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

hif-1Hypoxia-inducible factor 1; A transcription factor which is a key regulator in various cellular processes; including environment stress resistance (oxygen levels, hydrogen sulfide and cyanide levels and heat), negative regulation of cell apoptosis in ASJ neurons by inhibition of cep-1 via transcriptional activation of tyr-2, resistance/susceptibility to pathogenic bacteria, lifespan and brood size. Involved in mediating susceptibility to enteropathogenic E.coli. Increased levels of hif-1 activity confer resistance to P.aeruginosa-mediated death but also confer susceptibility to S.aureu [...] (721 aa)    
Predicted Functional Partners:
aha-1
Aryl hydrocarbon receptor nuclear translocator homolog; Has a role in cellular differentiation. Required for pharyngeal development. In collaboration with ahr-1 it is involved in RMEL/R and SDQR neuron cell migration. Acts in the cellular response to hypoxia. Involved in aggregation behavior by regulating soluble guanylate cyclase gene expression in the URX neurons.

vhl-1
Von Hippel-Lindau tumor suppressor homolog; Involved in the response to variation in environmental oxygen levels by targeting the hypoxia-inducible transcription factor hif-1 for proteasomal degradation when oxygen levels are normal (around 20%). By regulating hif-1 expression, plays a role in iron homeostasis, aging, heat acclimation and progeny size. Mediates resistance to enteropathogenic E.coli. Mediates susceptibility to B.thuringiensis pore-forming toxins. Not involved in P.aeruginosa susceptibility. Belongs to the VHL family.

egl-9
Hypoxia-inducible factor prolyl hydroxylase; Cellular oxygen sensor which regulates the stability and the activity of hypoxia-inducible transcription factor, hif-1. In normoxic conditions, hydroxylates hif-1 targeting it for vhl-1-mediated proteasomal degradation. In addition, regulates hif-1 transcriptional activity in a vhl-1-independent manner and independently of its hydroxylase activity. By regulating hif-1 activity, controls several cellular responses. Mediates susceptibility to B.thuringiensis and V.cholerae pore-forming toxins and enteropathogenic E.coli. Mediates susceptibilit [...]

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 [...]

F07A11.4
Ubiquitin carboxyl-terminal hydrolase.

cul-2
Cullin-2; Core component of multiple cullin-RING-based CBC (Cul2- ElonginB-ElonginC) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. As a scaffold protein may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. The functional specificity of the CBC complex depends on the variable substrate recognition component (By similarity). May function in ubiquitin-mediated degradation of CKIs to target cki-1 for degradation. CBC(zif-1) may ensure germline precursor cell [...]

hsp-90
Heat shock protein 90; Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co- chaperones that modulate its substrate recognition, ATPase cycle and chaperone function. By stabilizing the receptor-type guanylate cyclase daf-11 or another sig [...]

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 [...]
