ATX2 protein (Saccharomyces cerevisiae) - STRING interaction network
"ATX2" - Golgi membrane protein involved in manganese homeostasis 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

ATX2Golgi membrane protein involved in manganese homeostasis; overproduction suppresses the sod1 (copper, zinc superoxide dismutase) null mutation; Functions in the homeostasis of manganese ions (313 aa)    
Predicted Functional Partners:
Cytosolic copper-zinc superoxide dismutase; some mutations are analogous to those that cause ALS (amyotrophic lateral sclerosis) in humans; Destroys radicals which are normally produced within the cells and which are toxic to biological systems (154 aa)
Heavy metal ion homeostasis protein, facilitates trafficking of Smf1p and Smf2p metal transporters to the vacuole where they are degraded, controls metal ion transport, prevents metal hyperaccumulation, functions in copper detoxification; Required for homeostasis of heavy metal ions such as cadmium, cobalt and copper. Controls metal ion transport and prevents metal hyperaccumulation by negatively regulating the SMF1 and SMF2 metal transport systems. Under manganese-replete conditions facilitates trafficking of SMF1 and SMF2 metal transporters to the vacuole where they are degraded (321 aa)
Cytosolic copper metallochaperone that transports copper to the secretory vesicle copper transporter Ccc2p for eventual insertion into Fet3p, which is a multicopper oxidase required for high-affinity iron uptake; Shuttles copper to the transport ATPase CCC2. Protects against oxygen toxicity (73 aa)
High affinity Ca2+/Mn2+ P-type ATPase required for Ca2+ and Mn2+ transport into Golgi; involved in Ca2+ dependent protein sorting and processing; mutations in human homolog ATP2C1 cause acantholytic skin condition Hailey-Hailey disease; This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium. Has a role in the secretory pathway (950 aa)
Transketolase, similar to Tkl2p; catalyzes conversion of xylulose-5-phosphate and ribose-5-phosphate to sedoheptulose-7-phosphate and glyceraldehyde-3-phosphate in the pentose phosphate pathway; needed for synthesis of aromatic amino acids; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate (680 aa)
Conserved protein of the mitochondrial matrix, performs a scaffolding function during assembly of iron-sulfur clusters, interacts physically and functionally with yeast frataxin (Yfh1p); isu1 isu2 double mutant is inviable; Scaffold protein for the de novo synthesis of iron- sulfur (Fe-S) clusters within mitochondria, which is required for maturation of both mitochondrial and cytoplasmic [2Fe-2S] and [4Fe-4S] proteins. First, a [2Fe-2S] cluster is transiently assembled on the scaffold proteins ISU1 and ISU2. In a second step, the cluster is released from ISU1/ISU2, transferred to gluta [...] (165 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)
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)
Putative divalent metal ion transporter involved in iron homeostasis; transcriptionally regulated by metal ions; member of the Nramp family of metal transport proteins; Has a role in controlling the cellular iron ion levels. Mobilizes vacuolar stores of iron in conditions of low iron levels (473 aa)
