ZRT1 protein (Saccharomyces cerevisiae) - STRING interaction network
"ZRT1" - High-affinity zinc transporter of the plasma membrane, responsible for the majority of zinc uptake in Saccharomyces cerevisiae
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology

ZRT1High-affinity zinc transporter of the plasma membrane, responsible for the majority of zinc uptake; transcription is induced under low-zinc conditions by the Zap1p transcription factor; High-affinity zinc transport protein (376 aa)    
Predicted Functional Partners:
Vacuolar membrane zinc transporter, transports zinc from storage in the vacuole to the cytoplasm when needed; transcription is induced under conditions of zinc deficiency; Transports zinc from storage in the vacuole to the cytoplasm (503 aa)
Zinc-regulated transcription factor; binds to zinc-responsive promoters to induce transcription of certain genes in presence of zinc, represses other genes in low zinc; regulates its own transcription; contains seven zinc-finger domains; Involved in zinc ion homeostasis by zinc-responsive transcriptional regulation (880 aa)
Vacuolar membrane zinc transporter, transports zinc from the cytosol into the vacuole for storage; also has a role in resistance to zinc shock resulting from a sudden influx of zinc into the cytoplasm; Probably responsible for the uptake of zinc and cadmium ions (442 aa)
Putative GPI-anchored protein; transcription is induced under low-zinc conditions, as mediated by the Zap1p transcription factor, and at alkaline pH (249 aa)
Low-affinity Fe(II) transporter of the plasma membrane; Required for Fe(2+) ion low affinity uptake (552 aa)
Zinc transporter; localizes to the ER; null mutant is sensitive to calcofluor white, leads to zinc accumulation in cytosol; ortholog of the mouse KE4 and member of the ZIP (ZRT, IRT-like Protein) family; Zinc transporter whose role depends on the zinc status of the cells. It helps to balance zinc levels between the cytosol and the secretory pathway. It transports zinc into the secretory pathway in a zinc-adequate environment and in a high zinc medium. In high zinc medium, transport of zinc into the secretory pathway is a way to eliminate zinc from the cytosol. Under low cytosolic zinc [...] (346 aa)
Member of the cation diffusion facilitator family, localizes to the endoplasmic reticulum and nucleus; mutations affect the cellular distribution of zinc and also confer defects in meiotic recombination between homologous chromatids; Probably act as a zinc ion transporter moving zinc from the nucleus/endoplasmic reticulum to the cytoplasm. Involved in zinc ion homeostasis and cellular distribution (724 aa)
Vacuolar transporter that mediates zinc transport into the vacuole; overexpression confers resistance to cobalt and rhodium; Probably responsible for the uptake of cobalt ions. It appears to act in a dosage-dependent manner to counteract the adverse effects of cobalt ions on cells. It may participate in the regulation of cobalt levels under normal physiological conditions and may be important in the supply of metal that is required for metalloenzyme or cofactor synthesis. It reduces the toxicity of cobalt and rhodium ions. Other components responsible for cobalt transport exist (439 aa)
Ferro-O2-oxidoreductase required for high-affinity iron uptake and involved in mediating resistance to copper ion toxicity, belongs to class of integral membrane multicopper oxidases; Iron transport multicopper ferroxidase required for Fe(2+) ion high affinity uptake. Required to oxidize Fe(2+) and release it from the transporter. Essential component of copper- dependent iron transport (636 aa)
Divalent metal ion transporter; broad specificity for di-valent and tri-valent metals; post-translationally regulated by levels of metal ions; member of the Nramp family of metal transport proteins; High-affinity manganese transporter involved in manganese uptake from the extracellular environment. Contributes also to cellular accumulation of other divalent metal ions such as cadmium, cobalt, copper, iron and nickel (575 aa)
