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 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

ALDH18A1Delta-1-pyrroline-5-carboxylate synthetase; Delta-1-pyrroline-5-carboxylate synthase; Bifunctional enzyme that converts glutamate to glutamate 5-semialdehyde, an intermediate in the biosynthesis of proline, ornithine and arginine (795 aa)    
Predicted Functional Partners:
OAT
Ornithine aminotransferase, mitochondrial; Ornithine aminotransferase
  
 0.998
ALDH4A1
Delta-1-pyrroline-5-carboxylate dehydrogenase, mitochondrial; Irreversible conversion of delta-1-pyrroline-5- carboxylate (P5C), derived either from proline or ornithine, to glutamate. This is a necessary step in the pathway interconnecting the urea and tricarboxylic acid cycles. The preferred substrate is glutamic gamma-semialdehyde, other substrates include succinic, glutaric and adipic semialdehydes
  
 
 0.992
PYCR1
Pyrroline-5-carboxylate reductase 1, mitochondrial; Housekeeping enzyme that catalyzes the last step in proline biosynthesis. Can utilize both NAD and NADP, but has higher affinity for NAD. Involved in the cellular response to oxidative stress
 
 
 0.987
PYCR2
Pyrroline-5-carboxylate reductase 2; Housekeeping enzyme that catalyzes the last step in proline biosynthesis. In some cell types, such as erythrocytes, its primary function may be the generation of NADP(+). Can utilize both NAD and NADP. Has higher affinity for NADP, but higher catalytic efficiency with NADH. Involved in cellular response to oxidative stress
 
 
 0.974
PYCRL
Pyrroline-5-carboxylate reductase 3; Enzyme that catalyzes the last step in proline biosynthesis. Proline is synthesized from either glutamate or ornithine; both are converted to pyrroline-5-carboxylate (P5C), and then to proline via pyrroline-5-carboxylate reductases (PYCRs). PYCRL is exclusively linked to the conversion of ornithine to proline
 
 
 0.969
GLUD1
Glutamate dehydrogenase 1, mitochondrial; Mitochondrial glutamate dehydrogenase that converts L- glutamate into alpha-ketoglutarate. Plays a key role in glutamine anaplerosis by producing alpha-ketoglutarate, an important intermediate in the tricarboxylic acid cycle. May be involved in learning and memory reactions by increasing the turnover of the excitatory neurotransmitter glutamate (By similarity); Belongs to the Glu/Leu/Phe/Val dehydrogenases family
  
 
 0.966
GLUD2
Glutamate dehydrogenase 2, mitochondrial; Important for recycling the chief excitatory neurotransmitter, glutamate, during neurotransmission; Belongs to the Glu/Leu/Phe/Val dehydrogenases family
  
 
 0.965
GLUL
Glutamate-ammonia ligase; Glutamine synthetase; This enzyme has 2 functions: it catalyzes the production of glutamine and 4-aminobutanoate (gamma-aminobutyric acid, GABA), the latter in a pyridoxal phosphate-independent manner (By similarity). Essential for proliferation of fetal skin fibroblasts; Belongs to the glutamine synthetase family
  
 
 0.960
PRODH
Proline dehydrogenase 1, mitochondrial; Converts proline to delta-1-pyrroline-5-carboxylate; Belongs to the proline oxidase family
  
 
 0.948
POX2
Proline dehydrogenase; Converts proline to delta-1-pyrroline-5-carboxylate; Belongs to the proline oxidase family
  
 
 0.947
