Journal Article
Battaglia, R. A., Beltran, A. S., Delic, S., Dumitru, R., Robinson, J. A., Kabiraj, P., …Snider, N. T. (2019). Site-specific phosphorylation and caspase cleavage of GFAP are new markers of Alexander Disease severity. eLife, 8, Article e47789. https://doi.org/10.7554/elife.47789

Alexander Disease (AxD) is a fatal neurodegenerative disorder caused by mutations in glial fibrillary acidic protein (GFAP), which supports the structural integrity of astrocytes. Over 70 GFAP missense mutations cause AxD, but the mechanism linking d... Read More about Site-specific phosphorylation and caspase cleavage of GFAP are new markers of Alexander Disease severity.

Inverse dose-rate effect of ionising radiation on residual 53BP1 foci in the eye lens (2019)
Journal Article
Barnard, S., McCarron, R., Moquet, J., Quinlan, R., & Ainsbury, E. (2019). Inverse dose-rate effect of ionising radiation on residual 53BP1 foci in the eye lens. Scientific Reports, 9, Article 10418. https://doi.org/10.1038/s41598-019-46893-3

The influence of dose rate on radiation cataractogenesis has yet to be extensively studied. One recent epidemiological investigation suggested that protracted radiation exposure increases radiation-induced cataract risk: cumulative doses of radiation...

BFSP1 C-terminal domains released by post-translational processing events can alter significantly the calcium regulation of AQP0 water permeability (2019)
Journal Article
Tapodi, A., Clemens, D., Uwineza, A., Goldberg, M., Thinon, E., Heal, W., …Quinlan, R. (2019). BFSP1 C-terminal domains released by post-translational processing events can alter significantly the calcium regulation of AQP0 water permeability. Experimental Eye Research, 185, Article 107585. https://doi.org/10.1016/j.exer.2019.02.001

BFSP1 (beaded filament structural protein 1, filensin) is a cytoskeletal protein expressed in the eye lens. It binds AQP0 in vitro and its C-terminal sequences have been suggested to regulate the water channel activity of AQP0. A myristoylated fragme...

Cataractogenic load – a concept to study the contribution of ionizing radiation to accelerated aging in the eye lens (2019)
Journal Article

Mutation Research/Reviews in Mutation Research, 779, 68-81. https://doi.org/10.1016/j.mrrev.2019.02.004

Ionizing radiation (IR) damages DNA and other macromolecules, including proteins and lipids. Most cell types can repair DNA damage and cycle continuously their macromolecules as a mechanism to remove defective proteins and lipids. In those cells that...

Bacterial sensors define intracellular free energies for correct enzyme metalation (2019)
Journal Article
Osman, D., Martini, M. A., Foster, A. W., Chen, J., Scott, A. J., Morton, R. J., …Robinson, N. J. (2019). Bacterial sensors define intracellular free energies for correct enzyme metalation. Nature Chemical Biology, 15(3), 241-249. https://doi.org/10.1038/s41589-018-0211-4

There is a challenge for metalloenzymes to acquire their correct metals because some inorganic elements form more stable complexes with proteins than do others. These preferences can be overcome provided some metals are more available than others. Ho... Read More about Bacterial sensors define intracellular free energies for correct enzyme metalation.
