Tyrosyl-DNA phosphodiesterase I (IPR010347)

Short name: Tdp1

Family relationships



Tyrosyl-DNA phosphodiesterase 1 (Tdp1) is a 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 [PMID: 12023295, PMID: 19505854].

Mutations in human TDP1 gene cause spinocerebellar ataxia, autosomal recessive, with axonal neuropathy (SCAN1), which is a clinically and genetically heterogeneous group of cerebellar disorders [PMID: 16141202].
