Summaries for IL12RB2 Gene

Entrez Gene Summary for IL12RB2 Gene

  • 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. Several transcript variants encoding different isoforms and non-protein coding transcripts have been found for this gene. [provided by RefSeq, Apr 2012]

GeneCards Summary for IL12RB2 Gene

IL12RB2 (Interleukin 12 Receptor Subunit Beta 2) is a Protein Coding gene. Diseases associated with IL12RB2 include Sinusitis and Lepromatous Leprosy. Among its related pathways are Akt Signaling and Immune response_IL-12 signaling pathway. Gene Ontology (GO) annotations related to this gene include protein kinase binding and cytokine receptor activity. An important paralog of this gene is CSF3R.

UniProtKB/Swiss-Prot for IL12RB2 Gene

  • Receptor for interleukin-12. This subunit is the signaling component coupling to the JAK2/STAT4 pathway. Promotes the proliferation of T-cells as well as NK cells. Induces the promotion of T-cells towards the Th1 phenotype by strongly enhancing IFN-gamma production.

    Quaternary structure:
    • Heterodimer/heterooligomer; disulfide-linked. The functional high affinity IL12 receptor is composed of I12RB1 and IL12RB2. Il12RB2 binds JAK2 (via its N-terminal) through a membrane-proximal region of the cytoplasmic domain. Interaction, in vitro and in vivo, with SOCS3 (via its SH2 domain) inhibits the STAT4-mediated activation. Binds STAT4 through a membrane-distal C-terminal region.
