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

pmk-1Mitogen-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 [...] (377 aa)    
Predicted Functional Partners:
skn-1
Protein 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 [...]

vhp-1
Tyrosine-protein phosphatase vhp-1; Acts preferentially on the c-Jun N-terminal kinase (JNK) and p38 MAPKs. Plays an important role in the heavy metal stress response and in axon regeneration by negatively regulating the kgb-1 (JNK-like) and the pmk-1 (p38-type) MAPK signaling pathways. Belongs to the protein-tyrosine phosphatase family. Non- receptor class dual specificity subfamily.
   
 0.992
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 [...]

mak-2
MAP kinase-activated protein kinase mak-2; Serine/threonine-protein kinase which is involved in maintaining synapse and axon morphology as well as touch neuron axon regeneration after injury by regulating cebp-1 mRNA stability downstream of the dlk-1, mkk-4 and pmk-3 signaling cascade. May play a role in body wall muscle contraction. 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.
  
0.987
sek-1
Dual specificity mitogen-activated protein kinase kinase sek-1; Dual specificity protein kinase which acts as an essential component of the p38 signal transduction pathway which is also composed of upstream effector nsy-1 and downstream effector pmk-1. May phosphorylate pmk-1. Downstream of CaMKII unc-43 and adapter protein tir- 1, plays a role in determining asymmetric cell fates in olfactory AWC neurons during neuronal development. Activation results in the repression of odorant receptor str-2 expression in one of the 2 AWC neurons. Involved in resistance to pathogenic Gram-positive [...]

atf-7
BZIP domain-containing protein.

tir-1
NAD(+) hydrolase tir-1; NAD(+) hydrolase, which plays a key role in non-apoptotic cell death by regulating NAD(+) metabolism. In response to stress, homooligomerizes and catalyzes cleavage of NAD(+) into ADP-D-ribose (ADPR) and nicotinamide; NAD(+) cleavage promoting non-apoptotic neuronal cell death. In males, involved in non-apoptotic death of the linker cell which guides gonad elongation during larval development. Required for both innate immune response and specification of AWC(OFF) neuron. During late embryogenesis, it. acts downstream of CAMKII (unc-43) to regulate specification [...]

mek-1
Dual specificity mitogen-activated protein kinase kinase mek-1; Dual specificity protein kinase which may phosphorylate kgb-1 and thereby is an essential component of the JNK pathway composed of mlk-1, mek-1 and kgb-1. May also have a synergistic role with sek-1 in phosphorylating pmk-1. Involved in the response to environmental stress including heavy metal ions (Cu(2+) and Cd(2+)), oxidative stress and starvation. In association with sek-1, regulates germline cell apoptosis in response to oxidative, osmotic and heat shock stresses. Involved in resistance to pathogenic bacteria infecti [...]

lip-1
Dual specificity protein phosphatase lip-1; Dephosphorylates MAP kinase mpk-1. Belongs to the protein-tyrosine phosphatase family. Non- receptor class dual specificity subfamily.

rskn-2
Putative ribosomal protein S6 kinase alpha-2; Serine/threonine kinase that may play a role in mediating the mitogen- and stress-induced effects on transcription. May repress transcription via phosphorylation of 'Ser-1' of histone H2A. May phosphorylate histone H3 (By similarity).
