title: The CUL4 enigma: culling DNA repair factors.
abstract: Although CUL4-containing ubiquitin ligases regulate DNA repair and DNA damage checkpoints, Liu et al. (2009) report in this issue of Molecular Cell that Cul4a-deficient mice exhibit surprising resistance to ultraviolet-induced skin tumors, providing insight into how ubiquitination regulates genome integrity.
