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:
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

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; HAD Asp-based non-protein phosphatases (225 aa)    
Predicted Functional Partners:
PSAT1
Phosphoserine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily
  
 
 0.996
SHMT2
Serine hydroxymethyltransferase, mitochondrial; Contributes to the de novo mitochondrial thymidylate biosynthesis pathway via its role in glycine and tetrahydrofolate metabolism. Thymidylate biosynthesis is required to prevent uracil accumulation in mtDNA. Interconversion of serine and glycine. Associates with mitochondrial DNA. Plays a role in the deubiquitination of target proteins as component of the BRISC complex. Required for IFNAR1 deubiquitination by the BRISC complex; Belongs to the SHMT family
  
 0.984
SHMT1
Serine hydroxymethyltransferase, cytosolic; Interconversion of serine and glycine
  
 0.983
SDS
L-serine dehydratase/L-threonine deaminase; Serine dehydratase
  
 
 0.956
AGXT
Alanine-glyoxylate aminotransferase
  
 0.952
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. Also catalyzes the reversible oxidation of 2-hydroxyglutarate to 2-oxoglutarate and the reversible oxidation of (S)-malate to oxaloacetate; Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family
  
 
 0.949
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
  
 
 0.938
SDSL
Serine dehydratase-like; Has low serine dehydratase and threonine dehydratase activity
  
 
 0.934
CBSL
Cystathionine beta-synthase-like protein; 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. Also involved in the production of hydrogen sulfide, a gasotransmitter with signaling and cytoprotective effects on neurons
   
 
 0.931
PPM1K
Protein phosphatase 1K, mitochondrial; Regulates the mitochondrial permeability transition pore and is essential for cellular survival and development; Belongs to the PP2C family
      
 0.904
