Validated All-in-One™ qPCR Primer for IL21R(NM_021798.3) Search again
Powered by BiozBy default, qPCR primer pairs are designed to measure the expression level of the splice variant (accession number) you selected for this gene WITHOUT consideration of other possible variants of this gene. If this gene has multiple variants, and you would like to measure the expression levels of one particular variant, multiple variants, or all variants, please contact us for a custom service project at inquiry@genecopoeia.com.

Each All-in-One™ qPCR Primer is experimentally validated to yield a single dissociation curve peak and to generate a single amplification of the correct size for the targeted gene. A cDNA Pool, containing reverse transcript products of 8 different human tissue total RNA(Liver, Testis,Muscle,Thyroid,Brain,Spleen,Stomach,Small Intestine)),was used as the qPCR validation template. qPCR was performed using 0.2 µM primer with 2XAll-in-One™ qPCR Mix (Catalog#: QP001,QP002,QP004,QP005). Reactions were incubated for 10min. at 95°C, followed by 40 cycles of 95°C for 10 sec.; 60°C, 20 sec. and 72°C, 15sec. using Bio-Rad iQ5™ Instrument. At the end of the last cycle, temperature was increased from 72 to 95°C to produce a melting curve. Panel A: Validated Result for Amplification Curve; Panel B: Validated Result for Melting Curve. |

Summary
The protein encoded by this gene is a cytokine receptor for interleukin 21 (IL21). It belongs to the type I cytokine receptors, and has been shown to form a heterodimeric receptor complex with the common gamma-chain, a receptor subunit also shared by the receptors for interleukin 2, 4, 7, 9, and 15. This receptor transduces the growth promoting signal of IL21, and is important for the proliferation and differentiation of T cells, B cells, and natural killer (NK) cells. The ligand binding of this receptor leads to the activation of multiple downstream signaling molecules, including JAK1, JAK3, STAT1, and STAT3. Knockout studies of a similar gene in mouse suggest a role for this gene in regulating immunoglobulin production. Three alternatively spliced transcript variants encoding the same protein have been described. [provided by RefSeq].
Gene References into function
- IL-21R is associated with the activated phenotype of rheumatoid arthritis synovial fibroblasts independently of the major proinflammatory cytokines IL-1beta and TNFalpha, but not with the destruction of articular cartilage and bone.
- The up-regulation of IL-21R in keratinocytes indicates that its expression pattern is not only altered but it appears to be independent of key cytokines that are operant in systemic scleosis.
- TCR-induced IL-21R expression is driven by TCR-mediated augmentation of Sp1 protein levels and may partly depend on the dephosphorylation of Sp1
- surface IL-21 receptor is expressed at variable levels by chronic lymphocytic leukemia B cells
- IL-21 differentially regulates IL-4-induced IgE production, via its growth- and differentiation-promoting capacities on isotype- committed B cells, & via its ability to induce IFNg production; the outcome depends on the presence of a IL-21R polymorphism.
- IL-21R is overexpressed in the inflamed synovial membrane and in peripheral blood or synovial fluid leukocytes of RA patients. Thus, blockade of IL-21R signalling pathway may have a therapeutic potential in acute RA patients.
- Data suggest a contribution of IL21 and IL21R to genetic susceptibility to type 1 diabetes and possible involvement of IL-21 and its receptor system in the disease pathogenesis.
- Follicular lymphoma cells showed exceptionally high IL-21R expression. IL-21 induced apoptosis in follicular lymphoma cells expressing high levels of IL-21 receptor.
- These results suggest an important role for IL-21R in the mobilization of skin dendritic cells to draining lymph nodes and the subsequent allergic response to epicutaneously introduced antigen.
