Zinc transporter 2 (ZnT2) is one of the cellular factors responsible for Zn homeostasis. Upon Zn overload, ZnT2 reduces cellular Zn by transporting it into excretory vesicles. We investigated the molecular mechanism that regulates human ZnT2 (hZnT2) gene expression. Zn induces hZnT2 expression in dose- and time-dependent manners. Overexpression of(More)
Metal-responsive transcription factor 1 (MTF-1) is an essential protein required for mouse embryonic development. We report here the occurrence of sumoylation on MTF-1. Mutational studies demonstrated that sumoylation occurs on the lysine residue at position 627 (Lys(627)) of mouse MTF-1. Small ubiquitin-like modifier (SUMO)-1 was fused to the C terminus of(More)
MTF-1 (metal-responsive transcription factor 1) is an essential mammalian protein for embryonic development and modulates the expression of genes involving in zinc homoeostasis and responding to oxidative stress. We report in the present paper that PTEN (phosphatase and tensin homologue deleted on chromosome 10) associates with MTF-1 in the cells. These two(More)
Metal-responsive transcription factor 1 (MTF-1) regulates a variety of genes involving in metal homeostasis and oxidative stress. We have shown that MTF-1 can be conjugated by small ubiquitin-like modifier (SUMO) and forms complexes with cellular factor(s) in a SUMO-interacting motif (SIM)-dependent manner. To investigate whether the interaction of MTF-1(More)
