CSB interacts with SNM1A and promotes DNA interstrand crosslink processing.
Cockayne syndrome (CS) is a premature aging disorder characterized by photosensitivity, impaired development and multisystem progressive degeneration, and consists of two strict complementation groups, A and B. Using a yeast two-hybrid approach, we identified the 5'-3' exonuclease SNM1A as one of four strong interacting partners of CSB. This direct interaction was confirmed using purified recombinant proteins-with CSB able to modulate the exonuclease activity of SNM1A on oligonucleotide subst...Expand abstract
