FunFam 9: DNA polymerase epsilon catalytic subunit A

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 4 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
DNA-directed DNA polymerase activity GO:0003887
Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1); the synthesis of DNA from deoxyribonucleotide triphosphates in the presence of a DNA template and a 3'hydroxyl group.
2 C6KTD8 (/ISS) C6KTD8 (/ISS)
DNA-directed DNA polymerase activity GO:0003887
Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1); the synthesis of DNA from deoxyribonucleotide triphosphates in the presence of a DNA template and a 3'hydroxyl group.

DNA-directed DNA polymerase activity GO:0003887
Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1); the synthesis of DNA from deoxyribonucleotide triphosphates in the presence of a DNA template and a 3'hydroxyl group.
1 P87154 (/IMP)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
1 P87154 (/IPI)

There are 9 GO terms relating to "biological process"

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
DNA-dependent DNA replication GO:0006261
A DNA replication process that uses parental DNA as a template for the DNA-dependent DNA polymerases that synthesize the new strands.
2 C6KTD8 (/ISS) C6KTD8 (/ISS)
Premeiotic DNA replication GO:0006279
The replication of DNA that precedes meiotic cell division.
1 P87154 (/IMP)
Chromatin organization GO:0006325
Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin.
1 P87154 (/IMP)
Regulation of chromatin silencing by small RNA GO:0010964
Any process that modulates the frequency, rate or extent of chromatin silencing by small RNA. Chromatin silencing by small RNA is the repression of transcription by conversion of large regions of DNA into heterochromatin, directed by small RNAs sharing sequence identity to the repressed region.
1 P87154 (/IMP)
Positive regulation of chromatin silencing at centromere GO:0090053
Any process that increases the frequency, rate or extent of chromatin silencing at the centromere. Chromatin silencing at the centromere is the repression of transcription of centromeric DNA by altering the structure of chromatin.
1 P87154 (/IMP)
Mitotic DNA replication initiation GO:1902975
Any DNA replication initiation involved in mitotic cell cycle DNA replication.
1 P87154 (/IMP)
DNA strand elongation involved in mitotic DNA replication GO:1902983
Any DNA strand elongation involved in mitotic cell cycle DNA replication.
1 P87154 (/IMP)
Regulation of CENP-A containing nucleosome assembly GO:1903097
Any process that modulates the rate, frequency or extent of the formation of nucleosomes containing the histone H3 variant CENP-A to form centromeric chromatin. This specialised chromatin occurs at centromeric region in point centromeres, and the central core in modular centromeres.
1 P87154 (/IMP)
Mitotic DNA replication leading strand elongation GO:1903460
Any leading strand elongation that is involved in mitotic cell cycle DNA replication.
1 P87154 (/IMP)

GO Term Annotations Evidence
Epsilon DNA polymerase complex GO:0008622
A heterotetrameric DNA polymerase complex that catalyzes processive DNA synthesis in the absence of PCNA, but is further stimulated in the presence of PCNA. The complex contains a large catalytic subunit and three small subunits, and is best characterized in Saccharomyces, in which the subunits are named Pol2p, Dpb2p, Dpb3p, and Dpb4p. Some evidence suggests that DNA polymerase epsilon is the leading strand polymerase; it is also involved in nucleotide-excision repair and mismatch repair.
2 C6KTD8 (/ISS) C6KTD8 (/ISS)
Nuclear chromosome, telomeric region GO:0000784
The terminal region of a linear nuclear chromosome that includes the telomeric DNA repeats and associated proteins.
1 P87154 (/IDA)
Epsilon DNA polymerase complex GO:0008622
A heterotetrameric DNA polymerase complex that catalyzes processive DNA synthesis in the absence of PCNA, but is further stimulated in the presence of PCNA. The complex contains a large catalytic subunit and three small subunits, and is best characterized in Saccharomyces, in which the subunits are named Pol2p, Dpb2p, Dpb3p, and Dpb4p. Some evidence suggests that DNA polymerase epsilon is the leading strand polymerase; it is also involved in nucleotide-excision repair and mismatch repair.
1 P87154 (/ISO)
Nuclear replication fork GO:0043596
The Y-shaped region of a nuclear replicating DNA molecule, resulting from the separation of the DNA strands and in which the synthesis of new strands takes place. Also includes associated protein complexes.
