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. {ECO:0000269|PubMed:11013228, ECO:0000269|PubMed:11251121, ECO:0000269|PubMed:11387224, ECO:0000269|PubMed:12410315, ECO:0000269|PubMed:14630940, ECO:0000269|PubMed:15199127, ECO:0000269|PubMed:15254543}. |IMS| |IMS C| |error-prone translesion synthesis| |DNA-directed DNA polymerase activity| |translesion synthesis| |DNA synthesis involved in DNA repair| |postreplication repair| |damaged DNA binding| |cytoplasmic ribonucleoprotein granule| |intracellular| |DNA biosynthetic process| |DNA replication| |nuclear speck| |DNA repair| |DNA metabolic process| |cellular response to DNA damage stimulus| |nucleobase-containing compound biosynthetic process| |heterocycle biosynthetic process| |aromatic compound biosynthetic process| |organic cyclic compound biosynthetic process| |cellular nitrogen compound biosynthetic process| |cellular response to stress| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp133|MKC9989 10μM R03 exp133]]|-2.07| |[[:results:exp493|IL-3 9ng/ml R08 exp493]]|1.72| |[[:results:exp53|Suberoylanilide-Hydroxamic-Acid 0.02μM R01 exp53]]|1.75| |[[:results:exp40|2-Methoxyestradiol 0.2μM R01 exp40]]|1.78| |[[:results:exp16|DABN 2μM R00 exp16]]|1.94| ^Gene^Correlation^ |[[:human genes:v:vasn|VASN]]|0.43| |[[:human genes:r:rrm1|RRM1]]|0.428| |[[:human genes:s:stil|STIL]]|0.414| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 3870 * **Expression level (log2 read counts)**: 4.33 {{:chemogenomics:nalm6 dist.png?nolink |}}
