DNA repair, 10(9), 961-969 (2011-08-16)
CK2 phosphorylates the scaffold protein XRCC1, which is required for efficient DNA single-strand break (SSB) repair. Here, we express an XRCC1 protein (XRCC1(ckm)) that cannot be phosphorylated by CK2 in XRCC1 mutated EM9 cells and show that the role of

Pre-ribosomal particles undergo numerous structural changes during maturation, but their high complexity and short lifetimes make these changes very difficult to follow in vivo. In consequence, pre-ribosome structure and composition have largely been inferred from purified particles and analyzed in

Proteomics, 11(2), 249-260 (2011-01-05)
Protein footprinting is a new methodology that is based on probing, typically with the use of MS, of reactivity of different amino acid residues to a modifying reagent. Data thus obtained allow one to make inferences about protein conformations and
