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

vpr-1Major 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. (245 aa)    
Predicted Functional Partners:
vab-1
Ephrin 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 [...]

obr-1
Oxysterol-binding protein; Belongs to the OSBP family.
    
 
 0.801
tdp-1
Tar DNA-binding protein homolog 1; RNA-binding protein which regulates transcription, splicing and RNA-editing. Limits the accumulation of double- stranded RNA by maintaining the abundance of the mature RNA transcripts that are formed from double-stranded precursor RNAs. Stress response protein that acts downstream of daf-16 in the insulin/IGF pathway to regulate longevity and the cellular stress response to osmotic, oxidative, proteotoxic and endoplasmic reticulum stress. Involved in the regulation of physiological processes including aging, fertility, growth and locomotion.

tag-232
Phosphofurin Acidic Cluster Sorting protein homolog.

clr-1
Receptor-type tyrosine-protein phosphatase; Possesses an intrinsic protein tyrosine phosphatase (PTPase) activity. Regulates egl-15 activity which is required for hypodermis-mediated fluid homeostasis and protein degradation in muscle. During the formation of neuromuscular junctions at the larval stage, negatively regulates membrane protrusion from body wall muscles. Plays a role in nicotinic acetylcholine receptor (nAChR)-mediated sensitivity to nicotine. Regulates synaptic levels of nAchR subunit lev-1 in the nerve cord. Promotes the outgrowth of the quaternary dendritic branches of [...]
