Human cells are prone to a range of natural environmental stresses and administered agents that damage or modify DNA, resulting in a cellular response typified by either cell death, or a cell cycle arrest, to permit repair of the genomic damage. DNA damage often elicits movement of proteins from one subcellular location to another, and the redistribution of proteins involved in genomic maintenance into distinct nuclear DNA repair foci is well documented. In this review, we discuss the DNA damage-induced trafficking of proteins to and from other distinct subcellular organelles including the nucleolus, mitochondria, Golgi complex and centrosome. The extent of intracellular transport suggests a dynamic and possibly co-ordinated role for protein trafficking in the DNA damage response. (c) 2007 Elsevier Inc. All rights reserved.
