  ONCOgenic GPCR Network of Excellence and Training


Early stage researcher 9 (ESR9) project - Davide Capoferri

Supervision: Prof G Milligan, Prof G Graham.
Host: UGL (UK) – University of Glasgow, Institutes of i) Molecular Cell and Systems Biology and ii) Infection, Immunity and Inflammation.

I- Project proposal:


1. To determine the impact of β-arrestin/G protein deficiency on CXCR4/ CXCR7, or heteromer function and signalling.

2. To analyze the efficacy of CXCR4 and CXCR7 modulators in G protein and β-arrestin-dependent pathways using label free technologies.

This project will capitalise on the availability, to our group, of a unique cellular resource allowing for conditional, and selective, expression of β-arrestin proteins in HEK cells. These cells will be transfected with CXCR4 and/or CXCR7 and signalling output and hetero/homodimeristion assessed in the presence, or absence, of arrestin expression. Receptor dimerisation will be examined (in the presence or absence of arrestin expression) using FRET-based approaches. These cells will also be used to test the effects of co-expression of CXCR4 and CXCR7 on directional cellular migration using time-lapse migration assays and, again, the dependence of these effects on arrestin signalling will be investigated. If time permits, we will also use these approaches to analyse the β-arrestin dependency of signalling and function in other members of the Atypical Chemokine receptor family. Planned secondments: UAM (ES), Cisbio (FR).

II- Requirement candidate:
Required diploma: MSc degree in a relevant biological science. Candidates with degrees in biochemistry or pharmacology are particularly encouraged to apply.

Required expertise: Biochemistry, molecular biology, cell culture.

Recommended expertise: Chemokine biology, GPCR biochemistry, protein chemistry.
