Application

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.

Biochem/physiol Actions

The nerve growth factor-induced clone C (NGFI-C/EGR4) gene is a zinc-finger transcription factor that is rapidly induced by nerve growth factor in rat 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 NFAT 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.

General description

Early growth response (Egr) proteins are transcriptional regulators (Egr1-4) of gene expression involved in the growth and differentiation of many cells. Early growth response 4 (EGR4, NGFI-C, pAT133), a member of the Egr family of zinc-finger transcription factors, regulates early stage meiosis and functions as a master gene transcription regulator of processes such as spermatogenesis and male fertility. Egr4 is an important component in the mechanism for trophic factor-mediated upregulation of K-Cl cotransporter (KCC2) in immature neurons.
