||Interleukin 1 receptor type II (IL1R2), also known as CD121b (Cluster of Differentiation 121b), is a transmembrane protein found on B lymphocytes, neutrophils, monocytes, large granular leukocytes and endothelial cells. It is a decoy receptor known for its ability to buffer IL-1 effects. IL-1RII is involved in the control of the proinflammatory state that takes place in the endometrium during the premenstrual and menstrual periods. IL-1RII can neutralize IL-1 beta and counteract its effect on endometrial stromal cells, and may provide a new clinical strategy for the treatment of endometriosis.
||The predicted molecular weight of Recombinant Mouse IL-1 RII is Mr 64.7 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 70-80 kDa.
