Publications
Targets downstream of Cdk8 in Dictyostelium developmentDavid M Greene
Biochemistry Department, Oxford University, South Parks Road, Oxford OX1 3QU UK
BMC Dev Biol 11:2. 2011..Strains in which the gene encoding Cdk8 have been disrupted fail to form multicellular aggregates unless supplied with exogenous pulses of cAMP and later in development, cdk8- cells show a defect in spore production...
Differential roles of the PKC novel isoforms, PKCdelta and PKCepsilon, in mouse and human plateletsCatherine J Pears
Department of Biochemistry, University of Oxford, Oxford, United Kingdom
PLoS ONE 3:e3793. 2008..Increasing evidence suggests that individual isoforms of protein kinase C (PKC) play distinct roles in regulating platelet activation...
Submaximal inhibition of protein kinase C restores ADP-induced dense granule secretion in platelets in the presence of Ca2+Amanda J Unsworth
Department of Biochemistry, University of Oxford, Oxford OX1 3QU, United Kingdom
J Biol Chem 286:21073-82. 2011..These results also demonstrate isoform-specific inhibitory effects of PKC in platelets...
The role of ADP-ribosylation in regulating DNA double-strand break repairCatherine J Pears
Department of Biochemistry, University of Oxford, Oxford, UK
Cell Cycle 11:48-56. 2012..The implications of these data with regards to how ADP-ribosylation regulates DNA repair and genome stability are discussed...
PARP regulates nonhomologous end joining through retention of Ku at double-strand breaksC Anne Marie Couto
Department of Biochemistry, University of Oxford, England, UK
J Cell Biol 194:367-75. 2011..Furthermore, a PAR interaction motif in Ku70 was required for this regulation and efficient NHEJ. These data illustrate that PARylation at DSBs promotes NHEJ through recruitment or retention of repair factors at sites of DNA damage...
DNA damage signaling and repair in Dictyostelium discoideumDuen Wei Hsu
Department of Biochemistry, University of Oxford, Oxford, UK
Cell Cycle 5:702-8. 2006....
DNA double-strand break repair pathway choice in DictyosteliumDuen Wei Hsu
Department of Biochemistry, University of Oxford, South Parks Road, Oxford OX1 3QU, UK
J Cell Sci 124:1655-63. 2011..These data illustrate a functional NHEJ pathway in vegetative Dictyostelium and the importance of Ku in regulating DSB repair choice during this phase of the life cycle...
PKD: a new protein kinase C-dependent pathway in plateletsMargaret J Stafford
Department of Biochemistry, University of Oxford, United Kingdom
Blood 101:1392-9. 2003..This study shows that PKD is rapidly activated by a wide variety of platelet agonists through a PKC-dependent pathway. Activation of PKD enables phosphorylation of a distinct set of substrates to those targeted by PKC in platelets...
Control of cyclin C levels during development of DictyosteliumDavid M Greene
Department of Biochemistry, University of Oxford, Oxford, United Kingdom
PLoS ONE 5:e10543. 2010..Cells in which the gene encoding Cdk8 has been deleted fail to enter aggregates due to a failure of early gene expression...
Distinct but critical roles for integrin alphaIIbbeta3 in platelet lamellipodia formation on fibrinogen, collagen-related peptide and thrombinKelly Thornber
Department of Biochemistry, University of Oxford, UK
FEBS J 273:5032-43. 2006..These results suggest that integrins may play an important role in lamellipodia formation triggered by nonintegrin ligands in platelets and possibly in other cell types...
Dynamic acetylation of lysine-4-trimethylated histone H3 and H3 variant biology in a simple multicellular eukaryoteDuen Wei Hsu
Nuclear Signalling Laboratory, University of Oxford, South Parks Road, Oxford OX1 3QU, UK
Nucleic Acids Res 40:7247-56. 2012..These studies confirm that dynamic acetylation targeted to H3K4me3 arose early in evolution and reveal a very high level of specificity of histone variant utilization in a simple multicellular eukaryote...
DNA-PKcs-dependent signaling of DNA damage in Dictyostelium discoideumJessica J R Hudson
Department of Biochemistry, University of Oxford, South Parks Road, Oxford OX1 3QU, United Kingdom
Curr Biol 15:1880-5. 2005..These data illustrate a cell cycle-dependent requirement for Dictyostelium DNA-PK in signaling and combating DNA DSBs and represent the first experimental verification of DNA-PKcs in a nonvertebrate organism...
Developmental decisions in Dictyostelium discoideumLana Strmecki
Department of Biochemistry, University of Oxford, South Parks Road, Oxford OX1 3QU, UK
Dev Biol 284:25-36. 2005....
Investigation of DNA repair pathway activityAnne Marie C Couto
Department of Biochemistry, University of Oxford, Oxford, UK
Methods Mol Biol 983:295-310. 2013..Finally, we also describe more direct assays to assess repair of DNA double-strand breaks by either homologous recombination or non-homologous end joining...
