Disease

[I12R1_HUMAN] Primary biliary cholangitis;Mendelian susceptibility to mycobacterial diseases due to complete IL12RB1 deficiency. The disease is caused by variants affecting the gene represented in this entry.

Function

[I12R1_HUMAN] Functions as an interleukin receptor which binds interleukin-12 with low affinity and is involved in IL12 transduction. Associated with IL12RB2 it forms a functional, high affinity receptor for IL12. Associates also with IL23R to form the interleukin-23 receptor which functions in IL23 signal transduction probably through activation of the Jak-Stat signaling cascade.^[1]

Publication Abstract from PubMed

Interleukin-12 (IL-12) and IL-23 are heterodimeric cytokines that are produced by antigen-presenting cells to regulate the activation and differentiation of lymphocytes, and they share IL-12Rbeta1 as a receptor signaling subunit. We present a crystal structure of the quaternary IL-23 (IL-23p19/p40)/IL-23R/IL-12Rbeta1 complex, together with cryoelectron microscopy (cryo-EM) maps of the complete IL-12 (IL-12p35/p40)/IL-12Rbeta2/IL-12Rbeta1 and IL-23 receptor (IL-23R) complexes, which reveal "non-canonical" topologies where IL-12Rbeta1 directly engages the common p40 subunit. We targeted the shared IL-12Rbeta1/p40 interface to design a panel of IL-12 partial agonists that preserved interferon gamma (IFNgamma) induction by CD8(+) T cells but impaired cytokine production from natural killer (NK) cells in vitro. These cell-biased properties were recapitulated in vivo, where IL-12 partial agonists elicited anti-tumor immunity to MC-38 murine adenocarcinoma absent the NK-cell-mediated toxicity seen with wild-type IL-12. Thus, the structural mechanism of receptor sharing used by IL-12 family cytokines provides a protein interface blueprint for tuning this cytokine axis for therapeutics.

Structural basis for IL-12 and IL-23 receptor sharing reveals a gateway for shaping actions on T versus NK cells.,Glassman CR, Mathiharan YK, Jude KM, Su L, Panova O, Lupardus PJ, Spangler JB, Ely LK, Thomas C, Skiniotis G, Garcia KC Cell. 2021 Feb 18;184(4):983-999.e24. doi: 10.1016/j.cell.2021.01.018.
