In this project, we will investigate how the SMC complex ‘Cohesin’ fulfils a second important role by building interphase chromatin architectural features, including chromatin loops and topologically associating domains. Widely recognised as contributing to genome organisation and transcriptional control, the mechanism by which cohesin shapes the interphase genome remains incompletely understood.
This project will use chemical biology and genomics tool development to visualise the real-time behaviour of Cohesin while it builds interphase chromatin architectural features. The outcome will inform our understanding not only of Cohesin function, but also of how the wider family of SMC complexes act in genome organisation and stability.
Below you can find a recent review on the subject [1], as well as research publications from the last four PhD students who graduated from our laboratory [2-5].
Candidate background
This project requires a strong interest in molecular mechanisms that underpin fundamental cellular processes, in this case chromatin organisation in the cell nucleus. A background in, and experience with, genomics techniques and computational data analysis will be an advantage. Projects might also use biochemical, structural, and biophysical approaches.
Lab-specific question
Why would you like to join the Chromosome Segregation Laboratory, and how does your past experience prepare you for joining us.
Funding Notes
Successful applicants will be awarded a non-taxable annual stipend of £27,715 plus payment of university tuition fees. Students of all nationalities are eligible to apply.
