Forkhead box protein A2

Molecular classification
Transcription factor, Forkhead family protein, Pioneer transcription factor
01

Overview

FOXA2 is a transcription factor that plays a crucial role in embryonic development, tissue-specific gene expression, and the regulation of gene networks essential for organogenesis and cell differentiation. It functions as a pioneer transcription factor by binding to condensed chromatin, displacing histones, and promoting chromatin accessibility for other factors. FOXA2 is involved in glucose homeostasis, anti-oxidant responses, and cell type specification. Aberrant activity has been linked to hepatocellular carcinoma and drug resistance.

Other names
Hepatocyte nuclear factor 3-betaHNF-3B
02

Mechanism of action

As a pioneer factor, FOXA2 binds nucleosome-bound DNA, displaces histones to open chromatin, and facilitates recruitment of other regulatory proteins.
