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

NadsynGlutamine-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source (By similarity). Because of its role in energy metabolism, involved in the modulation of aged- related cardiac function, mobility, and lifespan. (787 aa)    
Predicted Functional Partners:
Nmnat
Nicotinamide mononucleotide adenylyltransferase (Nmnat) encodes an essential enzyme in the NAD salvage pathway, catalyzing the last step of NAD synthesis. It is also a neuronal maintenance factor that protects neurons from excitotoxicity, environmental stress and protein misfolding induced degeneration.
  
 
 0.986
Naprt
Nicotinate phosphoribosyltransferase; Catalyzes the first step in the biosynthesis of NAD from nicotinic acid, the ATP-dependent synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate. Helps prevent cellular oxidative stress via its role in NAD biosynthesis; Belongs to the NAPRTase family.
  
  
 0.984
Sirt1
NAD-dependent histone deacetylase sirtuin-1; NAD-dependent histone deacetylase involved in heterochromatic silencing. Mildly suppresses the heterochromatin-mediated silencing phenomenon known as position-effect variegation (PEV). Required for epigenetic silencing of the polycomb group proteins. Has histone H4 deacetylase activity in vitro. Required maternally for establishing proper segmentation of the embryo. Involved in sex determination. May be involved in the regulation of life span.
  
 
 0.961
CG33156
Uncharacterized protein, isoform E; NAD+ kinase activity. It is involved in the biological process described with: NAD metabolic process; NADP biosynthetic process.
  
 
 0.954
CG8080
NAD kinase 2, mitochondrial; Mitochondrial NAD(+) kinase that phosphorylates NAD(+) to yield NADP(+). Can use both ATP or inorganic polyphosphate as the phosphoryl donor.
     
 0.948
Sirt2
NAD-dependent protein deacetylase Sirt2; NAD-dependent protein deacetylase (By similarity). May be involved in the regulation of life span; Belongs to the sirtuin family. Class I subfamily.
    
 0.946
Sirt4
NAD-dependent protein deacylase Sirt4; NAD-dependent protein deacylase. Catalyzes the NAD-dependent hydrolysis of acyl groups from lysine residues.
    
 0.945
Sirt6
Sirtuin 6 (Sirt6) encodes an NAD-dependent histone deacetylase in the class IV of the Sirtuin family. It is involved in chromatin silencing and determination of adult lifespan.
  
 
 0.941
Sirt7
NAD-dependent protein deacetylase Sirt7; NAD-dependent protein deacetylase.
  
 
 0.938
bur
Burgundy, isoform B; Burgundy (bur) encodes a GMP synthetase required for axon guidance. It regulates the activity of the ubiquitin protease encoded by Usp7.
