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

sir-2.1NAD-dependent protein deacetylase sir-2.1; NAD-dependent deacetylase (By similarity). Required for a reduction of the 'Lys-16' acetylation of histone H4 (H4K16ac) on dosage-compensated X chromosomes in hermaphrodites. Plays a role in germ cell and somatic cell apoptosis in response to DNA damage. Functions upstream of daf-16 in the insulin-like signaling pathway, promoting daf-16 mediated transcriptional activation and increased lifespan. May also regulate lifespan independently of daf-16 by modulating the transcription of genes involved in the stress response of the endoplasmic reticu [...] (607 aa)    
Predicted Functional Partners:
daf-16
Forkhead box protein O; Forkhead-type transcription factor. Binds to the promoters of genes that contain the daf-16 binding element (DBE), TTGTTTAC, in their regulatory region. Functions in the Insulin/IGF-1-like signaling (IIS) mediated pathway which affects lipogenesis, lifespan, starvation survival, heat shock and oxidative stress responses, and dauer formation. Longevity signaling predominantly arises from expression in the intestine. Daf-16 transcriptional activity is negatively regulated by cytoplasmic sequestration by association with ftt-2. Inhibition is required for the carbon [...]

hcf-1
Host cell factor 1.

qns-1
Glutamine-dependent NAD(+) synthetase; In the C-terminal section; belongs to the NAD synthetase family.
  
 
 0.965
nmat-2
Nicotinamide/nicotinic acid mononucleotide adenylyltransferase 2; Catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP. Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate. Belongs to the eukaryotic NMN adenylyltransferase family.
   
 0.944
nmat-1
Nicotinamide-nucleotide adenylyltransferase.
   
 0.944
anmt-1
Nicotinamide N-methyltransferase; Catalyzes the N-methylation of nicotinamide and other pyridines to form pyridinium ions (By similarity). Involved in regulation of lifespan extension downstream of the sirtuin sir-2.1, probably through its role in nicotinic acid metabolism.
     
 0.943
ftt-2
14-3-3-like protein 2; Required for extension of life-span by sir-2.1. Promotes nuclear export of yap-1. Negatively regulates the transcriptional activity of daf-16 by sequestering it to the cytoplasm. Belongs to the 14-3-3 family.
    
 
 0.938
K02D7.1
Purine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.
    
 0.928
aak-2
5'-AMP-activated protein kinase catalytic subunit alpha-2; Acts as a sensor that couples lifespan to information about energy levels and insulin-like signals. Role in motility and response to oxidative stress. Involved in the establishment of germline stem cell (GSC) quiescence during dauer development. Plays a role in axon regrowth after axotomy in PLM neurons. Plays a role in the maintenance of glycogen stores which are necessary for resistance to hyperosmotic stress. Plays a role in the regulation of flp-7 secretion from ASI neurons. Keeps the CREB-regulated transcription coactivato [...]
