MIZ zinc finger
In molecular biology the MIZ-type zinc finger domain is a zinc finger-containing protein with homology to the yeast protein, Nfi-1. Miz1 is a sequence specific DNA binding protein that can function as a positive-acting transcription factor. Miz1 binds to the homeobox protein Msx2, enhancing the specific DNA-binding ability of Msx2. Other proteins containing this domain include the human pias family (protein inhibitor of activated STAT protein). The name MIZ is derived from Msx-interacting-zinc finger. The crystal structure of S. cerevisiae sumo e3 ligase siz1 containing this domain has been solved. References
