Error-prone DNA polymerase specifically involved in DNA repair. Plays an important role in translesion synthesis, where the normal high-fidelity DNA polymerases cannot proceed and DNA synthesis stalls. Favors Hoogsteen base-pairing in the active site. Inserts the correct base with high-fidelity opposite an adenosine template. Exhibits low fidelity and efficiency opposite a thymidine template, where it will preferentially insert guanosine. May play a role in hypermutation of immunogobulin genes. Forms a Schiff base with 5'-deoxyribose phosphate at abasic sites, but may not have lyase activity.
Gene References into Functions
Pol iota occasionally accesses the replication fork to generate a first mutation, and Pol zeta extends the mismatch with a second mutation.PMID:27455952
Mouse DNA polymerase iota lacking exon 2 (42 amino acids) is catalytically inactive in vitro.PMID:28077247
Exon 2 deletion abrogates both the DNA polymerase and dRP lyase activities of Pol iota in the presence of either Mg(2+) or Mn(2+) ions. Thus, 129-derived strains of mice express catalytically inactive alternatively spliced Pol iota variant.PMID:28077248
PolH contributes to accurate translesion synthesis (TLS) past both T- & C-containing dimers. PolI is involved in error-prone TLS past cytosine-containing dimers when Poleta is inactivated.PMID:25733082
Poliota causes the Par2 effect and inhibits tumorigenesis and mutagenesisPMID:23955086
in mammalian cells, both polymerases kappa and iota are necessary for the error-free bypass of N(2)-CEdG and N(2)-CMdG.PMID:21454642
Upon DNA damage, the UBDs (UBM domains) of polymerase iota (Pol iota) interact with ubiquitinated proliferating cell nuclear antigen to regulate the interchange between processive DNA polymerases and translesional synthesisPMID:20929865
In the presence of Mg2+, the enzyme was active only in testicles and brain, whereas in the presence of Mn2+ the activity was found in all organs.PMID:20673215
Data suggest that either DNA polymerase iota does not participate in hypermutation, or its role is nonessential and can be readily assumed by another low-fidelity polymerase.PMID:12925679
