  • PubMed Abstract: 

    The POZ domain is an evolutionarily conserved protein-protein interaction domain that is found in approximately 40 mammalian transcription factors. POZ domains mediate both homodimerization and the heteromeric interactions of different POZ-domain transcription factors with each other. Miz1 is a POZ-domain transcription factor that regulates cell-cycle arrest and DNA-damage responses. The activities of Miz1 are altered by its interaction with the POZ-domain transcriptional repressors BCL6 and NAC1, and these interactions have been implicated in tumourigenesis in B-cell lymphomas and in ovarian serous carcinomas that overexpress BCL6 and NAC1, respectively. A strategy for the purification of tethered POZ domains that form forced heterodimers is described, and crystal structures of the heterodimeric POZ domains of Miz1/BCL6 and of Miz1/NAC1 are reported. These structures will be relevant for the design of therapeutics that target POZ-domain interaction interfaces.
