该基因编码一个转录因子的红细胞转化特异性（ETS）家族成员。这个家族的所有成员都是胚胎发育、细胞增殖、分化、血管生成、炎症和凋亡的关键调节者。该基因编码的蛋白质主要在细胞核内表达。包含一个ets-dna结合域和一个与嵌合癌蛋白的自结合有关的pnt（尖）域。这种蛋白是血小板粘附在内皮下，诱导血管细胞重塑所必需的。它还调节造血和巨核细胞的分化和成熟。该基因参与染色体易位，产生不同的融合基因产物，如前列腺癌的tmpssr2-erg和ndrg1-erg，尤因肉瘤的ews-erg和急性髓性白血病的fus-erg。已经报道了由三个替代启动子的组合使用和多个替代剪接事件产生的二十多个转录变体，但许多这些变体的全长性质尚未确定。
This gene encodes a member of the erythroblast transformation-specific (ETS) family of transcriptions factors. All members of this family are key regulators of embryonic development, cell proliferation, differentiation, angiogenesis, inflammation, and apoptosis. The protein encoded by this gene is mainly expressed in the nucleus. It contains an ETS DNA-binding domain and a PNT (pointed) domain which is implicated in the self-association of chimeric oncoproteins. This protein is required for platelet adhesion to the subendothelium, inducing vascular cell remodeling. It also regulates hematopoesis, and the differentiation and maturation of megakaryocytic cells. This gene is involved in chromosomal translocations, resulting in different fusion gene products, such as TMPSSR2-ERG and NDRG1-ERG in prostate cancer, EWS-ERG in Ewing's sarcoma and FUS-ERG in acute myeloid leukemia. More than two dozens of transcript variants generated from combinatorial usage of three alternative promoters and multiple alternative splicing events have been reported, but the full-length nature of many of these variants has not been determined.
