Functioning and structure of CXCR4/ACKR3/CCR5 oligomeric complexes

Early stage researcher 3 (ESR3) project
Dr. Thierry Durroux, Dr. Sébastien Granier
Host: CNRS 

I- Project proposal:


  1. Analysis of the pharmacological properties of homo/hetero-oligomers of CXCR4/ACKR3/CCR5

  2. Impact of homo- or hetero-oligomerization on CXCR4 structural properties


  1. Pharmacological properties will be investigated using time-resolved FRET- or BRET-based strategies with fluorescent ligands or nanobodies. Binding experiments will be conducted using the Tag-Lite approach (TR-FRET based). Signalling properties will be examined, looking at G protein coupling using G protein BRET biosensors, arrestin association and arrestin-mediated signalling, internalisation and recycling TR-FRET assays.
  2. Structural analysis of the complexes will be performed in collaboration with Gaetan Bellot, a biophysicists. Biochemical strategies (for receptor purification and electronic microscopy will be implemented. Electronic microscopy will be performed to investigate receptor structure

Planned secondments:

Cisbio Bioassays


II – Requirement candidate:

Required diploma: MSc in molecular/biochemical Life Sciences, pharmaceutical sciences or related Life-Science degree.

Required expertise: biochemistry, pharmacology and molecular biology. 

Recommended expertise: bases in molecular biology, biochemistry, cell culture, cell based assays, fluorescence microscopy.

Great way to finish the week off with some #FCS measurements of CXCR4-expressing HEK cells at @UoNLifeSci 🔬 #FluorescenceFriday

Hello everyone!
I am Noemi Karsai and I’m the next in our #ESR introduction series. I’m #ESR11 and I’m originally from Hungary, currently doing my PhD at @UoNLifeSci @COMPARE_UoBUoN, UK.

The transatlantic ECI GPCR symposium #ECIGPCR is about to start, we are ready!! Thanks to the organizers for their excellent job gathering almost 500 people across the globe! @cyclic_Andreas @NicoleAPerry1 @BenderSci @DesislavaNeshe1

Hello 🙂
I am here to continue the series in which all #ESRs are presenting themselves. I am Viviana Marolda and I am in my first year of PhD. I am #ESR13, originally from Italy, and currently, I am working as a PhD student in @CBMSO_CSIC_UAM, at Universidad Autonoma de Madrid.

Hey twitter!
I am @DehanComez. I am taking over the Oncornet account for a while to start a series of all #ESRs writing about themselves and their projects. I am #ESR5, originally from Turkey and right now I am working as a PhD student in @COMPARE_UoBUoN , @UniofNottingham , UK.

New review on #gpcr structural dynamics out in COSB. Great teamwork with the @JanaSelent group. Thanks to @Lundbeckfonden and @novonordiskfond

ONCORNET2.0 is the successor to #ONCORNET. You can see some of the work of ESRs from the first ONCORNET in this special issue of @MolPharmJournal from 2019, with reviews on #CXCR4 and #ACKR3 structure and function:

Hi everyone – we’re on Twitter! ONCORNET2.0 is a #MarieCurie ITN of 16 ESRs across Europe studying #chemokine #GPCRs #CXCR4 and #ACKR3 in cancer. Our projects cover molecular dynamics, medchem, #pharmacology through to translational work. Follow us for updates from our ESRs!
