Abstract:
Cockayne syndrome protein A is one of the main components in mammalian transcription coupled repair. Here, the overproduction, purification and crystallization of human Cockayne syndrome protein A in complex with its interacting partner DNA damage binding protein 1 are reported. The complex was coproduced in insect cells, copurified and crystallized using sitting drops with PEG 3350 and sodium citrate as crystallizing agents. The crystals had unit-cell parameters a = b = 142.03, c = 250.19 Å and diffracted to 2.9 Å resolution on beamline ID14-1 at the European Synchrotron Radiation Facility.
