生化机理 | Interleukin 2 was initially identified as a T cell growth factor that is produced by T cells following activation by mitogens or antigens. Since then, it has been shown that IL-2 can also stimulate the growth and differentiation of B cells, natural killer (NK) cells, lymphocyte activated killer (LAK) cells, monocytes/macrophages, and oligodendrocytes. The biological activity of IL-2 is mediated by the binding to cell surface receptor complexes composed of three subunits designated as alpha, beta, and gamma subunits. IL-2 binds the alpha subunit with low affinity. The functional high affinity IL-2 receptor is a heterotrimeric complex of the alpha, beta, and gamma subunits. IL-2 binds with intermediate affinity to the complex containing the beta and gamma subunits, which is also capable of transducing IL-2 signals. In T cells, the beta and gamma subunits are shared with the IL-15 receptor complex. The gamma subunit of the IL-2 receptor complex has also been shown to be a subunit of the receptor complexes of IL-4, IL-7, and IL-9. At the amino acid sequence level, canine IL-2 shares 90%, 86%, 85%, 76%, and 75% sequence similarities to feline, human, equine, mouse, and bovine IL-2, respectively. |

Recombinant Canine IL-2 (C147S) Protein (rp186528) - SDS-PAGE
3 μg/lane of Recombinant Canine IL-2 (C147S) Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 13.3 kDa under reducing conditions and 11.9 & 26.3 kDa under non-reducing conditions.
Under specific non-physiological conditions, including high concentrations or particular buffer environments, IL-2 monomers have the potential to form non-covalent dimers or higher-order oligomers through non-covalent interactions (Uniprot ID: Q29416).
