The encoded protein associates with CD40, tumor necrosis factor (TNF) receptor-75 and TNF receptor associated factors (TRAFs), and inhibits nuclear factor-kappa-B activation. This protein has sequence and structural similarities with APE1 endonuclease, which is involved in both DNA repair and the activation of transcription factors. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: DNA repair enzyme that can remove a variety of covalent adducts from DNA through hydrolysis of a 5'-phosphodiester bond, giving rise to DNA with a free 5' phosphate. Catalyzes the hydrolysis of dead-end complexes between DNA and the topoisomerase 2 (TOP2) active site tyrosine residue. The 5'-tyrosyl DNA phosphodiesterase activity can enable the repair of TOP2-induced DNA double-strand breaks/DSBs without the need for nuclease activity, creating a 'clean' DSB with 5'-phosphate termini that are ready for ligation. Thereby, protects the transcription of many genes involved in neurological development and maintenance from the abortive activity of TOP2. Hydrolyzes 5'- phosphoglycolates on protruding 5' ends on DSBs due to DNA damage by radiation and free radicals. Has preference for single-stranded DNA or duplex DNA with a 4 base pair overhang as substrate. Acts as a regulator of ribosome biogenesis following stress. Has also 3'-tyrosyl DNA phosphodiesterase activity, but less efficiently and much slower than TDP1. Constitutes the major if not only 5'- tyrosyl-DNA phosphodiesterase in cells. Also acts as an adapter by participating in the specific activation of MAP3K7/TAK1 in response to TGF-beta: associates with components of the TGF-beta receptor-TRAF6-TAK1 signaling module and promotes their ubiquitination dependent complex formation. Involved in non- canonical TGF-beta induced signaling routes. May also act as a negative regulator of ETS1 and may inhibit NF-kappa-B activation. {ECO:0000269|PubMed:19794497, ECO:0000269|PubMed:21030584, ECO:0000269|PubMed:21921940, ECO:0000269|PubMed:21980489, ECO:0000269|PubMed:22405347, ECO:0000269|PubMed:22822062, ECO:0000269|PubMed:24658003}. |Exo endo phos| |tyrosyl-RNA phosphodiesterase activity| |5-tyrosyl-DNA phosphodiesterase activity| |nuclease activity| |aggresome| |manganese ion binding| |PML body| |single-stranded DNA binding| |double-strand break repair| |magnesium ion binding| |transcription corepressor activity| |nuclear body| |nucleic acid phosphodiester bond hydrolysis| |DNA repair| |DNA metabolic process| |cellular response to DNA damage stimulus| |neuron development| |nucleolus| |neuron differentiation| |negative regulation of nucleic acid-templated transcription| |negative regulation of RNA biosynthetic process| |negative regulation of RNA metabolic process| |negative regulation of nucleobase-containing compound metabolic process| |negative regulation of macromolecule biosynthetic process| |negative regulation of cellular biosynthetic process| |generation of neurons| |negative regulation of biosynthetic process| |neurogenesis| |cell development| |cellular response to stress| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp198|Etoposide 0.1μM R05 exp198]]|-3.8| |[[:results:exp360|Genistein 15μM R07 exp360]]|-2.98| |[[:results:exp240|Pyridostatin 4μM R05 exp240]]|-2.25| |[[:results:exp357|Dorsomorphin 5μM R07 exp357]]|-2.03| |[[:results:exp69|Deguelin 0.05μM R02 exp69]]|-1.73| |[[:results:exp125|GSK461364A 0.005μM R03 exp125]]|1.87| |[[:results:exp42|BI-6727 0.001μM R01 exp42]]|2.08| ^Gene^Correlation^ |[[:human genes:z:znf451|ZNF451]]|0.404| Global Fraction of Cell Lines Where Essential: 4/726 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|1/25| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|1/13| |fibroblast|0/1| |gastric|0/15| |kidney|1/21| |liver|0/20| |lung|0/75| |lymphocyte|0/14| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/7| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 3494 * **Expression level (log2 read counts)**: 5.65 {{:chemogenomics:nalm6 dist.png?nolink |}}
