IL1R1 (interleukin 1 receptor, type I), also known as CD121a, is a single-pass, type I transmembrane glycoprotein that belongs to the interleukin 1 receptor (IL1R) family. The IL1R family comprises at least 10 members, which typically contain 3 immunoglobulin (Ig)-like domains in the extracellular region. Most members also have an intracellular TIR (Toll-like receptor/IL-1 receptor) signaling domain that is also conserved in the Toll-like receptor family. There are two distinct types of receptors for the pleiotropic cytokines IL1α and IL1β: the type I (IL1R1) is an 80 kDa transmembrane protein expressed predominantly in T cells, fibroblasts, and endothelial cells and mediates all the known IL-1 biological functions while the type II (IL1R2) is a 68 kDa transmembrane protein with a short cytoplamic domain and serves as a decoy receptor for IL1. Both receptors are members of the immunoglobulin superfamily (IgSF). However the two receptors do not heterodimerize into a receptor complex. IL1R1 acts as a receptor for both IL-1α and IL-1β through the association with the co-receptor IL1RAP (interleukin 1 receptor antagonist protein). IL1R1 and IL1RAP together form a high affinity IL-1 receptor complex, which mediates IL-1-dependent activation of NF-κB, MAPK and other signaling pathways. IL-1R1 signaling involves the recruitment of adapter molecules, such as MYD88 and IRAK1/IRAK2, via the respective TIR domains. IL1R1 is an important mediator involved in many cytokine induced immune and inflammatory responses. Recombinant soluble form of IL1R1 has been shown to be a potent antagonist of IL1 action.
Gene Symbol: IL1R1; CD121a; P80; IL1R; IL1RA; IL1RT1; D2S1473; IL-1R-α; IL-1R-1; IL-1RT-1; IL-1R1
NCBI Gene ID: 3554
Uniprot Entry: P14778
Construct Details: Full length human IL1R1 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter -/+ an antibiotic selection marker, which can be used for both transient and stable expression in mammalian cells. It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles.
Vector Type: pLTC or pLTC-Marker (see the vector map above)
Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)
Gene Insert Size: 1710 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:
(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;
(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’
Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification. High fidelity PCR systems should always be used.
