蛋白结构(Molecular Characterization)

IL-2 R beta & IL-2 R gamma Structure

Human IL-2RB&IL-2RG Heterodimer Protein, Fc Tag&Fc Tag is produced by co-expression of IL-2RB and IL-2RG, has a calculated MW of 51.1 kDa (IL-2RB) and 53.6 kDa (IL-2RG). Subunit IL-2RB is fused with a human IgG1 Fc tag at the C-terminus and subunit IL-2RG is fused with a human IgG1 Fc tag at the C-terminus. The reducing (R) protein migrates as 60-65 kDa and 70-75 kDa respectively due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

背景(Background)

Both Interleukin-2 receptor subunit beta and Interleukin-2 receptor subunit gamma are receptor for interleukin-2. Common subunit for the receptors for a variety of interleukins. Interacts with SHB upon interleukin stimulation. Probably in association with IL15RA, involved in the stimulation of neutrophil phagocytosis by IL15. This beta subunit is involved in receptor mediated endocytosis and transduces the mitogenic signals of IL2. IL2R exists in 3 different forms: a high affinity dimer, an intermediate affinity monomer (beta subunit), and a low affinity monomer (alpha subunit). The high and intermediate affinity forms also associate with a gamma subunit.
