Constructs The human CTRaleu (hCTR), RAMPs and G protein constructs used in the structure study have been previously described 24,25
The protein pellet was analyzed using Pierce BCA Protein Assay kit (Thermofisher) to determine protein concentrations, and the supernatant was transferred into a new tube for the identification of metabolite levels by mass spectrometry analysis at the Metabolomics Expertise Center (MEC - KU Leuven/VIB)
