Product Description | Recombinant Biotinylated Cynomolgus IL-2 R beta/CD122 Protein (Primary Amine Labeling) is expressed from HEK293 with His tag at the C-Terminus.; It contains Ala27-Asp239. |
Product Background |
IL-2 R beta is a member of the cytokine receptor superfamily. Human IL-2 R beta cDNA encodes a 551 amino acid residue precursor Type I membrane protein with a 26 residue signal peptide, a 214 residue extracellular region, a 25 residue transmembrane region and a 286 residue cytoplasmic domain. Functional IL-2 receptors can exist in two affinity states on cell surfaces, the high affinity complex consisting of heterotrimers of the alpha, beta, and gamma chains, and the intermediate affinity complex comprising heterodimers of the beta and gamma chains. |
