Target Information
Interleukin-4 (IL-4) is a pleiotropic immune-modulatory cytokine produced by activated T cells and serves as a ligand for the IL-4 receptor. It has broad biological functions and shares overlapping roles with IL-13. STAT6 acts as a key mediator in IL-4 signaling.
The IL-4 gene, along with IL-3, IL-5, IL-13, and CSF2, forms a cytokine gene cluster on chromosome 5q. IL-4 and IL-13 are closely located and regulated by long-range elements over a 120 kb region. IL-4 delta 2 is a known splice variant.
