The Early Growth Response (EGR) gene family includes EGR1-4 and WT1. These Cys2-His2 zinc finger transcription factors are immediate early genes (IEG) that are rapidly turned on downstream of a number of stimuli and regulate expression of genes involved in stress response and differentiation (reviewed in Pagel and Deindl, 2001; Bahrami and Drabløs, 2016). Roles for EGR proteins are well established in the nervous system, with EGR target genes contributing to synaptic plasticity, long-term potentiation, peripheral nerve myelination and NGF-induced neurite outgrowth (reviewed in Perez-Cadahia et al, 2011; Herdegen and Leah, 1998; O'Donovan et al, 1999).
Expression of EGR genes depends on binding of phosphorylated ternary complex factor (TCF) protein ELK1 and its transcriptional coactivator SRF (serum response factor) to their cognate DNA binding sequences in the promoters (Hooker et al, 2017; De Franco et al, 1993; Harada et al, 2001; reviewed in Herdegen and Leah, 1998). NGF-stimulated expression of EGR1 and 2 occurs downstream of sustained MAPK signaling (Millbrandt et al, 1987; Sukhatme et al, 1988; de Franco et al, 1998; Mullenbrock et al, 2011; Crosby et al, 1991; Lönn et al, 2005). In addition to SRF and TCF binding sites, the EGR1 promoter also contain consensus binding sequences for AP-1 and CREB, as well as binding sites for EGR1 protein itself (Schwachtgen et al, 2000; Thiel et al, 2000; Svaren et al, 1996; reviewed in Page; and Deindl, 2001). Expression of EGR1 is limited by a negative feedback loop mediated by the binding of a complex of EGR1 with a repressor protein of the NAB family (NGF1A binding protein) to the EGR1 binding site (Cao et al, 1990; Thiel et al, 2000; Svaren et al, 1996).
