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

Sirt1NAD-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. (823 aa)    
Predicted Functional Partners:
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 [...]

srl
Spargel, isoform B; Transcription coregulator activity; mRNA binding; nuclear receptor transcription coactivator activity; transcription factor binding; nucleic acid binding.

Sirt7
NAD-dependent protein deacetylase Sirt7; NAD-dependent protein deacetylase.

Clk
Circadian locomoter output cycles protein kaput; Circadian regulator that acts as a transcription factor and generates a rhythmic output with a period of about 24 hours. Oscillates in antiphase to the cycling observed for period (PER) and timeless (TIM). According to reaches peak abundance within several hours of the dark-light transition at ZT0 (zeitgeber 0), whereas describes bimodal oscillating expression with maximum at ZT5 and ZT23. Clock-cycle heterodimers activate cycling transcription of PER and TIM by binding to the E-box (5'-CACGTG-3') present in their promoters. Once induced [...]

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.
   
 0.988
Atg5
Autophagy protein 5; Involved in autophagic vesicle formation. Conjugation with Atg12, through a ubiquitin-like conjugating system involving Atg7 as an E1-like activating enzyme and Atg10 as an E2-like conjugating enzyme, is essential for its function. The Atg12-Atg5 conjugate acts as an E3- like enzyme which is required for lipidation of Atg8 and its association to the vesicle membranes (By similarity).

Atg7
Autophagy-related 7 (Atg7) encodes an E1-type ligase for the autophagic ubiquitin-like proteins encoded by Atg8a and Atg12. Its roles include autophagosome formation, maintaining neuromuscular function and normal lifespan.
   
 
 0.985
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 [...]

Atg8a
Autophagy-related 8a (Atg8a) encodes a ubiquitin-like protein that is conjugated to phosphatidylethanolamine, and this lipid modification anchors it into the membrane of forming and completed autophagosomes. Atg8a product has roles in autophagosome formation, maintaining neuromuscular function and normal lifespan.

cyc
Protein cycle; Putative transcription factor involved in the generation of biological rhythms. Activates cycling transcription of Period (PER) and Timeless (TIM) by binding to the E-box (5'-CACGTG-3') present in their promoters.
