FunFam 8: Proliferating cell nuclear antigen

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 3 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.

There are 13 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
Translesion synthesis GO:0019985
The replication of damaged DNA by synthesis across a lesion in the template strand; a specialized DNA polymerase or replication complex inserts a defined nucleotide across from the lesion which allows DNA synthesis to continue beyond the lesion. This process can be mutagenic depending on the damaged nucleotide and the inserted nucleotide.

Response to toxic substance GO:0009636
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a toxic stimulus.
2 B5X7E7 (/IDA) B9EMQ6 (/IDA)
DNA strand elongation involved in DNA replication GO:0006271
The process in which an existing DNA strand is extended by activities including the addition of nucleotides to the 3' end of the strand, complementary to an existing template, as part of DNA replication.
1 Q03392 (/IDA)
Postreplication repair GO:0006301
The conversion of DNA-damage induced single-stranded gaps into large molecular weight DNA after replication. Includes pathways that remove replication-blocking lesions in conjunction with DNA replication.
1 Q03392 (/IGI)
Response to bacterium GO:0009617
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a bacterium.
1 Q9PTP1 (/IDA)
Response to activity GO:0014823
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an activity stimulus.
1 Q9PTP1 (/IDA)
Error-prone translesion synthesis GO:0042276
The conversion of DNA-damage induced single-stranded gaps into large molecular weight DNA after replication by using a specialized DNA polymerase or replication complex to insert a defined nucleotide across the lesion. This process does not remove the replication-blocking lesions and causes an increase in the endogenous mutation level. For example, in E. coli, a low fidelity DNA polymerase, pol V, copies lesions that block replication fork progress. This produces mutations specifically targeted to DNA template damage sites, but it can also produce mutations at undamaged sites.
1 Q03392 (/IMP)
UV-damage excision repair GO:0070914
A DNA repair process that is initiated by an endonuclease that introduces a single-strand incision immediately 5' of a UV-induced damage site. UV-damage excision repair acts on both cyclobutane pyrimidine dimers (CPDs) and pyrimidine-pyrimidone 6-4 photoproducts (6-4PPs).
1 Q03392 (/IDA)
Error-free translesion synthesis GO:0070987
The conversion of DNA-damage induced single-stranded gaps into large molecular weight DNA after replication by using a specialized DNA polymerase or replication complex to insert a defined nucleotide across the lesion. This process does not remove the replication-blocking lesions but does not causes an increase in the endogenous mutation level. For S. cerevisiae, RAD30 encodes DNA polymerase eta, which incorporates two adenines. When incorporated across a thymine-thymine dimer, it does not increase the endogenous mutation level.
1 Q03392 (/IMP)
Positive regulation of DNA-directed DNA polymerase activity GO:1900264
Any process that activates or increases the frequency, rate or extent of DNA-directed DNA polymerase activity.
1 Q03392 (/IDA)
Positive regulation of cellular protein catabolic process GO:1903364
Any process that activates or increases the frequency, rate or extent of cellular protein catabolic process.
1 Q03392 (/IMP)
Mitotic DNA replication lagging strand elongation GO:1903459
Any lagging strand elongation that is involved in mitotic cell cycle DNA replication.
1 Q03392 (/IMP)
Mitotic DNA replication leading strand elongation GO:1903460
Any leading strand elongation that is involved in mitotic cell cycle DNA replication.
1 Q03392 (/ISO)

Site of double-strand break GO:0035861

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.
1 Q03392 (/IDA)
PCNA complex GO:0043626
A protein complex composed of three identical PCNA monomers, each comprising two similar domains, which are joined in a head-to-tail arrangement to form a homotrimer. Forms a ring-like structure in solution, with a central hole sufficiently large to accommodate the double helix of DNA. Originally characterized as a DNA sliding clamp for replicative DNA polymerases and as an essential component of the replisome, and has also been shown to be involved in other processes including Okazaki fragment processing, DNA repair, translesion DNA synthesis, DNA methylation, chromatin remodeling and cell cycle regulation.
