Solution Structure of Miz-1 Zinc Finger 13
Structural highlights
FunctionZBT17_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 PubMedMiz-1 is a BTB/POZ transcription factor that contains 13C2H2 Zinc Finger domains (ZF). Miz-1 transactivates and represses the transcription of a myriad of genes involved in many aspects of the biology of the cell. The detailed molecular interactions through which Miz-1 controls transcription, including its specific DNA binding via its ZF domains, remain to be understood and documented. In our effort to shed light into the structural biology of Miz-1, we have undertaken the determination of the structure of all its ZF and the characterization of their interactions with cognate DNA. The structure of ZF 1 to 10 have already been solved and characterized. Here, we present the structure of the synthetic Miz-1 ZF13 determined by 2D (1)H-(1)H NMR.
