The BTB/POZ domain of PLZF forms an obligate homodimer with an extensive hydrophobic interface; a surface-exposed groove at the dimer interface is lined with conserved residues suggestive of a corepressor peptide-binding site. The BTB domain directs PLZF to a nuclear punctate pattern and interacts with components of the histone deacetylase complex. |
