A PhD studentship is available immediately at the University of Liverpool.
Ph.D. in Structural Biology of Metalloproteins Project: Structure based insights and interventions into SOD1-related motor neuron disease Stipend: £13,000 per annum More than 100 mutations of Cu-Zn superoxide dismutase (SOD1) are associated with the familial form of amyotrophic lateral sclerosis (ALS), a disorder affecting the integrity of motor neurons in the brain and spinal cord and leading to paralysis and death, usually within 5 years. While health care providers can do a great deal to ease the discomfort and anxiety experienced by ALS patients, there is no known cure. The SOD1-linked sub-set of the disease offers the best chance of understanding its origin and arriving at a general strategy for a cure. Current research strongly suggests that the gain of a toxic property by this otherwise essential enzyme is the cause of its pathogenic properties. We are pursuing an intensive program that involves both computational and experimental approaches based on structural data. Our main objective is to reveal the common structural factors that make the mutations of the SOD1 molecule so lethal compared to the wild-type enzyme, with the aim of stabilising the structures of pathogenic variants via a structure based lead optimisation programme. The Ph.D. studentship is jointly funded by the University and a small US biotech company. The successful candidate will use a multidisciplinary approach based on X-ray crystallography, Xray scattering and molecular biology methods. The project will be important for the future development of therapeutic remedies for the familial form of the disease and will have wider implications for the more common sporadic motor neuron disease as well as possibly other neurodegenerative disorders such as Parkinson's and Alzheimer's diseases. We are looking for candidates with strong motivation and interest in applying biophysical methods to important biological problems. A background in molecular biology or biochemistry is desirable. Funding Notes Review of applications will begin immediately till a suitable candidate is found. You will need to be a citizen of the European Union. Funding is available for an immediate start.
