Summaries for POLI Gene

Entrez Gene Summary for POLI Gene

  • The protein encoded by this gene is an error-prone DNA polymerase involved in DNA repair. The encoded protein promotes DNA synthesis across lesions in the template DNA, which other polymerases cannot do. The encoded polymerase inserts deoxynucleotides across lesions and then relies on DNA polymerase zeta to extend the nascent DNA strand to bypass the lesion. [provided by RefSeq, May 2017]

GeneCards Summary for POLI Gene

POLI (DNA Polymerase Iota) is a Protein Coding gene. Diseases associated with POLI include Tracheitis and Xeroderma Pigmentosum, Variant Type. Among its related pathways are Translesion synthesis by Y family DNA polymerases bypasses lesions on DNA template and DNA Double-Strand Break Repair. GO annotations related to this gene include damaged DNA binding and DNA-directed DNA polymerase activity. An important paralog of this gene is POLH.

UniProtKB/Swiss-Prot for POLI Gene

  • 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.
