Antigens, CDw121b

An Interleukin-1 receptor subtype that competes with the Interleukin-1 Receptor Type I for binding to Interleukin-1alpha and Interleukin-1beta. The Interleukin-1 type II receptor appears to lack Signal Transduction capability. Therefore it may act as a "decoy" receptor that modulates the activity of its Ligands. Both Membrane-bound and soluble Forms of the receptor have been identified.
