功能

EPAS1所表达的蛋白是一个转录因子的组成部分，该转录因子介导一些受氧气调控基因的表达，特别是低氧（缺氧）环境下。该蛋白包含一个碱性螺旋-环-螺旋蛋白二聚化结构域，此结构域也常见于其它氧应激相关信号通路蛋白。EPAS1涉及胚胎心脏（英语：embryonic heart）的发育，并在脐带的血管壁内皮细胞中表达。EPAS1维持儿茶酚胺类物质在胚胎早期发育中的稳定，以防止心脏衰竭^[9]。儿茶酚胺类物质包括肾上腺素和去甲肾上腺素，其稳定对胎儿与成人的心脏的健康有着重要作用^[10]。

交互作用

EPAS1能与芳香烃受体核转位子（英语：Aryl hydrocarbon receptor nuclear translocator）^[7]和ARNTL^[11]发生交互作用。
