STRINGSTRING
MMT1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MMT1" - Putative metal transporter involved in mitochondrial iron accumulation in Saccharomyces cerevisiae
Nodes:
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:
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
Others
textmining
co-expression
protein homology

MMT1Putative metal transporter involved in mitochondrial iron accumulation; closely related to Mmt2p; Mitochondrial metal transporter involved in mitochondrial iron accumulation (510 aa)    
Predicted Functional Partners:
PEX5
Peroxisomal membrane signal receptor for the C-terminal tripeptide signal sequence (PTS1) of peroxisomal matrix proteins, required for peroxisomal matrix protein import; also proposed to have PTS1-receptor independent functions; Binds to the C-terminal PTS1-type tripeptide peroxisomal targeting signal (SKL-type) and plays an essential role in peroxisomal protein import (612 aa)
       
      0.868
MRS3
Iron transporter that mediates Fe2+ transport across the inner mitochondrial membrane; mitochondrial carrier family member, similar to and functionally redundant with Mrs4p; active under low-iron conditions; may transport other cations; MRS3 suppresses a mitochondrial splice defect in the first intron of the COB gene. It may act as a carrier, exerting its suppressor activity via modulation of solute concentrations in the mitochondrion (possibly of cations) (314 aa)
           
  0.697
SOD1
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)
       
 
  0.678
MSC2
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)
   
   
  0.642
MRS4
Iron transporter that mediates Fe2+ transport across the inner mitochondrial membrane; mitochondrial carrier family member, similar to and functionally redundant with Mrs3p; active under low-iron conditions; may transport other cations; MRS4 suppresses a mitochondrial splice defect in the first intron of the COB gene. It may act as a carrier, exerting its suppressor activity via modulation of solute concentrations in the mitochondrion (possibly of cations). Not essential (304 aa)
           
  0.626
ERG25
C-4 methyl sterol oxidase, catalyzes the first of three steps required to remove two C-4 methyl groups from an intermediate in ergosterol biosynthesis; mutants accumulate the sterol intermediate 4,4-dimethylzymosterol; Catalyzes the first step in the removal of the two C-4 methyl groups of 4,4-dimethylzymosterol (309 aa)
       
 
  0.604
SMF3
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)
     
 
  0.597
COT1
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)
   
   
  0.572
YFH1
Mitochondrial matrix iron chaperone; oxidizes and stores iron; interacts with Isu1p to promote Fe-S cluster assembly; mutation results in multiple Fe/S-dependent enzyme deficiencies; human frataxin homolog is mutated in Friedrich’s ataxia; Promotes the biosynthesis of heme as well as the assembly and repair of iron-sulfur clusters by delivering Fe(2+) to proteins involved in these pathways. Plays a role in the protection against iron-catalyzed oxidative stress through its ability to catalyze the oxidation of Fe(2+) to Fe(3+). Can store large amounts of the metal in the form of a ferrih [...] (174 aa)
           
  0.548
CCC1
Putative vacuolar Fe2+/Mn2+ transporter; suppresses respiratory deficit of yfh1 mutants, which lack the ortholog of mammalian frataxin, by preventing mitochondrial iron accumulation; Has a role in both calcium and manganese homeostasis. Involved in the transfer of iron and Mn(2+) from the cytosol to the vacuole for storage of these metals (322 aa)
