Protein

Hepatocyte nuclear factor 4-alpha

Gene

Hnf4a

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Transcriptionally controlled transcription factor. Binds to DNA sites required for the transcription of alpha 1-antitrypsin, apolipoprotein CIII, transthyretin genes and HNF1-alpha. May be essential for development of the liver, kidney and intestine.

Miscellaneous

DNA-binding activity of phosphorylated protein is reduced by fasting and by inducers of intracellular cyclic AMP.
Binds fatty acids.

Post-translational modificationi

Phosphorylation at Ser-313 by AMPK reduces the ability to form homodimers and bind DNA (By similarity). Phosphorylated in the recognition sequence R-R-S-S near the DNA-binding domain; phosphorylation results in decrease in DNA-binding activity. Phosphorylation of HNF4 depends on the diet and is decreased by a carbohydrate-rich diet and is increased by fasting.By similarity1 Publication
The N-terminus is blocked.
Acetylation at Lys-458 lowers transcriptional activation by about two-fold.By similarity
