Oct4

Module:Infobox_gene第53行Lua错误：attempt to index field 'wikibase' (a nil value)

Oct4（八聚体结合转录因子4, octamer-binding transcription factor 4）,亦称为POU5F1（第五类POU结构域转录因子1），化学式为：C₁₇₁₈H₂₆₅₇O₅₁₇N₄₆₉S₁₃^[1]，是一种蛋白质，在人体中由POU5F1基因编码^[2]。Oct4是一种具有与POU结构域（英语：POU domain）同源的结构域的转录因子。Oct4对未分化的胚胎干细胞的自我更新与干性维持至关重要^[3]。也正因如此，有时Oct4会被用来作标记未分化细胞的分子标记。Oct4的过表达或低表达都会造成细胞的分化，因此Oct4只在特定的表达强度下才能维持细胞的干性^[4]。

Oct4（八聚体结合转录因子4）名称中的“八聚体”（octamer）指DNA核苷酸序列“A TTTG CAT”^[5]。
