IL18R1 - interleukin 18 receptor 1 Gene
Also Known as CD218a; IL18RA; IL1RRP; CDw218a; IL-1Rrp; IL-18Ralpha; IL18Ralpha2; IL-18R-alpha
Species: Homo sapiens
About IL18R1
This gene has 5 transcripts (splice variants), 211 orthologues and 10 paralogues. Broad expression in appendix (RPKM 4.6), gall bladder (RPKM 3.7) and 21 other tissues.
Summary
The protein encoded by this gene is a cytokine receptor that belongs to the interleukin 1 receptor family. This receptor specifically binds interleukin 18 (IL18), and is essential for IL18 mediated signal transduction. IFN-alpha and IL12 are reported to induce the expression of this receptor in NK and T cells. This gene along with four Other members of the interleukin 1 receptor family, including IL1R2, IL1R1, ILRL2 (IL-1Rrp2), and IL1RL1 (T1/ST2), form a gene cluster on chromosome 2q. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2013]
