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

Odc2Ornithine decarboxylase 2; Catalyzes the first and rate-limiting step of polyamine biosynthesis that converts ornithine into putrescine, which is the precursor for the polyamines, spermidine and spermine. Polyamines are essential for cell proliferation and are implicated in cellular processes, ranging from DNA replication to apoptosis. Belongs to the Orn/Lys/Arg decarboxylase class-II family. (393 aa)    
Predicted Functional Partners:
Oda
Ornithine decarboxylase antizyme; Ornithine decarboxylase (ODC) antizyme protein that negatively regulates ODC activity and intracellular polyamine biosynthesis and uptake in response to increased intracellular polyamine levels. Binds to ODC monomers, inhibiting the assembly of the functional ODC homodimer, and targets the monomers for ubiquitin- independent proteolytic destruction by the 26S proteasome (By similarity). Required for cellular differentiation in neuronal and myogenic lineages during embryonic development.
    
 0.996
SpdS
Spermidine synthase activity. It is involved in the biological process described with: polyamine biosynthetic process; spermidine biosynthetic process; Belongs to the spermidine/spermine synthase family.
  
 0.995
arg
Arginase (arg) encodes an enzyme that converts arginine into ornithine. Lack of arg produces a developmental embryonic delay.
  
 
 0.986
SamDC
S-adenosylmethionine decarboxylase (SamDC) encodes a protein involved in defense response to Gram-negative bacterium; Belongs to the eukaryotic AdoMetDC family.
 
  
 
 0.963
Oat
Ornithine aminotransferase, mitochondrial; Ornithine-oxo-acid transaminase activity; identical protein binding; pyridoxal phosphate binding. It is involved in the biological process described with: arginine catabolic process to proline via ornithine; ornithine metabolic process; arginine catabolic process to glutamate.

Odc1
Ornithine decarboxylase 1; Catalyzes the first and rate-limiting step of polyamine biosynthesis that converts ornithine into putrescine, which is the precursor for the polyamines, spermidine and spermine. Polyamines are essential for cell proliferation and are implicated in cellular processes, ranging from DNA replication to apoptosis.

CG8005
Probable deoxyhypusine synthase; Catalyzes the NAD-dependent oxidative cleavage of spermidine and the subsequent transfer of the butylamine moiety of spermidine to the epsilon-amino group of a specific lysine residue of the eIF-5A precursor protein to form the intermediate deoxyhypusine residue.
  
 
 0.771
nero
Deoxyhypusine hydroxylase; Catalyzes the hydroxylation of the N(6)-(4-aminobutyl)-L- lysine intermediate to form hypusine, an essential post-translational modification only found in mature eIF-5A factor (By similarity). Essential for organismal viability and plays a role in a wide number of important processes such as cell growth and proliferation, and regulates induction of autophagy and protein synthesis. Has a role in eIF-5A-mediated translational control; Belongs to the deoxyhypusine hydroxylase family.
  
  
 0.757
P5CS
Delta-1-pyrroline-5-carboxylate synthase; Glutamate-5-semialdehyde dehydrogenase activity; glutamate 5-kinase activity; delta1-pyrroline-5-carboxylate synthetase activity. It is involved in the biological process described with: oxidation-reduction process; proline biosynthetic process; In the C-terminal section; belongs to the gamma-glutamyl phosphate reductase family.
     
 0.725
TyrRS
tRNA binding; tyrosine-tRNA ligase activity; ATP binding. It is involved in the biological process described with: tyrosyl-tRNA aminoacylation.
