The Daxx protein (also known as the Fas-binding protein) is thought to play a role in apoptosis. Daxx forms a complex with Axin. Remodelling of the family to a short domain based on the Structure 2kzs structure gives a more representative family. DAXX is a scaffold protein shown to play diverse roles in transcription and cell cycle regulation. This N-terminal domain folds into a left-handed four-helix bundle (H1, H2, H4, H5) that binds to the N-terminal residues of the tumor-suppressor Rassf1C.
