內皮PAS結構域包含蛋白-1（英語：Endothelial PAS domain-containing protein 1，縮寫EPAS1，也被稱為缺氧誘導因子-2α亞基，英語：Hypoxia-inducible factor-2alpha，縮寫HIF-2α）是一種由人類基因 EPAS1 所編碼的蛋白質^[6]^[7]^[8]^[9]。

功能

EPAS1所表達的蛋白是一個轉錄因子的組成部分，該轉錄因子介導一些受氧氣調控基因的表達，特別是低氧（缺氧）環境下。該蛋白包含一個鹼性螺旋-環-螺旋蛋白二聚化結構域，此結構域也常見於其它氧應激相關信號通路蛋白。EPAS1涉及胚胎心臟（英語：embryonic heart）的發育，並在臍帶的血管壁內皮細胞中表達。EPAS1維持兒茶酚胺類物質在胚胎早期發育中的穩定，以防止心臟衰竭^[9]。兒茶酚胺類物質包括腎上腺素和去甲腎上腺素，其穩定對胎兒與成人的心臟的健康有着重要作用^[10]。

交互作用

EPAS1能與芳香烴受體核轉位子（英語：Aryl hydrocarbon receptor nuclear translocator）^[7]和ARNTL^[11]發生交互作用。
