Cul4 molecule helps to deposit DNA-packaging histone proteins onto DNA, an integral step in cramming yards of genetic code into compact coils that can fit into each cell. The research is published in the issue of the journal iCell/i. The results explain on a molecular level how Cul4 enables the handoff of histones from the proteins escorting them from their birthplace in the cell to their workplace on the DNA, where they can begin wrapping DNA up into tidy units called ...
