該基因編碼一個轉錄因子的紅細胞轉化特異性（ETS）家族成員。這個家族的所有成員都是胚胎發育、細胞增殖、分化、血管生成、炎癥和凋亡的關鍵調節者。該基因編碼的蛋白質主要在細胞核內表達。包含一個ets-dna結合域和一個與嵌合癌蛋白的自結合有關的pnt（尖）域。這種蛋白是血小板粘附在內皮下，誘導血管細胞重塑所必需的。它還調節造血和巨核細胞的分化和成熟。該基因參與染色體易位，產生不同的融合基因產物，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。已經報道了由三個替代啟動子的組合使用和多個替代剪接事件產生的二十多個轉錄變體，但許多這些變體的全長性質尚未確定。
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.
