Active Recombinant Rat Interleukin 4, HIgG1 Fc-tagged

• Cat.No.: IL4-458R
• Product Overview: The extracellular domain of rat IL-4(NP_000580)(Met1-Ser153) is fused to the N-terminus of the Fc region of human IgG1 was expressed in CHO cell.

Specification

• Description: The protein encoded by this gene is a pleiotropic cytokine produced by activated T cells. This cytokine is aligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to manyoverlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, hasbeen 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 anover 120 kilobase range on the chromosome. Two alternatively spliced transcript variants of this gene encodingdistinct isoforms have been reported.
