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

lin-3Protein lin-3; Probable ligand for tyrosine kinase receptor let-23. Essential for vulval induction, where it acts downstream of the synthetic multivulva (synMuv) class genes. Probably by activating let-23, phospholipase plc-3 and inositol 1,4,5-trisphosphate receptor itr-1 signaling cascade, plays a role in ovulation by promoting gonadal sheath cell contractions and spermatheca dilatation during ovulation. Probably by regulating neuronal transmission in ALA neurons, mediates the decrease in pharyngeal pumping and locomotion during the quiescent state that precedes each larval molt, by [...] (477 aa)    
Predicted Functional Partners:
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 [...]

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.
   
 
 0.914
lin-12
Protein lin-12; Involved in several cell fate decisions that require cell- cell interactions. It is possible that lin-12 encodes a membrane-bound receptor for a signal that enables expression of the ventral uterine precursor cell fate. Activity in cell fate decisions and tumorigenesis is negatively regulated by sel-10. Functions in uterine cells to promote basement membrane mobility during tissue remodeling.

mpk-1
Mitogen-activated protein kinase mpk-1; Function in let-60 Ras signaling pathway; acts downstream of lin-45 raf kinase, but before the lin-1 gene product in controlling vulval cell differentiation. Plays a negative role in proximal germline proliferation in the mitotic zone. Required for progression of developing oocytes through the pachytene stage. In oocytes, inhibits the activity of the chloride channel clh-3, likely by activating gck-3. Plays a role in response to M.nematophilum-mediated bacterial infection by promoting tail swelling and preventing constipation. Involved in fluid h [...]

lin-45
Raf homolog serine/threonine-protein kinase; Protein kinase that participates in the induction of vulva and has roles in fertility and viability. Acts downstream of the Ras protein let-60. Required for progression of developing oocytes through the pachytene stage. Plays a role in responses to M.nematophilum- mediated bacterial infection by promoting tail swelling and preventing constipation. Positively regulates lifespan upstream of mek-2 and mpk-1. Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. RAF subfamily.

egl-17
EGL-17; Belongs to the heparin-binding growth factors family.
      
 0.850
sem-5
Sex muscle abnormal protein 5; Adapter protein which modulates signaling mediated by several receptor tyrosine kinases such as egl-15 and let-23 probably acting upstream of let-60/ras. Negatively regulates vulva induction probably downstream of let-23. Involved in sex myoblast migration. Negatively regulates fluid homeostasis probably downstream of egl-15. During the formation of neuromuscular junctions at the larval stage, negatively regulates membrane protrusion from body wall muscles probably downstream of egl- 15. Involved in cytoskeleton dynamics and is recruited by mig-13 to the [...]

lin-2
Protein lin-2; May play a structural role in the induction of the vulva. May be required for the localization of signal transduction molecules (such as let-23 receptor) to either the basal membrane domain or the cell junctions.
      
 0.807
lin-31
Protein lin-31; Lin-31 regulates how vulval precursor cells choose their fate. It helps specify three alternative cell fates in vulval development.

plc-3
1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase gamma plc-3; Mediates the production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) which plays an important role in the regulation of intracellular signaling cascades (Probable). Regulates basal and ovulatory sheath cell contractions by controlling Ca(2+) oscillations via IP3-mediated activation of IP3 receptor itr-1. In intestinal epithelial cells, regulates Ca(2+) oscillations which control posterior body wall muscle contractions required for defecation by IP3-mediated activation [...]
