UniProt data
UniProt name: I12R1_HUMAN (P42701)
Gene name: IL12RB1; Synonyms=IL12R, IL12RB
Organism: Homo sapiens (Human).
Function: 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. {ECO:0000269|PubMed:12023369}.
Subcellular location: Membrane; Single-pass type I membrane protein.
Transmembrane domains:
- 546-570, 25 AA, Helical. {ECO:0000255}.
Sequence: 662 AA
