Summaries for POLI Gene

GeneCards Summary for POLI Gene

POLI (Polymerase (DNA) Iota) is a Protein Coding gene. Among its related pathways are Fanconi anemia pathway 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.

Q9UNA4

UniProtKB/Swiss-Prot:

POLI_HUMAN :
  • The catalytic core consists of fingers, palm and thumb subdomains, but the fingers and thumb subdomains are much smaller than in high-fidelity polymerases; residues from five sequence motifs of the Y-family cluster around an active site cleft that can accommodate DNA and nucleotide substrates with relaxed geometric constraints, with consequently higher rates of misincorporation and low processivity.
  • Belongs to the DNA polymerase type-Y family.
