What's a GeneRIF?

The results indicate that Polkappa does not suppress benzo[a]pyrene -induced mutagenesis and carcinogenesis in the colon, but counteracts inflammation-induced mutagenesis in multiple organs.
Title: DNA polymerase kappa counteracts inflammation-induced mutagenesis in multiple organs of mice.
The results suggest that Polk has a limited ability to suppress BP-induced genotoxicity in the colon and bone marrow and also that the roles of specialized DNA polymerases in mutagenesis and carcinogenesis should be examined not only by in vitro assays but also by in vivo mouse studies. We also report the spontaneous mutagenesis in inactivated Polk KI mice at young and old ages.
Title: Limited ability of DNA polymerase kappa to suppress benzo[a]pyrene-induced genotoxicity in vivo.
the extreme N-terminal part of Polkappa is required for the processivity and fidelity of Polkappa during translesion synthesis of 10S(+)-trans-anti-benzo[a]pyrene diol epoxide-N(2)-deoxyguanine adducts lesions.
Title: Effects of the N terminus of mouse DNA polymerase κ on the bypass of a guanine-benzo[a]pyrenyl adduct.
Polk plays a predominant role in suppressing point mutations by carrying out error-free translesion DNA synthesis and contributes to the prevention of DNA strand breaks.
Title: In vivo evidence that DNA polymerase kappa is responsible for error-free bypass across DNA cross-links induced by mitomycin C.
The structural gap physically accommodates the bulky aromatic adduct and the N-clasp is essential for the structural integrity and flexibility of Polkappa during translesion synthesis.
Title: Variants of mouse DNA polymerase κ reveal a mechanism of efficient and accurate translesion synthesis past a benzo[a]pyrene dG adduct.
Polkappa accumulates at laser-induced sites of DNA damage.
Title: Mouse DNA polymerase kappa has a functional role in the repair of DNA strand breaks.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NM_001347602.1 → NP_001334531.1 DNA polymerase kappa isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains lacks an alternate exon but contains a different in-frame exon in the central coding region, compared to variant a, resulting in an isoform (2) that is shorter than isoform a. The 5' UTR of this variant is incomplete because there are no 5'-complete transcripts representing it and there is splicing ambiguity at the 5' end.

NR_144622.1 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (1) uses an alternate splice site in the 3' region, compared to variant a. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant a, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD). The 5' end of this variant is incomplete because there are no 5'-complete transcripts representing it and there is splicing ambiguity at the 5' end.
