It may be used as a positive control in various immunological assays.
Target Information
IL12B (IL-12 p40) encodes a subunit of interleukin 12, a cytokine that acts on T and natural killer cells and has diverse biological activities.
Interleukin 12 is a disulfide-linked heterodimer composed of a 40 kDa cytokine receptor-like subunit encoded by this gene and a 35 kDa subunit encoded by IL12A.
This cytokine is expressed by activated macrophages and is essential for Th1 cell development. It helps maintain memory/effector Th1 cells for long-term protection against intracellular pathogens.
Overexpression of IL12B has been observed in the central nervous system of patients with multiple sclerosis (MS), suggesting a role in disease pathogenesis.
Promoter polymorphisms of IL12B are associated with the severity of atopic and non-atopic asthma in children.
