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

ParpPoly [ADP-ribose] polymerase; Poly-ADP-ribosyltransferase that mediates poly-ADP- ribosylation of proteins and plays a key role in DNA repair. Mainly mediates glutamate and aspartate ADP-ribosylation of target proteins: the ADP-D-ribosyl group of NAD(+) is transferred to the acceptor carboxyl group of glutamate and aspartate residues and further ADP- ribosyl groups are transferred to the 2'-position of the terminal adenosine moiety, building up a polymer with an average chain length of 20-30 units. (994 aa)    
Predicted Functional Partners:
Parg
Poly(ADP-ribose) glycohydrolase (Parg) encodes a nuclear enzyme that degrades poly(ADP-ribose) to mono(ADP-ribose) from the acceptor proteins after their modification by the product of Parp. It performs several vital roles, including regulation of developmental patterning and germ-line stem cell fate.
  
 
 0.995
Decay
Death executioner caspase related to Apopain/Yama (Decay) encodes one of the seven members of the caspase family of cysteine proteases. It has substrate specificity similar to the effector caspases encoded by Drice and Dcp-1; Belongs to the peptidase C14A family.
    
 0.992
Drice
Caspase subunit p12; Death related ICE-like caspase (Drice) encodes a major effector apoptotic caspase. It is essential for both developmental and damaged induced cell death, as well as several non-apoptotic vital cellular processes. It is activated by the product of Dark and the initiator caspase encoded by Dronc and is inhibited by the inhibitor of apoptosis encoded by Diap1; Belongs to the peptidase C14A family.
    
 0.965
Ku80
ATP-dependent DNA helicase II subunit 2; Ku80 (Ku80) encodes a protein that forms a Ku heterodimer with the product of Irbp, which binds to DNA double-strand break ends and is required for the non-homologous end joining pathway of DNA repair.
   
 
 0.963
CG1218
Histone PARylation factor 1-like; Histone binding; zinc ion binding; poly-ADP-D-ribose binding. It is involved in the biological process described with: peptidyl-serine ADP-ribosylation; cellular response to DNA damage stimulus; regulation of protein ADP-ribosylation; Belongs to the HPF1 family.
   
 
 0.930
Brca2
Breast cancer type 2 susceptibility protein homolog; BRCA2, DNA repair associated (Brca2) encodes the ortholog of the human BRCA2 gene, which acts as a tumor suppressor. It is involved in double-strand break repair via homologous recombination. During meiosis in females it is involved in DNA repair and in the activation of a meiotic checkpoint. It co-immunoprecipitates with the checkpoint protein encoded by Rad9.
    
 
 0.927
XRCC1
XRCC1 protein; Damaged DNA binding. It is involved in the biological process described with: base-excision repair; single strand break repair.
   
 
 0.924
Irbp
ATP-dependent DNA helicase 2 subunit 1; Single-stranded DNA-dependent ATP-dependent helicase. Involved in non-homologous end joining (NHEJ) DNA double strand break repair (By similarity). Sequence-specific DNA-binding protein that has a high affinity for a 31 bp sequence in the Yp1 gene. Site-specific DNA binding to 31 bp P element inverted repeats.
   
 
 0.917
DNAlig4
DNA ligase 4 (DNAlig4) encodes an ATP-dependent DNA ligase responsible for the sealing of DNA double-strand breaks during the canonical non-homologous end joining pathway of DNA repair. It interacts with the product of XRCC4 for stability and DNA ligase activity.

Fen1
Flap endonuclease 1; Structure-specific nuclease with 5'-flap endonuclease and 5'- 3' exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. It enters the flap from the 5'-end and then tracks to cleave the flap base, leaving a nick for ligation. Also involved in the long patch base excision repair (LP-BER) pathway, by cleaving within the apurinic/apyrimidinic (AP) site- terminated flap. Acts as [...]
