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

orai-1Protein orai; Ca(2+) release-activated Ca(2+)-like (CRAC-like) channel subunit which mediates Ca(2+) influx and increase in Ca(2+)-selective current by synergy with the Ca(2+) sensor, stim-1. Required for Ca(2+) and IP3-dependent contractile activity of sheath cells and the spermatheca. Affects brood size and somatic cell function. Belongs to the Orai family. (297 aa)    
Predicted Functional Partners:
stim-1
Stromal interaction molecule 1; Plays a role in mediating store-operated Ca(2+) entry (SOCE), a Ca(2+) influx following depletion of intracellular Ca(2+) stores. Acts as Ca(2+) sensor which upon Ca(2+) depletion, activates the Ca(2+) release-activated Ca(2+) (CRAC) channel subunit, orai-1. Essential for Ca (2+) and IP3-dependent contractile activity of gonad sheath cells and spermatheca. Essential for fertility. Does not play a role in posterior body wall muscle contraction (pBoc) rhythmicity, intestinal cell oscillatory Ca(2+) signaling or intestinal ER Ca(2+) hemostasis.

itr-1
Inositol 1,4,5-trisphosphate receptor itr-1; Receptor for inositol 1,4,5-trisphosphate, a second messenger that regulates intracellular calcium homeostasis. Binds in vitro to both inositol 1,4,5-trisphosphate (1,4,5-InsP3) and inositol 2,4,5-trisphosphate (2,4,5-InsP3) with high affinity and does not discriminate between the phosphate at 1 or 2 position. Can also bind inositol 1,3,4,5-tetrakisphosphate (1,3,4,5-InsP4) and inositol 4,5-bisphosphate (4,5-InsP2), but with lower affinity. Acts as a timekeeper/rhythm generator via calcium signaling, affecting the defecation cycle and pharyn [...]

cmd-1
Calmodulin; Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases.
    
 
 0.653
sca-1
Calcium-transporting ATPase; This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium.
    
 
 0.603
lfe-2
Inositol-trisphosphate 3-kinase homolog; Probably by regulating inositol 1,4,5-trisphosphate levels, negatively regulates posterior body wall muscle contractions required for defecation and let-23 signaling pathway that controls spermathecal dilation and ovulation. May also regulate ovulation downstream of actin cross-linker fln-1.

ccb-2
SH3 domain-containing protein.

egl-19
Voltage-dependent L-type calcium channel subunit alpha; Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death; Belongs to the calcium channel alpha-1 subunit (TC 1.A.1.11) family.
