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

PsphPhosphoserine phosphatase; Catalyzes the last step in the biosynthesis of serine from carbohydrates. The reaction mechanism proceeds via the formation of a phosphoryl-enzyme intermediates (By similarity); Belongs to the HAD-like hydrolase superfamily. SerB family. (225 aa)    
Predicted Functional Partners:
Psat1
Phosphoserine aminotransferase.
  
 
 0.999
Shmt2
Serine hydroxymethyltransferase; Interconversion of serine and glycine. Belongs to the SHMT family.
  
 0.994
Shmt1
Serine hydroxymethyltransferase; Interconversion of serine and glycine. Belongs to the SHMT family.
  
 0.993
Agxt
Serine--pyruvate aminotransferase, mitochondrial; Dual metabolic roles of gluconeogenesis (in the mitochondria) and glyoxylate detoxification (in the peroxisomes).
   
 0.989
Cbs
Cystathionine beta-synthase; Hydro-lyase catalyzing the first step of the transsulfuration pathway, where the hydroxyl group of L-serine is displaced by L- homocysteine in a beta-replacement reaction to form L-cystathionine, the precursor of L-cysteine. This catabolic route allows the elimination of L-methionine and the toxic metabolite L-homocysteine (By similarity). Also involved in the production of hydrogen sulfide, a gasotransmitter with signaling and cytoprotective effects on neurons.
  
 
 0.966
Phgdh
D-3-phosphoglycerate dehydrogenase; Catalyzes the reversible oxidation of 3-phospho-D-glycerate to 3-phosphonooxypyruvate, the first step of the phosphorylated L- serine biosynthesis pathway. Does not catalyze the reversible oxidation of 2-hydroxyglutarate to 2-oxoglutarate and the reversible oxidation of (S)-malate to oxaloacetate.
  
 0.964
Srr
Serine racemase; Catalyzes the synthesis of D-serine from L-serine. D-serine is a key coagonist with glutamate at NMDA receptors. Has dehydratase activity towards both L-serine and D-serine.
    
 0.949
Sdsl
Serine dehydratase-like (Predicted).
    
 0.927
LOC688286
Similar to threonine aldolase 1.
    
 0.849
Gart
Trifunctional purine biosynthetic protein adenosine-3; In the C-terminal section; belongs to the GART family. In the central section; belongs to the AIR synthase family.
