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

spel1DNA mismatch repair protein spellchecker 1; Involved in postreplication mismatch repair. Binds specifically to DNA containing mismatched nucleotides thus providing a target for the excision repair processes characteristic of postreplication mismatch repair (By similarity). (917 aa)    
Predicted Functional Partners:
Msh6
Probable DNA mismatch repair protein Msh6; Msh6 (Msh6) encodes a heterodimer with the product of spel1 to detect base-base mismatches and small insertion/deletion loops. It then recruits the rest of the mismatch repair machinery.
  
0.999
Pms2
Pms2; Mismatched DNA binding; ATPase activity; ATP binding. It is involved in the biological process described with: mismatch repair.
 
 0.993
Mlh1
Mlh1, isoform A; ATP binding; ATPase activity; mismatched DNA binding. It is involved in the biological process described with: mismatch repair.

tos
Exonuclease 1; 5'->3' double-stranded DNA exonuclease which may also contain a cryptic 3'->5' double-stranded DNA exonuclease activity. Also exhibits endonuclease activity against 5'-overhanging flap structures similar to those generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Required for DNA mismatch repair (MMR) (By similarity).
   
 0.983
Ercc1
Nucleotide excision repair protein ERCC1; Ercc1 (Ercc1) encodes the non-catalytic partner of the nuclease encoded by mei-9 that cuts structures formed during DNA repair. The mei-9-Ercc1 heterodimer interacts with the product of mus312 to make meiotic crossovers. The functions of the product of Ercc1 include repair of UV-induced DNA damage, repair of base adducts, a backup pathway for mismatch repair and meiotic recombination.

mei-9
DNA repair endonuclease XPF; Implicated in recombination events during meiosis, mostly in meiotic exchange. May directly resolve Holliday junctions within recombination intermediates leading to DNA exchange. Also required for the repair of mismatches within meiotic heteroduplex DNA and for nucleotide excision repair.
   
 0.937
PCNA
Proliferating cell nuclear antigen; Likely to be an auxiliary protein of DNA polymerase delta complex and is probably involved in the control of DNA replication and repair by increasing the polymerase's processibility. Belongs to the PCNA family.
   
 0.936
DNApol-delta
DNA polymerase delta catalytic subunit; As the catalytic component of the DNA polymerase delta complex, plays a crucial role in high fidelity genome replication, including lagging strand synthesis, DNA recombination and repair (By similarity). Exhibits both DNA polymerase and 3'- to 5'-exonuclease activities. Required at the nucleus of rapidly dividing embryonic cells to activate genome replication during the earliest cell cycles. Likely to require the presence of accessory proteins Pol31 and Pol32 for full 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 [...]

FBgn0264326
DNA polymerase epsilon catalytic subunit 1; Catalytic component of the DNA polymerase epsilon complex. Participates in chromosomal DNA replication. Required during synthesis of the leading DNA strands at the replication fork, binds at/or near replication origins and moves along DNA with the replication fork (By similarity). Has 3'-5' proofreading exonuclease activity that corrects errors arising during DNA replication. Has a role in the G1-S transition and/or S-phase progression of the mitotic cycle and endocycle progression. Involved in DNA synthesis during DNA repair (By similarity). [...]
