STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SAM3High-affinity S-adenosylmethionine permease; required for utilization of S-adenosylmethionine as a sulfur source; has similarity to S-methylmethionine permease Mmp1p. (587 aa)    
Predicted Functional Partners:
SAM4
Homocysteine S-methyltransferase 2; S-adenosylmethionine-homocysteine methyltransferase; functions along with Mht1p in the conversion of S-adenosylmethionine (AdoMet) to methionine to control the methionine/AdoMet ratio; SAM4 has a paralog, YMR321C, that arose from a single-locus duplication.
   
  
 0.846
DUR3
Plasma membrane transporter for both urea and polyamines; expression is highly sensitive to nitrogen catabolite repression and induced by allophanate, the last intermediate of the allantoin degradative pathway; Belongs to the sodium:solute symporter (SSF) (TC 2.A.21) family.
   
  
 0.775
SAM1
S-adenosylmethionine synthase 1; S-adenosylmethionine synthetase; catalyzes transfer of the adenosyl group of ATP to the sulfur atom of methionine; SAM1 has a paralog, SAM2, that arose from the whole genome duplication.
   
  
 0.727
SAM2
S-adenosylmethionine synthase 2; S-adenosylmethionine synthetase; catalyzes transfer of the adenosyl group of ATP to the sulfur atom of methionine; comparative analysis suggests that a mitochondrially targeted form may result from translation starting at a non-canonical codon upstream of the annotated start codon.
   
  
 0.714
MHT1
Homocysteine S-methyltransferase 1; S-methylmethionine-homocysteine methyltransferase; functions along with Sam4p in the conversion of S-adenosylmethionine (AdoMet) to methionine to control the methionine/AdoMet ratio.
   
  
 0.656
TPO1
Polyamine transporter of the major facilitator superfamily; member of the 12-spanner drug:H(+) antiporter DHA1 family; recognizes spermine, putrescine, and spermidine; catalyzes uptake of polyamines at alkaline pH and excretion at acidic pH; during oxidative stress exports spermine, spermidine from the cell, which controls timing of expression of stress-responsive genes; phosphorylation enhances activity and sorting to the plasma membrane; Belongs to the major facilitator superfamily. DHA1 family. Polyamines/proton antiporter (TC 2.A.1.2.16) subfamily.
   
 
 0.612
MUP1
High affinity methionine permease; integral membrane protein with 13 putative membrane-spanning regions; also involved in cysteine uptake; To yeast low affinity methionine permease (MUP3).
   
 
 0.611
YHR214W-A
Putative uncharacterized protein YHR214W-A; Dubious open reading frame; induced by zinc deficiency; YHR214W-A has a paralog, YAR068W, that arose from a segmental duplication.
      
 0.597
MUP3
Low affinity methionine permease; similar to Mup1p.
   
 
 0.572
TPO5
Polyamine transporter TPO5; Protein involved in excretion of putrescine and spermidine; putative polyamine transporter in the Golgi or post-Golgi vesicles; Belongs to the amino acid-polyamine-organocation (APC) superfamily.
      
 0.539
