Function

[ZBT17_HUMAN] Plays a critical role in early lymphocyte development, where it is essential to prevent apoptosis in lymphoid precursors, allowing them to survive in response to IL7 and undergo proper lineage commitment (By similarity). Transcription factor that can function as an activator or repressor depending on its binding partners, and by targeting negative regulators of cell cycle progression. Has been shown to bind to the promoters of adenovirus major late protein and cyclin D1 and activate transcription. Required for early embryonic development during gastrulation.^[1] ^[2] ^[3]

Publication Abstract from PubMed

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.
