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

csp-3Non-catalytic caspase homolog csp-3; Non-catalytic caspase homolog which does not contain the region necessary for caspase activity. Acts as an inhibitor of caspase ced-3 zymogen autoactivation and delays ced-4- induced ced-3 processing. Has no effect on active ced-3. Probably by preventing ced-3 activation, protects cells, whose fate is to live, from apoptosis during embryonic and larval development ; Belongs to the peptidase C14A family. (139 aa)    
Predicted Functional Partners:
ced-4
Cell death protein 4; Component of the egl-1, ced-9, ced-4 and ced-3 apoptotic signaling cascade required for the initiation of programmed cell death in cells fated to die during embryonic and postembryonic development. During oogenesis, required for germline apoptosis downstream of ced-9 and upstream of ced-3 but independently of egl-1. May regulate germline apoptosis in response to DNA damage, probably downstream of let-60/ras and mpk-1 pathway. Regulates CEP neuron apoptosis in response to high Al(3+) levels. During male tail morphogenesis, promotes apoptosis of the tail-spike cell [...]

ced-9
Apoptosis regulator ced-9; Plays a major role in programmed cell death (PCD, apoptosis). egl-1 binds to and directly inhibits the activity of ced-9, releasing the cell death activator ced-4 from a ced-9/ced-4 containing protein complex and allowing ced-4 to activate the cell-killing caspase ced-3. During larval development, required for the elimination of transient presynaptic components downstream of egl-1 and upstream of ced-4 and ced-3 apoptotic pathway.
   
 
 0.806
ced-3
Cell death protein 3 subunit p13; Acts as a cysteine protease in controlling programmed cell death (apoptosis) by proteolytically activating or inactivating a wide range of substrates. Component of the egl-1, ced-9, ced-4 and ced-3 apoptotic signaling cascade required for the initiation of programmed cell death in cells fated to die during embryonic and postembryonic development. During oogenesis, required for germline apoptosis downstream of ced-9 and ced-4 but independently of egl-1. By cleaving and activating ced-8, promotes phosphatidylserine exposure on the surface of apoptotic ce [...]

K11D12.9
RING-type domain-containing protein.
   
 
 0.745
egl-1
Programmed cell death activator egl-1; Plays a major role in programmed cell death (PCD or apoptosis) by negatively regulating ced-9. Binds to and directly inhibits the activity of ced-9, releasing the cell death activator ced-4 from a ced- 9/ced-4 containing protein complex and allowing ced-4 to activate the cell-killing caspase ced-3. Required to activate programmed cell death in the sister cells of the serotonergic neurosecretory motor (NSM) neurons during embryogenesis. Required to activate programmed cell death in the sister cells of the M4 motor neuron and I1 pharyngeal neuron du [...]
      
 0.667
ced-6
Cell death protein 6; May function as an adapter protein in a pathway that mediates recognition and phagocytosis of apoptotic cells during normal development. Promotes engulfment of cells at both early and late stages of apoptosis. Required for actin reorganization around apoptotic cells. Belongs to the ced-6 family.
      
 0.618
bir-2
Baculoviral IAP repeat-containing protein bir-2.
   
 
 0.590
bir-1
Chromosomal passenger complex protein bir-1; Component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of chromosome segregation and cytokinesis. The CPC complex has essential functions at the centromere in ensuring correct chromosome condensation, alignment and segregation. In the complex, required to direct the Aurora B/air-2 kinase to chromosomes. Also functions in spindle midzone formation and in the formation of polar bodies during oogenesis. Required for the localization of the kinetochore component hcp-1 to chromosomes. Involved in the positive [...]

csp-2
Putative inactive caspase B subunit p17; [Isoform b]: Putative inactive caspase. In the germline, binds caspase ced-3 zymogen and prevents ced-3 autoactivation. Does not affect the caspase activity of mature ced-3 and ced-4-mediated mature ced-3 activation. Negatively regulates germline apoptosis by inhibiting autocleavage of caspase ced-3. Involved in fertility ; Belongs to the peptidase C14A family.
   
 
0.490
cyc-2.2
Probable cytochrome c 2.2; Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain (By similarity).
