Description
Product Characteristics: CD25 is a 55 kDa glycoprotein, also known as the low affinity IL-2Ralpha, Ly-43, p55, or Tac. It is expressed on activated T and B cells, thymocyte subset, pre-B cells, and T regulatory cells. association with CD122 (IL-2Rbeta) and CD132 (common gamma chain), CD25 forms the high affinity signaling IL-2 receptor. The PC61 antibody is able to block IL-12 binding to its receptor and inhibit IL-2 stimulated cell growth.
Target Information: The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. 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 presently unknown. Mutations in this gene are associated with interleukin 2 receptor alpha deficiency.[provided by RefSeq, Nov 2009]
