GeneCards Summary for POLI Gene
POLI (Polymerase (DNA Directed) Iota) is a Protein Coding gene. Diseases associated with POLI include tracheitis and balanoposthitis. Among its related pathways are DNA Double-Strand Break Repair and Translesion synthesis by Y family DNA polymerases bypasses lesions on DNA template. 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.
