DNA interstrand crosslink repair in mammalian cells.
DNA damage by agents crosslinking the strands presents a formidable challenge to the cell to repair for survival and to repair accurately for maintenance of genetic information. It appears that repair of DNA crosslinks occurs in a path involving double strand breaks (DSBs) in the DNA. Mammalian cells have multiple systems involved in the repair response to such damage, including the Fanconi ane...
متن کاملREV1 and DNA polymerase zeta in DNA interstrand crosslink repair.
DNA interstrand crosslinks (ICLs) are covalent linkages between two strands of DNA, and their presence interferes with essential metabolic processes such as transcription and replication. These lesions are extremely toxic, and their repair is essential for genome stability and cell survival. In this review, we will discuss how the removal of ICLs requires interplay between multiple genome maint...
متن کاملThe role of ADP-ribosylation in regulating DNA interstrand crosslink repair
ADP-ribosylation by ADP-ribosyltransferases (ARTs) has a well-established role in DNA strand break repair by promoting enrichment of repair factors at damage sites through ADP-ribose interaction domains. Here, we exploit the simple eukaryote Dictyostelium to uncover a role for ADP-ribosylation in regulating DNA interstrand crosslink repair and redundancy of this pathway with non-homologous end-...
متن کاملMechanism of Replication-Coupled DNA Interstrand Crosslink Repair
DNA interstrand crosslinks (ICLs) are toxic DNA lesions whose repair occurs in the S phase of metazoans via an unknown mechanism. Here, we describe a cell-free system based on Xenopus egg extracts that supports ICL repair. During DNA replication of a plasmid containing a site-specific ICL, two replication forks converge on the crosslink. Subsequent lesion bypass involves advance of a nascent le...
متن کاملFANCD2 Hurdles the DNA Interstrand Crosslink
Left unrepaired, DNA interstrand crosslinks represent impassable hurdles for DNA replication, and their removal is a complicated stepwise process involving a variety of enzymes. In a recent paper in Science, Knipscheer et al. (2009) demonstrate that the Fanconi Anemia protein FANCD2 promotes multiple steps of the crosslink repair process.
