Protein Information (annotations from UniProt)

Database IDHIV0009649
UniProt IDP01589
Primary gene name(s)IL2RA
Synonym gene name(s)unknown
Protein nameInterleukin-2 receptor subunit alpha
Protein functionReceptor 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. {ECO:0000269|PubMed:23416241, ECO:0000269|PubMed:24116927}.
Subcellular locationMembrane;
Single-pass type I membrane protein.
