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

itr-1Inositol 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 [...] (2892 aa)    
Predicted Functional Partners:
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 [...]

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.

egl-8
1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase beta egl-8; 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 (By similarity). Required in the nervous system to modulate neuronal activity. Facilitates synaptic transmission at neuromuscular junctions by regulating the release of acetylcholine from the motor neurons and thus affecting locomotion. Plays a role in efficient egg laying and defecation. Involved in axon regeneration [...]

plc-4
Phosphoinositide phospholipase C.

bec-1
Beclin homolog; Regulates autophagy. Together with phosphatidyl-3-phosphate kinase vps-34, acts as a core subunit of the PI3K complex that mediates formation of phosphatidylinositol 3- phosphate (PtdIns3P), thereby regulating membrane trafficking. In association with sorf-1 and sorf-2, negatively regulates phosphatidylinositol 3- phosphate in early endosomes to allow for the conversion to late endosomes. Involved in the clearance of engulfed apoptotic cell corpses. Together with ced-9, negatively regulates somatic and germline apoptosis. Plays a role in endosome-to-Golgi retrograde tra [...]

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.

plc-1
1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase epsilon-1; The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes. plc-1 is a bifunctional enzyme which also regulates small GTPases of the Ras superfamily through its Ras guanine-exchange factor (RasGEF) activity (By similarity). By activating IP3 receptor itr-1-mediated intracellular Ca(2+) release via the production of IP3, regulates ovulation by controlling contraction and/or dilation of the di [...]

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.

orai-1
Protein 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.
