The Cellular Role Of Tyrosyl-Dna Phosphodiesterase 1 N-Terminal Domain In Topoisomerase 2-Dna Covalent Complex Repair In Yeast, Isaac Andres Segura

All ETDs from UAB

Tyrosyl-DNA phosphodiesterase 1 (Tdp1) removes adducts from DNA-ends, including damaged nucleotides and protein-DNA crosslinks such as DNA topoisomerases (Topo1 and Topo2) and Tdp1 itself. The N-terminal domain (NTD) of Tdp1 has been understudied, structurally unresolved, and seemingly dispensable for in vitro catalytic activity. However, our lab made the novel observation that the NTD is critical for Tdp1 cellular activity in removing Topo1-DNA covalent complexes (Topo1cc). Removal of the first 80 residues (yeast Tdp1 NTD) results in the loss of the toxic phenotype induced by full-length Tdp1 catalytic mutants. This suggests that in cells the NTD has a critical function in …
