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

daf-16Forkhead 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 [...] (541 aa)    
Predicted Functional Partners:
akt-1
Serine/threonine-protein kinase akt-1; Acts downstream of PI3 kinase age-1 and kinase pdk-1 in the daf-2/insulin receptor-like transduction pathway. Phosphorylates Forkhead-related daf-16 and the longevity-promoting skn-1 transcription factors, which inhibits their entry into the nucleus and antagonizes their functions. Has an essential role in regulating developmental arrest at the dauer stage. Plays a role in immune function and pathogen resistance. Regulates salt chemotaxis learning. Downstream of age-1 and together with akt-2 and sgk-1, promotes cell survival during embryonic devel [...]

akt-2
Serine/threonine-protein kinase akt-2; Acts downstream of PI3 kinase age-1 and kinase pdk-1 in the daf-2/insulin receptor-like transduction pathway. Essential role in regulating developmental arrest at the dauer stage. Phosphorylates Forkhead-related daf- 16 and the longevity-promoting skn-1 transcription factors, which inhibits their entry into the nucleus and antagonizes their functions. Role in immune function and pathogen resistance. Downstream of age-1 and together with akt-2 and sgk-1, promotes cell survival during embryonic development. Belongs to the protein kinase superfamily.

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 [...]

daf-2
Insulin-like receptor subunit alpha; Insulin receptor-like tyrosine kinase which regulates metabolism, controls longevity and prevents developmental arrest at the dauer stage. Binding of INS family members may either stimulate, or antagonize, association of the receptor with downstream mediators such as pdk-1 and age-1. Required for germline progenitor proliferation during larval development. Required for the response to environmental stimuli such as food, pheromone, and temperature. Negatively regulates resistance to UV and oxidative stress. Role in immune function and pathogen resist [...]

sgk-1
Serine/threonine-protein kinase sgk-1; Acts downstream of PI3 kinase age-1 and kinase pdk-1 in the daf-2/insulin receptor-like transduction pathway. Essential role in regulating development, stress response, and longevity. Phosphorylates Forkhead- related daf-16 and the longevity-promoting skn-1 transcription factors, which inhibits their entry into the nucleus and antagonizes their function. Acts downstream of rict-1 to regulate fat storage, size, and development. Downstream of age-1 and together with akt-1/2, promotes cell survival during embryonic development. Does not appear to pla [...]

daf-18
Abnormal dauer formation protein 18; Acts as a dual-specificity protein phosphatase, dephosphorylating tyrosine-, serine- and threonine-phosphorylated proteins (By similarity). Also acts as a lipid phosphatase, removing the phosphate in the D3 position of the inositol ring from phosphatidylinositol 3,4,5-trisphosphate. By dephosphorylating PtdIns(3,4,5)P3 antagonizes PtdIns(3,4,5)P3 production by age-1/PI3K and thus, negatively regulates daf-2-mediated processes including dauer formation, longevity, fat metabolism, chemotaxis towards salt, thermotolerance and axon guidance. Similarly, [...]

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 [...]

age-1
Phosphatidylinositol 3-kinase age-1; Phosphatidylinositol 3-kinase homolog that regulates longevity and diapause. Promotes cell survival during embryonic development by recruiting akt-1/2 to the plasma membrane through the production of PtdIns(3,4,5)P3. Could function in the development or neuroendocrine signaling of the dauer pathway. Mediates susceptibility to enteropathogenic E.coli infection. May negatively regulate AYI interneuron neurite outgrowth. Plays a role in aversive olfactory learning when an odor is associated with food deprivation.
