It contains 1 fibronectin type-III domain and 1 Ig-like C2-type domain. IL-12B is a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. IL-12 is a disulfide-linked heterodimer composed of the 40 kD cytokine receptor encoded by IL12B and a 35 kD subunit encoded by IL12A. IL12 is expressed by activated macrophages that serve as an essential inducer of Th1 cells development. It has been found to be important for sustaining a sufficient number of memory\/effector Th1 cells to mediate long-term protection to an intracellular pathogen.\u003c\/p\u003e\n\n\u003cp\u003eActivity: Measured in a cell proliferation assay using PHA-activated human peripheral blood lymphocytes (PBMC).
