Octamer-binding Transcription Factor 4 (OCT4)

Target
OCT4
Molecular classification
Transcription factor, POU family homeodomain transcription factor
01

Overview

Octamer-binding transcription factor 4 (OCT4), encoded by the *POU5F1* gene, is a homeodomain transcription factor crucial for maintaining pluripotency and self-renewal of embryonic stem cells. It regulates gene expression by binding to octamer DNA motifs and is implicated in various cancers, where its overexpression promotes tumor proliferation, metastasis, and chemoresistance. OCT4 is a potential therapeutic target for anti-cancer strategies, especially those targeting cancer stem-like cells.
