Summary: | The protein encoded by this gene is a pleiotropic cytokine produced by activated T cells. This cytokine is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. This gene, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. This gene, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome. IL4 is considered an important cytokine for tissue repair, counterbalancing the effects of proinflammatory type 1 cytokines, however, it also promotes allergic airway inflammation. Moreover, IL-4, a type 2 cytokine, mediates and regulates a variety of human host responses such as allergic, anti-parasitic, wound healing, and acute inflammation. This cytokine has been reported to promote resolution of neutrophil-mediated acute lung injury. In an allergic response, IL-4 has an essential role in the production of allergen-specific immunoglobin (Ig) E. This pro-inflammatory cytokine has been observed to be increased in COVID-19 (Coronavirus disease 2019) patients, but is not necessarily associated with severe COVID-19 pathology. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. [provided by RefSeq, Aug 2020]. |
Order a complex pool of 30 siRNAs (siPOOL) for the specific gene knockdown of human gene IL4.
siPOOLs (siRNA pools) are high complexity pools of 30 optimally selected siRNAs designed to specifically knock-down the target gene of your choice.
Using 30 siRNAs at a picomolar concentration dilutes and significantly minimizes the off-target effects of each siRNA, therefore highly increasing the on-target specificity. On the other hand, individual siRNAs or low complexity siRNA pools containing only 2-4 siRNAs often display dominant off-target profiles and exhibit variable target gene knock-downs.
As reaction numbers depend on transfection efficiencies and well/plate format used, please refer to our FAQ section or siPOOL transfection protocol for more information.
