The role of ADP-ribosylation in regulating DNA interstrand crosslink repair [PDF]
, 2016 ADP-ribosylation by ADP-ribosyltransferases (ARTs) has a wellestablished role in DNA strand break repair by promoting enrichment of repair factors at damage sites through ADP-ribose interaction domains. Here, we exploit the simple eukaryote Dictyostelium

Characterization of a Distinct Plasma Membrane Macrodomain in Differentiated Adipocytes [PDF]
Journal of Biological Chemistry, 2002 Caveolae are small invaginations of the cell surface that are abundant in mature adipocytes. A recent study (Kanzaki, M., and Pessin, J. E. (2002) J. Biol. Chem. 277, 25867-25869) described novel caveolin- and actin-containing structures associated with the adipocyte cell surface that contain specific signaling proteins.

Visualization of poly(ADP-ribose) bound to PARG reveals inherent balance between exo- and endo-glycohydrolase activities [PDF]
, 2013 Poly-ADP-ribosylation is a post-translational modification that regulates processes involved in genome stability. Breakdown of the poly(ADP-ribose) (PAR) polymer is catalysed by poly(ADP-ribose) glycohydrolase (PARG), whose endo-glycohydrolase activity ...

Dielectric behavior and phase transition in [111]-oriented PIN–PMN–PT single crystals under dc bias [PDF]
Journal of Advanced Dielectrics, 2014 Temperature and electric field dependences of the dielectric behavior and phase transition for [111]-oriented 0.23PIN–0.52PMN–0.25PT (PIN-PMN–0.25PT) and 0.24PIN–0.43PMN–0.33PT (PIN–PMN–0.33PT) single crystals were investigated over a temperature range ...

Bacterial Chromosome Organization and Segregation [PDF]
, 2018 If fully stretched out, a typical bacterial chromosome would be nearly 1 mm long, approximately 1,000 times the length of a cell. Not only must cells massively compact their genetic material, but they must also organize their DNA in a manner that is ...

Correction: Mitochondrial Ceramide-Rich Macrodomains Functionalize Bax upon Irradiation
PLOS ONE, 2015 The authors would like to correct Fig 5, as errors were introduced in the preparation of this figure for publication. In Fig 5D[b], the image for the Light fraction Bak Western blot and the numbering of the fractions are incorrect. The authors have provided a corrected version of Fig 5 here. Fig 5 Ceramide induces formation of a mitochondrial

Structure of macrodomain walls in polytwinned magnets
Journal of Applied Physics, 2002 We propose a microscopic approach to the studies of magnetic configurations in hard magnets which may be conveniently used for nanoscale systems; the microstructure of the magnet is easily and naturally included in the calculations. This approach is applied to find the structure of macrodomain walls in polytwinned magnets of the CoPt family ...
