Cation Diffusion Facilitator family: Structure and function.
The Cation Diffusion Facilitators (CDFs) form a family of membrane-bound proteins capable of transporting zinc and other heavy metal ions. Involved in metal tolerance/resistance by efflux of ions, CDF proteins share a two-modular architecture consisting of a transmembrane domain (TMD) and C-terminal domain (CTD) that protrudes into the cytoplasm. Discovery of a Zn²⁺ and Cd²⁺ CDF transporter fro...
متن کاملGenes encoding proteins of the cation diffusion facilitator family that confer manganese tolerance.
The yeast Saccharomyces cerevisiae expressing a cDNA library prepared from Stylosanthes hamata was screened for enhanced Mn(2+) tolerance. From this screen, we identified four related cDNAs that encode membrane-bound proteins of the cation diffusion facilitator (CDF) family. One of these cDNAs (ShMTP1) was investigated in detail and found to confer Mn(2+) tolerance to yeast by internal sequestr...
متن کاملZinc ions and cation diffusion facilitator proteins regulate Ras-mediated signaling.
C. elegans cdf-1 was identified in a genetic screen for regulators of Ras-mediated signaling. CDF-1 is a cation diffusion facilitator protein that is structurally and functionally similar to vertebrate ZnT-1. These proteins have an evolutionarily conserved function as positive regulators of the Ras pathway, and the Ras pathway has an evolutionarily conserved ability to respond to CDF proteins. ...
متن کاملThe chromosomally encoded cation diffusion facilitator proteins DmeF and FieF from Wautersia metallidurans CH34 are transporters of broad metal specificity.
Genomic sequencing of the beta-proteobacterium Wautersia (previously Ralstonia) metallidurans CH34 revealed the presence of three genes encoding proteins of the cation diffusion facilitator (CDF) family. One, CzcD, was previously found to be part of the high-level metal resistance system Czc that mediates the efflux of Co(II), Zn(II), and Cd(II) ions catalyzed by the CzcCBA cation-proton antipo...
متن کاملThe cation diffusion facilitator gene cdf-2 mediates zinc metabolism in Caenorhabditis elegans.
Zinc is essential for many cellular processes. To use Caenorhabditis elegans to study zinc metabolism, we developed culture conditions allowing full control of dietary zinc and methods to measure zinc content of animals. Dietary zinc dramatically affected growth and zinc content; wild-type worms survived from 7 microm to 1.3 mm dietary zinc, and zinc content varied 27-fold. We investigated cdf-...
