FunFam 1076: ATP-dependent DNA helicase MER3

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 5 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Heteroduplex DNA loop binding GO:0000404
Interacting selectively and non-covalently with DNA containing a loop. A loop occurs when DNA contains a large insertion or deletion that causes a region of unpaired single-stranded DNA to loop out, while the rest of the DNA is in a paired double-stranded configuration.
1 P51979 (/IDA)
DNA helicase activity GO:0003678
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction drives the unwinding of the DNA helix.
1 P51979 (/IDA)
DNA helicase activity GO:0003678
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction drives the unwinding of the DNA helix.
1 Q5D892 (/ISS)
Helicase activity GO:0004386
Catalysis of the reaction: ATP + H2O = ADP + phosphate, to drive the unwinding of a DNA or RNA helix.
1 Q381X2 (/ISM)
MutLbeta complex binding GO:0032406
Interacting selectively and non-covalently with the mismatch repair complex MutLbeta.
1 P51979 (/IPI)

There are 8 GO terms relating to "biological process"

GO Term Annotations Evidence
Reciprocal meiotic recombination GO:0007131
The cell cycle process in which double strand breaks are formed and repaired through a double Holliday junction intermediate. This results in the equal exchange of genetic material between non-sister chromatids in a pair of homologous chromosomes. These reciprocal recombinant products ensure the proper segregation of homologous chromosomes during meiosis I and create genetic diversity.
3 B6DMK2 (/IMP) P51979 (/IMP) Q5D892 (/IMP)
Resolution of meiotic recombination intermediates GO:0000712
The cleavage and rejoining of intermediates, such as Holliday junctions, formed during meiotic recombination to produce two intact molecules in which genetic material has been exchanged.
1 D3Z4R1 (/IMP)
Nucleobase-containing compound metabolic process GO:0006139
Any cellular metabolic process involving nucleobases, nucleosides, nucleotides and nucleic acids.
1 Q381X2 (/ISM)
DNA unwinding involved in DNA replication GO:0006268
The process in which interchain hydrogen bonds between two strands of DNA are broken or 'melted', generating unpaired template strands for DNA replication.
1 P51979 (/IDA)
Synapsis GO:0007129
The meiotic cell cycle process where side by side pairing and physical juxtaposition of homologous chromosomes is created during meiotic prophase. Synapsis begins when the chromosome arms begin to pair from the clustered telomeres and ends when synaptonemal complex or linear element assembly is complete.
1 P51979 (/IMP)
Chiasma assembly GO:0051026
The cell cycle process in which a connection between chromatids assembles, indicating where an exchange of homologous segments has taken place by the crossing-over of non-sister chromatids.
1 Q5D892 (/IMP)
Meiotic cell cycle GO:0051321
Progression through the phases of the meiotic cell cycle, in which canonically a cell replicates to produce four offspring with half the chromosomal content of the progenitor cell via two nuclear divisions.
1 P51979 (/IDA)
Protein localization to site of double-strand break GO:1990166
Any process in which a protein is transported to, or maintained at, a region of a chromosome at which a DNA double-strand break has occurred.
1 P51979 (/IMP)

GO Term Annotations Evidence
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

1 Q381X2 (/ISM)
Chromosome GO:0005694
A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information.
1 B6DMK2 (/IMP)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
