Egr-1 is an early growth response gene that displays fos-like induction kinetics in fibroblasts, epithelial cells, and lymphocytes following mitogenic stimulation. Sequence analysis of murine Egr-1 cDNA predicts a protein with three DNA binding zinc fingers. The human EGR1 gene maps to chromosome 5 (bands 5q23-31). Egr-1 mRNA increases dramatically during cardiac and neural cell differentiation, and following membrane depolarization both in vitro and in vivo. Thus, Egr-1 and c-fos are often coregulated with strikingly similar kinetics. These results, in conjunction with the Egr-1 primary structure, suggest that Egr-1 may function as a transcriptional regulator in diverse biological processes.
Egr-1是一种早期生长反应基因,在有丝分裂原刺激后,成纤维细胞、上皮细胞和淋巴细胞中呈现出类似Fos的诱导动力学。对小鼠Egr-1 cDNA的序列分析预测其编码一种具有三个DNA结合锌指的蛋白质。人类EGR1基因定位于5号染色体(5q23 - 31带)。在心脏和神经细胞分化过程中,以及在体内外膜去极化后,Egr-1 mRNA会显著增加。因此,Egr-1和c-fos常常以极为相似的动力学共同被调节。这些结果,连同Egr-1的一级结构,表明Egr-1可能在多种生物学过程中作为转录调节因子发挥作用。
