RECQ4A protein (Arabidopsis thaliana) - STRING interaction network
"RECQ4A" - ATP-dependent DNA helicase Q-like 4A 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
RECQ4AATP-dependent DNA helicase Q-like 4A; 3’-5’ DNA helicase that may play a role in the repair of DNA. Required for maintenance of genome stability by modulation of the DNA damage response and repression of crossovers. Confers resistance to genotoxic stress (1188 aa)    
Predicted Functional Partners:
Topoisomerase 3alpha; Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5’-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3’-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand thus removing DNA supercoils. Fina [...] (926 aa)
MMS AND UV SENSITIVE 81; 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. Mediates a subset of meiotic recombinati [...] (659 aa)
MUTS-homologue 5; Involved in meiotic recombination in association with MSH4. Required for reciprocal recombination and proper segregation of homologous chromosomes at meiosis. Promotes homologous recombination through facilitating chiasma formation during prophase I. Involved in the control of class I crossovers formation (807 aa)
Fanconi anemia group M protein (1390 aa)
Serine/threonine-protein kinase ATR; Probable serine/threonine kinase. Plays a central role in cell-cycle regulation by transmitting DNA damage signals to downstream effectors of cell-cycle progression. May recognize the substrate consensus sequence [ST]-Q and phosphorylate histone variant H2AX to form H2AXS139ph at sites of DNA damage, thereby regulating DNA damage response mechanism. Seems to be required for the G2-phase checkpoint in response to replication blocks but not absolutely required in the G2-arrest response to double-strand breaks. May also be involved in the meiosis proce [...] (2702 aa)
Topoisomerase II; Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks (1473 aa)
DNA topoisomerase, type IA, core (1284 aa)
KU70 homolog; Single-stranded DNA-dependent ATP-dependent helicase. Involved in DNA non-homologous end joining (NHEJ) required for double-strand break repair. When associated with KU80, binds to double-stranded telomeric and non-telomeric DNA sequences, but not to single-stranded DNA. Plays a role in maintaining telomere length. Acts as a negative regulator of telomerase. Required for maintenance of the telomeric C-rich strand (621 aa)
DNA repair protein RAD51-like 1; Binds to single and double-stranded DNA and exhibits DNA-dependent ATPase activity. Unwinds duplex DNA (By similarity). Component of the meiotic recombination pathway. Seems to play a role in mediating chromosome homology search, chromosome pairing and synapsis at early stages and probably chromosome crossing-over at later stages in meiosis. Probably is involved in the repair of meiotic double strand breaks (DBSs) generated by AtSPO11-1 and in homologous recombination. Its function is dispensable for vegetative growth and root mitosis (342 aa)
Uncharacterized protein (677 aa)
