In the heart, muscle contraction is powered by the molecular motor beta-cardiac myosin. Mutations within cardiac myosin are associated with inherited heart disease. Although we have structures of many stages of the myosin contractile cycle there is a paucity of information on how beta-cardiac myosin mutations that cause cardiac dysfunction affect myosin structure and mode of action throughout the different stages of the contractile cycle. This can be tackled by trapping the different functional states influenced by mutation by time-resolved cryo-EM
(1) To express and purify a range of cardiac myosin mutants that influence activity and cause disease.
(2) To use time-resolved cryo-EM to trap different catalytic states of different mutated forms.
(3) To integrate the data to produce a detailed model of myosin force generation and mechanism of action in normal and mutated protein.
Experimental Approach: Robust protocols for protein production will be used to generate different mutants. These will be studied by both conventional cryo-EM and new time-resolved methodologies to trap non-equilibrium states. Full training in all aspects is available and you will be part of a large, dynamic and supportive environment with a focus on protein structure/function studies.
You should hold a first degree equivalent to at least a UK upper-second class honours degree or a MSc degree in a relevant subject.
