Due to their immutable nature, metals are a group of pollutants of much concern. As a result
of human activities such as mining and smelting of metalliferous ores, electroplating, gas …

▪ Abstract New insights into mammalian zinc metabolism have been acquired through the
identification and characterization of zinc transporters. These proteins all have …

Arabidopsis thaliana has eight genes encoding members of the type 1B heavy metal–
transporting subfamily of the P-type ATPases. Three of these transporters, HMA2, HMA3 …

SLC30A8, a novel member of the zinc transporter (ZnT) family, was identified by searching
the human genomic and expressed sequence tag (EST) databases with the amino acid …

The hyperaccumulation of zinc (Zn) and cadmium (Cd) is a constitutive property of the
metallophyte Arabidopsis halleri. We therefore used Arabidopsis GeneChips to identify …

In recent years, a number of mammalian zinc transporters have been identified, and
candidate genes are rapidly growing. These transporters are classified into two families: ZIP …

SLC39 proteins are members of the broader ZIP family of metal ion transporters found in
organisms at all phylogenetic levels. Most ZIP transporters have eight predicted …

Cation diffusion facilitator (CDF) proteins belong to a family of heavy metal efflux
transporters that might play an essential role in homeostasis and tolerance to metal ions. We …

Vacuolar compartmentalization or cell wall binding in leaves could play a major role in
hyperaccumulation of heavy metals. However, little is known about the physiology of …

PIB-type ATPases transport heavy metal ions (Cu+, Cu2+, Zn2+, Cd2+, Co2+, etc.) across
biological membranes. Several members of this subfamily are present in plants. Higher …
