TDP1 is a nuclear enzyme that hydrolyzes 3'-phosphotyrosyl bonds, releasing topoisomerase I from stalled cleavage complexes. The protein belongs to the phospholipase D family and requires two histidine motifs for catalysis. TDP1 is essential for resolving topoisomerase I-mediated DNA damage and preventing replication stress.
The Tyrosyl-DNA Phosphodiesterase 1 (TDP1) has the following structural features:
Available PDB structures: 3O10, 4OWD, 4OWE
TDP1 plays critical roles in:
TDP1 dysfunction contributes to:
| Disease | Mechanism |
