The generation of the recombinant Human IL12RB1 protein involves manipulating gene expression in baculovirus cells. A specific DNA sequence coding for the Human IL12RB1 protein (24-545aa) is inserted to an expression vector, which is then introduced into baculovirus cells. The cells that successfully receive the vector are selected and cultured to induce the expression of the desired protein. A C-terminal 6xHis tag is attached to the protein. The recombinant Human IL12RB1 protein undergoes affinity purification, achieving a purity level exceeding 85%, as verified through SDS-PAGE analysis.

Target Background

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.
