NCIt definition : Interleukin-12 receptor subunit beta-1 (662 aa, 73 kDa) is encoded by the human IL12RB1
gene. This protein plays a role in interleukin-12 binding and signal transduction.;
NCIt note : Interleukin-12 receptor subunit beta-1 is a type I transmembrane disulfide-linked
dimer/oligomer containing 5 fibronectin type-III domains, a box 1 motif required for
JAK interaction/activation, and a WSXWS motif for protein folding, intracellular transport,
and cell-surface receptor binding. IL12RB1 oligomers act as a low affinity IL12 receptor;
the high affinity IL12 receptor is composed of IL12RB1 and IL12RB2. Heterodimers containin
one IL12RB1 and one IL23R are receptors for interleukin-23. (UniProt);
