Research Abstract |
In this KAKENHI project, by employing the newly developed transforming growth factor-alpha (TGFalpha) shedding assay, I screened for G protein-coupled receptors (GPCRs) that respond to bioactive molecules and developed an assay system that can quantify coupling efficiency of heterotrimeric G proteins. I identified three orphan GPCRs (P2Y10, GPR174, A630033H20) as lysophoshadylserine-specific receptors, one GPCR as a lysophoshadylglucoside receptor and two GPCRs as oxidized phospholipid receptors. I generated G protein-deficient HEK293 cells using the CRISPR-Cas9 system and successfully applied them to analyze G protein coupling of GPCRs.
