Interleukin 12 receptor, beta 2 subunit
Interleukin 12 receptor, beta 2 subunit is a subunit of the interleukin 12 receptor. IL12RB2 is its human gene.[1] IL12RB2 orthologs [2] have been identified in all mammals for which complete genome data are available.
The protein encoded by this gene is a type I transmembrane protein identified as a subunit of the interleukin 12 receptor complex. The coexpression of this and IL12RB1 proteins was shown to lead to the formation of high-affinity IL12 binding sites and reconstitution of IL12 dependent signaling. The expression of this gene is up-regulated by interferon gamma in Th1 cells, and plays a role in Th1 cell differentiation. The up-regulation of this gene is found to be associated with a number of infectious diseases, such as Crohn's disease and leprosy, which is thought to contribute to the inflammatory response and host defense.[1]
Interactions
Interleukin 12 receptor, beta 2 subunit has been shown to interact with Janus kinase 2.[3]
RNA editing
