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

Sirt2NAD-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. (355 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.
  
 0.963
Nadsyn
Glutamine-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.
    
 0.946
CG33156
Uncharacterized protein, isoform E; NAD+ kinase activity. It is involved in the biological process described with: NAD metabolic process; NADP biosynthetic process.
  
 
 0.922
foxo
Forkhead box protein O; Transcription factor involved in the regulation of the insulin signaling pathway. Consistently activates both the downstream target Thord4EBP and the feedback control target InR. Involved in negative regulation of the cell cycle, modulating cell growth and proliferation. In response to cellular stresses, such as nutrient deprivation or increased levels of reactive oxygen species, foxo is activated and inhibits growth through the action of target genes such as Thor. Foxo activated in the adult fat body can regulate lifespan in adults; an insulin peptide itself m [...]

CG18128
FI08065p; Purine-nucleoside phosphorylase activity. It is involved in the biological process described with: nucleoside metabolic process.
    
 0.917
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.
     
  0.900
HDAC6
Histone deacetylase 6, isoform G; Histone deacetylase 6 (HDAC6) encodes a cytosolic deacetylase that functions as a key modulator of proteostasis by mediating ubiquitin-proteasomal and lysosomal degradation of native and/or misfolded proteins.
    
 
 0.897
HDAC1
Histone deacetylase HDAC1; Catalyzes the deacetylation of lysine residues on the N- terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation may constitute a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. For instance, deacetylation of histone H3 may be a prerequisite for the subsequent recruitment of the histone methyltransferase Su(var)3-9 to histones. Involved in position-effect variegation (PEV). In the larval brain, part of a regulatory network including the transcript [...]
    
 
 0.811
Ankle2
Ankyrin repeat and LEM domain containing 2, isoform D; Ankle2 (Ankle2) encodes an important protein for proper development of the third instar larval CNS. Ankle2 loss causes a small brain phenotype, defects in proliferation and excessive apoptosis.
    
 0.782
HDAC11
Histone deacetylase activity.
