AT1G01880 protein (Arabidopsis thaliana) - STRING interaction network
"AT1G01880" - 5'-3' exonuclease family protein in Arabidopsis thaliana
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:
some 3D structure is known or predicted
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
AT1G018805’-3’ exonuclease family protein; Endonuclease which cleaves flap structures at the junction between single-stranded DNA and double-stranded DNA; Belongs to the XPG/RAD2 endonuclease family. GEN subfamily (599 aa)    
Predicted Functional Partners:
Proliferating cell nuclear antigen 2; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase’s processibility during elongation of the leading strand (By similarity). May be involved in UV resistance; Belongs to the PCNA family (264 aa)
Proliferating cellular nuclear antigen 1; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase’s processibility during elongation of the leading strand; Belongs to the PCNA family (263 aa)
Restriction endonuclease, type II-like superfamily protein; Interacts with EME1 to form a DNA structure-specific endonuclease with substrate preference for branched DNA structures with a 5’-end at the branch nick. Typical substrates include 3’- flap structures, D-loops, replication forks, nicked Holliday junctions and also intact Holliday junctions with a reduced efficiency. May be required in mitosis for the processing of stalled or collapsed replication fork intermediates. Plays a role in DNA repair and in genotoxic stress-induced homologous recombination (HR) in somatic cells. Media [...] (659 aa)
DNA LIGASE 6; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair (Probable). Required to maintain seed viability (e.g. longevity and storability) and during seed germination, probably by repairing DNA damage accumulated during seed development, storage and/or imbibition. Faciliates seed germination in cold conditions (2 degrees Celsius) and under oxidative stress (e.g. menadione, a genotoxic agent). Involved in repair of X-ray-induced damage; Belongs to the ATP-dependent DNA ligase family (1396 aa)
DNA mismatch repair protein MSH2; Component of the post-replicative DNA mismatch repair system (MMR). Forms three different heterodimers- MutS alpha (MSH2-MSH6 heterodimer), MutS beta (MSH2-MSH3 heterodimer) and MutS gamma (MSH2-MSH7 heterodimer) which binds to DNA mismatches thereby initiating DNA repair. MutS alpha and MutS beta recognize single base mismatches and trinucleotide insertion-deletion loops (IDL) in the DNA. MutS gamma recognizes specifically the T/G single base mismatch. Plays a role in DNA homologous recombination repair and has a broad range of anti-recombination effe [...] (937 aa)
Transducin family protein / WD-40 repeat family protein; Contains the following InterPro domains- WD40 repeat 2 (InterPro-IPR019782), WD40 repeat, conserved site (InterPro-IPR019775), WD40 repeat (InterPro-IPR001680), WD40 repeat-like-containing domain (InterPro-IPR011046), Protein of unknown function DUF3639 (InterPro-IPR022100), WD40-repeat-containing domain (InterPro-IPR017986), WD40/YVTN repeat-like-containing domain (InterPro-IPR015943), WD40 repeat, subgroup (InterPro-IPR019781); BEST Arabidopsis thaliana protein match is- Transducin/WD40 repeat-like superfamily protein (TAIR-AT5 [...] (953 aa)
DNA mismatch repair protein MLH1; Involved in DNA mismatch repair (MMR), correcting insertion-deletion loops (IDLs) resulting from DNA replication, DNA damage or from recombination events between non-identical sequences during meiosis. Component of the MutLbeta heterodimer, which probably forms a ternary complex with the MutSbeta heterodimer that initially recognizes the DNA mismatches. This complex is thought to be responsible for directing the downsteam MMR events, including strand discrimination, excision, and resynthesis. Plays a major role in promoting meiotic crossing-over and is [...] (737 aa)
Nucleotide repair protein, putative; Seems to be involved in nucleotide excision repair (NER) of damaged DNA (dark repair mechanism). The UVH1/RAD1-ERCC1/RAD10 complex may act as an endonuclease making DNA incision 5’ to the lesion site. In vitro, is implicated in double strand breaks (DSBs) repair and is required for homologous recombination in the presence of non-homologous overhangs. In vitro, is involved in chromosomal recombination between tandem repeats in both direct and inverted orientations. May mediate the induction of a DNA- damage sensitive cell-cycle checkpoint during the [...] (410 aa)
Encodes the putative catalytic subunit of the DNA polymerase alpha. Interacts with genes involved in chromatin-mediated cellular memory. ICU2 genetically interacts with TERMINAL FLOWER2, the ortholog of HETEROCHROMATIN PROTEIN1 of animals and yeasts, and with the Polycomb group (PcG) gene CURLY LEAF. A number of regulatory genes were derepressed in the icu2-1 mutant, including genes associated with flowering time, floral meristem, and floral organ identity. Mutant has curled, involute leaves and causes early flowering (1524 aa)
Bifunctional dihydrofolate reductase-thymidylate synthase 2; Bifunctional enzyme. Involved in de novo dTMP biosynthesis. Key enzyme in folate metabolism. Can play two different roles depending on the source of dihydrofolate- de novo synthesis of tetrahydrofolate or recycling of the dihydrofolate released as one of the end products of the TS catalyzed reaction. Catalyzes an essential reaction for de novo glycine and purine synthesis, DNA precursor synthesis, and for the conversion of dUMP to dTMP; In the C-terminal section; belongs to the thymidylate synthase family (565 aa)
