该基因编码一个转录调控因子，属于c2h2型锌指蛋白的egr家族。它是一种由有丝分裂刺激诱导的即刻早期生长反应基因。由该基因编码的蛋白质参与了控制生物节律的基因转录调控。它还可能在多种过程中发挥作用，包括肌肉发育、淋巴细胞发育、内皮细胞生长和迁移以及神经元发育选择性剪接导致编码不同亚型的多个转录变体。[由RefSeq提供，2010年12月]
This gene encodes a transcriptional regulator that belongs to the EGR family of C2H2-type zinc-finger proteins. It is an immediate-early growth response gene which is induced by mitogenic stimulation. The protein encoded by this gene participates in the transcriptional regulation of genes in controling biological rhythm. It may also play a role in a wide variety of processes including muscle development, lymphocyte development, endothelial cell growth and migration, and neuronal development. Alternative splicing results in multiple transcript variants encoding distinct isoforms.[provided by RefSeq, Dec 2010]
