It is a type I transmembrane protein present on activated T cells, activated B cells, some thymocytes, myeloid precursors, and oligodendrocytes that associates with CD122 to form a heterodimer that can act as a high-affinity receptor for IL-2.
CD25 expressed in most B-cell neoplasms, some acute nonlymphocytic leukemias, neuroblastomas, and tumor infiltrating lymphocytes.
Its soluble form, called sIL-2R may be elevated in these diseases and is occasionally used to track disease progression.
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 currently unknown.
