Dissecting the neuronal signalling of Tousled-like kinase 2, a gene linked with intellectual disability.
About the Project
Lead supervisor:Dr G Evans
Co-supervisors:Dr Ines Hahn
The student will be registered with the Department of Biology
The challenges of the developing human brain include co-ordinating the birth and migration of 100 billion neurons and the formation of their 1000 trillion synaptic connections. Mutations in genes that regulate these processes are implicated in neurodevelopmental disorders, such as intellectual disability. One such gene, Tousled-like kinase 2 (TLK2), is inextricably linked with human disease. As a cell cycle regulator, TLK2 is frequently amplified and promotes tumour growth in many cancers. Conversely, loss of TLK2 expression or activity causes a rare neurodevelopmental disorder, MRD57, characterised by various nervous system abnormalities, including intellectual disability. We recently discovered that TLK2 shuttles from the nucleus to the cytoplasm during neuronal development, suggesting that TLK2 has neuronal-specific non-nuclear functions in neurons and that its localisation can be regulated dynamically. This project will draw on expertise in kinase signalling, neuronal cell biology, omics screening and live cell imaging in the Evans and Hahn labs to discover the neuronal functions of TLK2 and gain mechanistic insight into how loss of neuronal TLK2 might lead to the phenotypes of MRD57. You will join a thriving neuroscience community and training will be provided in a wide range of neuronal cell biology, protein biochemistry and imaging approaches.
