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

Sirt6Sirtuin 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. (325 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.

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.

CG33156
Uncharacterized protein, isoform E; NAD+ kinase activity. It is involved in the biological process described with: NAD metabolic process; NADP biosynthetic process.
  
 
 0.918
CG18128
FI08065p; Purine-nucleoside phosphorylase activity. It is involved in the biological process described with: nucleoside metabolic process.
    
 0.909
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
Sirt4
NAD-dependent protein deacylase Sirt4; NAD-dependent protein deacylase. Catalyzes the NAD-dependent hydrolysis of acyl groups from lysine residues.

His3:CG31613
Histone H3; Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.

His3.3A
Histone H3.3A; Variant histone H3 which replaces conventional H3 in a wide range of nucleosomes in active genes and is specifically enriched in modifications associated with active chromatin. Constitutes the predominant form of histone H3 in non-dividing cells and is incorporated into chromatin independently of DNA synthesis. Deposited at sites of nucleosomal displacement throughout transcribed genes, suggesting that it represents an epigenetic imprint of transcriptionally active chromatin. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular mach [...]

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.
