Anti-Human ST2 Purified No Carrier Protein (Clone: 97203)

ST2 belongs to the immunoglobulin superfamily and bears significant amino acid identity (~25%) to the extracellular portion of both type I and type II interleukin 1 receptors (IL-1R). Some of the intracellular residues that are required for signal transduction through the IL-1R and are conserved in the Drosophila Toll protein are also found in the membrane form of ST2. Furthermore, the gene for ST2 was mapped to mouse chromosome 1 closely linked to the il-1r locus containing both type I and type II receptor genes in support of their common ancestry.
