Role of tyrosyl-DNA phosphodiesterase (TDP1) in mitochondria.

Abstract

Human tyrosyl-DNA phosphodiesterase (TDP1) hydrolyzes the phosphodiester bond at a DNA 3'-end linked to a tyrosyl moiety and has been implicated in the repair of topoisomerase I (Top1)-DNA covalent complexes. TDP1 can also hydrolyze other 3'-end DNA alterations including 3'-phosphoglycolate and 3'-abasic sites, and exhibits 3'-nucleosidase activity… (More)
