An Error has occurred retrieving Wikidata item for infobox Interleukin-12 receptor, beta 1, or IL-12Rβ1 in short, is a subunit of the interleukin 12 receptor. IL12RB1, is the name of its human gene.[1] IL-12Rβ1 is also known as CD212 (cluster of differentiation 212).

The protein encoded by this gene is a type I transmembrane protein that belongs to the hemopoietin receptor superfamily.

This protein binds to interleukin-12 (IL-12) with a low affinity, and is part of the IL-12 receptor complex. This protein forms a disulfide-linked oligomer, which is required for its IL-12 binding activity. The coexpression of this and IL-12Rβ2 protein was shown to lead to the formation of high-affinity IL-12 binding sites and reconstitution of IL-12 dependent signaling.

IL-12Rβ1 can also bind interleukin-23 (IL-23) as part of the IL-23 receptor complex. This complex forms a disulfide-linked oligomer, which is required for its IL-23 binding activity. The coexpression of this and IL-23R protein was shown to lead to the formation of IL-23 binding sites.

Various mutations in this gene were found to result in the immunodeficiency of patients with severe mycobacterial and Salmonella infections.[2] Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.[1]

All mutations known in the IL12RB1 gene, as well as many polymorphisms, have been collected in a mutation database [3][4]
