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

skn-1Protein skinhead-1; Transcription factor required to specify the fate of ventral blastomeres in the early embryo, and postembryonically for the development of the intestine. Directly regulates expression of zygotically expressed med-1 and med-2 to direct mesendoderm development. Required for stl-1 mRNA up- regulation in response to oxidative stress and anoxia. Required for the up-regulation of gcs-1 and several glutathione-S-transferase mRNAs in response to oxidative stress generated during pathogenic bacterial infection. In neurons, involved in mitochondrial fusion and behavioral reco [...] (623 aa)    
Predicted Functional Partners:
pmk-1
Mitogen-activated protein kinase pmk-1; Serine/threonine kinase which responds to activation by environmental stress and pro-inflammatory cytokines by phosphorylating downstream targets. Phosphorylates snk-1 which probably regulates skn-1 nuclear translocation in response to oxidative stress. Probably by activating skn-1, involved in the up- regulation of gcs-1 and glutathione-S-transferase gst-4 expression upon bacteria infection. Up-regulates expression of gcs-1 in intestinal cells upon arsenite treatment. Functions downstream of the MAPKK sek-1 and the MAPKKK nsy-1 as the MAP kinase [...]

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 [...]

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 [...]
   
 0.967
pek-1
Eukaryotic translation initiation factor 2-alpha kinase pek-1; Phosphorylates the alpha subunit of eukaryotic translation- initiation factor 2 (eIF2alpha), leading to its inactivation and thus to a rapid reduction of translational initiation and repression of global protein synthesis. May phosphorylate eIF2alpha during hypoxia. Proposed to have a role in alleviating endoplasmic reticulum stress ; Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. GCN2 subfamily.
   
 0.960
wdr-23
DDB1- and CUL4-associated factor 11 homolog; Involved in regulation of lifespan. Required for dopaminergic CEP neuron degeneration in response to Mn(2+).
   
 
 0.953
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.

gst-4
Glutathione S-transferase 4; Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles (By similarity). May play a role in the detoxification of reactive oxygen species produced during pathogenic bacterial infection.
   
  
 0.938
pmk-3
Mitogen-activated protein kinase pmk-3; Responds to activation by environmental stress and pro- inflammatory cytokines by phosphorylating downstream targets. Involved in axon regeneration after injury, probably downstream of dlk-1 and mkk-4 and upstream of mak-2. May phosphorylate mak-2. Plays a role in cilium length regulation, possibly by reducing rab-5 mediated endocytosis. Plays a role in the formation of muscle connections, also called muscle arm extensions, between the body wall and the motor axons in the dorsal and ventral cord.
   
 0.935
pmk-2
Mitogen-activated protein kinase pmk-2; Responds to activation by environmental stress and pro- inflammatory cytokines by phosphorylating downstream targets.
   
 0.927
gsk-3
Glycogen synthase kinase-3; Phosphorylates oma-1, a regulator of the oocyte-to-embryo transition, enabling its degradation. Phosphorylates skn-1, preventing it from accumulating in nuclei and thus inhibiting phase II gene expression in the oxidative stress defense. Involved in mesendoderm specification and mitotic spindle orientation in EMS blastomeres. Thought to be a branch point in these processes as proteins downstream are not required. Negatively regulates Wnt signaling in vulval precursor cells and acts as a Wnt-independent repressor of med-1 and med-2 in the C lineage inhibiting [...]
