Structural and functional analysis of intermediate states during the formation of promiscuous-GPCR-G protein complex
I have used cryo-electron microscopy to determine the structure of the neurotensin receptor (NTSR1), a promiscuous GPCR (i.e., a GPCR capable of activating multiple G proteins), and its intermediate complex formation with Gi. Based on various previous studies, I thought that the observed intermediates might be common to promiscuous GPCRs in general, and in the present study, I analyze the structure of promiscuous GPCRs and G-protein complexes other than NTSR1. In this way, I aim to elucidate the universal rules underlying the complex formation process.


I am very honored to be recognized as an original study. I hope I can continue to make progress so as not to disappoint you.
