Reversible Activation of Mouse Metal Response Element-Binding Transcription Factor 1 DNA Binding Involves Zinc Interaction with the Zinc Finger Domain
1 May 1997
Abstract excerpt
The DNA-binding activity of the Zn finger protein metal response element-binding transcription factor 1 (MTF-1) was rapidly induced both in vivo in mouse Hepa cells, canine MDCK, and human HeLa cells after incubation in medium containing zinc and in vitro in whole-cell extracts to which zinc was added. Acquisition of DNA-binding capacity in the presence of free zinc was temperature and time dependent and did not...
