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

ras-1GTP binding protein. (212 aa)    
Predicted Functional Partners:
sos-1
Son of sevenless homolog; Promotes the exchange of Ras-bound GDP by GTP (By similarity). May regulate signaling pathways downstream of receptor tyrosine kinase, egl-15 and let-23. Required for larval and male spicule development, fluid homeostasis, vulva induction, spermatogenesis, and oogenesis by promoting meiosis prophase exit during oocyte maturation. Required for the delamination of G1 cell by promoting the loss of cell junctions and detachment from the excretory system during larval development. Plays a role in nicotinic acetylcholine receptor (nAChR)-mediated sensitivity to nico [...]
   
 0.967
pxf-1
Rap guanine nucleotide exchange factor; Acts as a guanine nucleotide exchange factor for small G protein GTPases like rap-1 and rap-2. Required in the hypodermis, especially in the seam cells, for proper formation of the cuticle. Belongs to the RAPGEF2 family.
   
 0.927
ras-2
GTP binding protein.
  
 
0.914
let-60
Ras protein let-60; The level of let-60 controls the switch between vulval and hypodermal cell fates during C.elegans vulval induction. May stimulate the guanine nucleotide exchange factor (GEF) activity of rap-1. Belongs to the small GTPase superfamily. Ras family.
  
 
0.908
shn-1
Protein shank; Scaffold protein that most likely acts in the postsynaptic density (PSD) of excitatory synapses which orchestrates synapse formation and maintenance at neuromuscular junctions. Associates with and trafficks the L-type calcium channel egl-19 to the cell surface of body wall muscles to ensure the function of the calcium channel and therefore maintain the Ca(2+) current density. The maintenance of Ca(2+) also allows for the downstream regulation of Ca(2+)-induced expression of genes such as gem-4. Plays a role in the regulation of the defecation cycle, and this may be in as [...]
  
 
 0.878
ksr-1
Kinase suppressor of Ras A; Serine/threonine-protein kinase which positively regulates Ras-mediated signaling probably acting at the level of let-60/ras or/and lin-45/raf. Involved in sex myoblast migration. Plays a role in responses to M.nematophilum-mediated bacterial infection by promoting tail swelling and preventing constipation. Functions redundantly with ksr-2 in the Ras-mediated regulation of larval survival, the development of excretory canal and in mpk-1 phosphorylation in somatic cells. In addition, involved in determining vulval precursor cell fate during vulval induction i [...]
   
 
 0.733
let-23
Receptor tyrosine-protein kinase let-23; Tyrosine-protein kinase receptor which, upon binding ligand lin-3, activates 2 signaling cascades: the let-60/Ras and MAP kinase signaling pathway and the let-60-independent phospholipase C-mediated Ca(2+) signaling pathway. Each pathway regulates distinct functions. By activating let-60/Ras, regulates larval development, induction of vulva cell precursors during vulva development, male spicule formation and posterior development of the epidermis. Probably by activating phospholipase plc-3 and inositol 1,4,5-trisphosphate receptor itr-1 signalin [...]
   
 
 0.698
kin-1
cAMP-dependent protein kinase catalytic subunit; Essential for larval development. Controls the rhythmic contraction of enteric muscles probably by regulating G- protein coupled receptor aex-2-mediated calcium influx in GABAergic DVB neurons. Plays a role in the control of oocyte meiotic maturation by gonadal sheath cells. Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. cAMP subfamily.
   
 
 0.661
unc-89
Muscle M-line assembly protein unc-89; Structural component of the muscle M line which is involved in assembly and organization of sarcomere myofilaments. The large isoform a, isoform b, isoform d and isoform f play an essential role in maintaining the organization of sarcomeres but not myofilament alignment during body wall muscle development whereas the small isoform c and isoform d appear to have a minor role. Isoform b and isoform f are required for the organization of unc-15/paramyosin into sarcomere thick filaments in body wall muscles. By binding mel-26, a substrate adapter of t [...]
   
 
 0.634
plx-2
Plexin-2; Involved as a receptor for mab-20/sema-2a in 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, involved in precursor cell sorting and in the formation of distinct sensory rays. Involved in axon guidance of SDQL neurons during neurogenesis. Probably in response to stimulation by mab-20, regulates fln-1-mediated remodeling of the actin cytoskeleton and thus axon guidance and/or fasciculation of DD/VD neurons. Bel [...]
