Target Details for CD25

Target: CD25 (IL2RA) (Interleukin 2 Receptor, alpha (IL2RA))

Alternative Name: CD25/IL-2sR alpha

Background:

Background: CD25 is the alpha chain of the IL-2 receptor. 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. The IL2R gene was mapped to 10p15-p14. CD25 is 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.

Gene Full Name: interleukin 2 receptor subunit alpha
