Detection of neuropeptides in vivo and open questions for current and upcoming fluorescent sensors for neuropeptides.

abstract：:The secretin receptor is a member of a large family of G-protein-coupled receptors that recognize polypeptide hormone and/or neuropeptides. Charged, conserved residues might play a key role in their function, either by interacting with the ligand or by stabilizing the receptor structure. Of the four charged amino acid...
