== Disease ==
[https://www.uniprot.org/uniprot/TYDP1_HUMAN TYDP1_HUMAN] Defects in TDP1 are the cause of spinocerebellar ataxia autosomal recessive with axonal neuropathy (SCAN1) [MIM:[https://omim.org/entry/607250 607250]. SCAN1 is an autosomal recessive cerebellar ataxia (ARCA) associated with peripheral axonal motor and sensory neuropathy, distal muscular atrophy, pes cavus and steppage gait as seen in Charcot-Marie-Tooth neuropathy. All affected individuals have normal intelligence.<ref>PMID:16141202</ref> <ref>PMID:15647511</ref> <ref>PMID:12244316</ref> <ref>PMID:17948061</ref> <ref>PMID:15920477</ref> 
== Function ==
[https://www.uniprot.org/uniprot/TYDP1_HUMAN TYDP1_HUMAN] DNA repair enzyme that can remove a variety of covalent adducts from DNA through hydrolysis of a 3'-phosphodiester bond, giving rise to DNA with a free 3' phosphate. Catalyzes the hydrolysis of dead-end complexes between DNA and the topoisomerase I active site tyrosine residue. Hydrolyzes 3'-phosphoglycolates on protruding 3' ends on DNA double-strand breaks due to DNA damage by radiation and free radicals. Acts on blunt-ended double-strand DNA breaks and on single-stranded DNA. Has low 3'exonuclease activity and can remove a single nucleoside from the 3'end of DNA and RNA molecules with 3'hydroxyl groups. Has no exonuclease activity towards DNA or RNA with a 3'phosphate.<ref>PMID:12023295</ref> <ref>PMID:15111055</ref> <ref>PMID:15811850</ref> <ref>PMID:16141202</ref> <ref>PMID:22822062</ref>
