| Research Abstract |
Zinc is an essential micronutrient. It is critically important to control intracellular zinc concentrations tightly. In mammals, metallothionein (MT), a small metal-binding protein, plays important roles in zinc homeostasis. Mouse MT-I gene transcription is regulated by metal response element-binding transcription factor-l (MTF-l), which is recruited to the promoter by zinc. Previously we showed that alterations in the chromatin structure of the MT-I promoter associated with enhanced transcriptional activation. Here, we showed that chromatin remodeling factor Brm and Brg1 was not involved in the gene expression.
