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

Predicted Functional Partners:
ogt-1
UDP-N-acetylglucosamine--peptide N-acetylglucosaminyltransferase; Addition of nucleotide-activated sugars directly onto the polypeptide through O-glycosidic linkage with the hydroxyl of serine or threonine.

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 [...]

sir-2.1
NAD-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 [...]

ash-2
Set1/Ash2 histone methyltransferase complex subunit ash-2; Component of the set-2/ash-2 histone methyltransferase (HMT) complex (Probable). Required for the di- and trimethylation at 'Lys-4' of histone H3, a mark associated with epigenetic transcriptional activation. Implicated in the epigenetic inheritance of lifespan over several generations. Functions as transcriptional regulator. Acts in the germline to limit the longevity of the soma, probably by regulating a lipid metabolism pathway that signals from the germline to the intestine, thereby preventing accumulation of mono-unsaturat [...]

rbbp-5
Retinoblastoma-binding protein homolog 5; Required for di- and trimethylation at 'Lys-4' of histone H3.
   
 
 0.906
wdr-5.1
WD repeat-containing protein wdr-5.1; Contributes to histone modification. May position the N-terminus of histone H3 for efficient trimethylation at 'Lys-4'. Required for di- and trimethylation, particularly for the trimethylation at 'Lys-4' of histone H3. Not required for demethylation of histone H3 'Lys-27'. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation, germline establishment, maintenance and function. Implicated in the epigenetic inheritance of lifespan over several generations. Acts in the germline to limit the longevity of the soma, pr [...]
   
 
 0.867
set-2
Histone-lysine N-methyltransferase set-2; Histone methyltransferase that specifically di- and trimethylates 'Lys-4' of histone H3 at all developmental stages and in adult germ cells. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation. Implicated in the epigenetic inheritance of lifespan over several generations. Acts in the germline to limit the longevity of the soma, probably by regulating a lipid metabolism pathway that signals from the germline to the intestine, thereby preventing accumulation of mono-unsaturated fatty acids. Methylation in th [...]

dpy-30
Dosage compensation protein dpy-30; Essential for dosage compensation. Required for the sex-specific association of the dosage compensation complex proteins dpy-27 and dpy-26 with the hermaphrodite X chromosomes. Plays a role in developmental rate and body fat regulation downstream of the TOR complex 2. Required for the robust transdifferentiation of the Y rectal cell to the PDA motor neuron during larval development.
   
 
 0.863
set-1
Histone-lysine N-methyltransferase set-1; Histone methyltransferase that specifically monomethylates 'Lys-20' of histone H4 (H4K20me1). H4K20me1 is enriched on hermaphrodite X chromosomes and during mitosis. Involved in dosage compensation by repression of X-linked gene expression in hermaphrodites. Plays a role in growth and body fat regulation downstream of the TOR complex 2 pathway. Belongs to the class V-like SAM-binding methyltransferase superfamily. Histone-lysine methyltransferase family. PR/SET subfamily.
