Project Z03 – Peptide synthesis and membrane protein (GPCR) expression
The CRC consortium aims to investigate rhodopsin-like peptide-ligand GPCRs or adhesion GPCRs that are activated by peptide segments. The central goal of the Z03 project is to facilitate experimental approaches on the focused GPCRs by providing sufficient amounts of wild-type or chemically modified peptides as well as efficient GPCR-target plasmid construct design, test-expression and stabilization strategies of individual GPCR proteins for projects requiring to work in vitro on the purified samples. Furthermore, standardized approaches and protocols shall be worked out and applied. Z03 will be involved in the training within IRTG.
