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

vab-1Ephrin receptor 1; Receptor for members of the ephrin family (By similarity). Receptor for major sperm proteins (MSPs), that functions as sperm- sensing checkpoint which inhibits oocyte meiotic maturation and ovulation when sperm are not available for fertilization. Specifically, functions to negatively regulates oocyte maturation and MAPK activation in the absence of MSPs. Required for the MSP-mediated increase in the basal sheath cell contraction rate in somatic cells. Phosphorylates phosphatase daf-18/PTEN which probably promotes daf-18 degradation. By inactivating daf-18, regulates [...] (1122 aa)    
Predicted Functional Partners:
vab-2
Ephrin RBD domain-containing protein; Belongs to the ephrin family.
   
 0.993
efn-3
Ephrin RBD domain-containing protein; Belongs to the ephrin family.
   
 0.980
efn-2
Ephrin RBD domain-containing protein; Belongs to the ephrin family.
   
 0.979
efn-4
Ephrin-4; Regulates the formation or stabilization of cell-cell contacts at several stages of epithelial morphogenesis. In early embryonic development, involved in ventral closure of the epidermis. During male tail morphogenesis, regulates precursor cell sorting together with mab-20 and allows the formation of distinct sensory rays. Probably acts as a ligand for lad-2 to regulate axon guidance of several neurons including SDQL, SDQR, SMD and PLN neurons during neurogenesis.
   
 0.973
sax-3
Protein sax-3; Required to confine migrating sex myoblasts to the ventral muscle quadrants during their migration through the body and for multiple aspects of sensory, motor, and interneuron axon guidance. Belongs to the immunoglobulin superfamily. ROBO/SAX3 family.
   
 
 0.922
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, [...]

vpr-1
Major sperm protein; Central component in molecular interactions underlying sperm crawling. Forms an extensive filament system that extends from sperm villipoda, along the leading edge of the pseudopod.
   
 
 0.898
unc-6
Netrin unc-6; Component of an extracellular matrix cue that guides dorsoventral migrations on the epidermis. Required for the guidance of pioneer axons and migrating cells along the body wall. During gonad morphogenesis, involved in distal tip cell (DTC) migration from the dorsal side of the hermaphrodite body to the midbody to allow for formation of gonad arms. Its association with either unc-40 or unc-5 receptors will lead to axon attraction or repulsion, respectively. Involved in the positioning of ray 1, the most anterior ray sensilium, in the male tail. Required for the formation [...]

dab-1
PID domain-containing protein.
   
 
 0.804
mab-20
Semaphorin-2A; Regulates the formation or stabilization of cell-cell contacts at several stages of epithelial morphogenesis. In early embryonic development, required for proper ventral closure of the epidermis. During male tail morphogenesis, regulates precursor cell sorting and allows the formation of distinct sensory rays. Seems to control cell-cell contact formation through 2 parallel pathways, one involving efn-4 and one involving plx-2 and unc-129. Involved in axon guidance. Probably by binding receptor plx-2, regulates fln-1-mediated remodeling of the actin cytoskeleton and thus [...]
