokine which plays an important role in immune homeostasis.

== Genetics == The human protein interleukin-2 receptor subunit alpha is encoded by a gene called IL2RA with a length around 51,6 kb. Alternative names for this protein coding gene are IL2R, IDDM10 and TCGFR. Location of IL2RA in human genome is on the short arm of 10th chromosome (10p15.1).
