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

ced-4Cell 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 [...] (571 aa)    
Predicted Functional Partners:
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 [...]

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.

bir-2
Baculoviral IAP repeat-containing protein bir-2.
   
 0.947
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 [...]
   
 0.946
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 [...]

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.
   
 
 0.930
ran-2
Ran GTPase-activating protein 2; GTPase system comprising ran-1, ran-2 and ran-3 is essential in nucleocytoplasmic trafficking. Ran-2 is a GTPase activator for the nuclear RAS-related regulatory protein Ran, converting it to the putatively inactive GDP-bound state. Required for correct chromosome alignment and segregation on the metaphase plate.
   
 
 0.889
csp-3
Non-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.
    
 
 0.857
ced-1
Cell death abnormality protein 1; Involved in programmed cell death, also called apoptosis, in both somatic and germ cells. Acts by recruiting ced-6 to phagosomes which enables actin-dependent cytoskeletal reorganization and subsequent engulfment of the apoptotic cell corpse. Has a role in the association of ppk-3 and rab-7 with the phagosomal surface which is necessary for the incorporation of lysosomes to phagosomes during phagosome maturation. Activates the expression of unfolded protein response genes, which are involved in the immune response to live bacteria.

crt-1
Calreticulin; Molecular calcium-binding chaperone promoting folding, oligomeric assembly and quality control in the ER via the calreticulin/calnexin cycle (By similarity). This lectin may interact transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER (By similarity). Probably by controlling the folding of extracellular matrix protein unc-52/Perlecan, may play a role in the formation of fibrous organelles, a hemidesmosome-like structure attaching muscles to the epidermis. Protects dopaminergic neurons against oxidative stress-induced neurodegen [...]
