Anti-EGR4 polyclonal antibody is used to tag early growth response 4 proteins for detection and quantitation by Western blotting and in cells and tissues by immunohistochemical (IHC) techniques. It is used as a probe to study the role of early growth response 4 protein in spermatogenesis and male fertility.
The nerve growth factor-induced clone C (NGFI-C/EGR4) gene is a zinc-finger transcription factor th at is rapidly induced by nerve growth factor in r at pheochromocytoma PC12 cells and by seizure in brain. NGFI-C/EGR4 is closely related to the previously described early response genes, nerve growth factor-induced clone A (NGFI-A or EGR1), EGR2, and EGR3. These four early response (immediate early) proteins all contain very similar zinc-finger DNA binding domains and five highly homologous subdomains. EGR-4 functionally cooperate with NF at proteins and induce expression of IL-2 and TNFalpha. Early growth response proteins (EGR) and nuclear factors of activated T cells (NFAT) form heterodimers and regulate proinflammatory cytokine gene expression.
