The Dossier

Research Notes

GLP3-R is the house designation for a synthetic, acylated triple-agonist peptide of the incretin family — a single engineered sequence that engages three receptor pathways at once: the glucose-dependent insulinotropic polypeptide receptor, the glucagon-like peptide-1 receptor, and the glucagon receptor.

Research interest centers on how one molecule balances activity across three related class-B receptors, and on how that balance reads against single- and dual-agonist reference peptides. It is offered strictly as a laboratory reference compound.

Research Focus

  • Triple incretin-axis (GIP / GLP-1 / glucagon) receptor pharmacology
  • Energy-balance and satiety-signaling models
  • Glycemic-handling and insulin-signaling models
  • Hepatic lipid-metabolism models
  • Comparative potency against single- and dual-agonist references

Mechanism

GLP3-R is characterized as an agonist at three class-B G-protein-coupled receptors — GIPR, GLP-1R, and GCGR — each coupling principally through Gs, adenylyl cyclase, cAMP, and PKA. Adding the glucagon axis to the two incretin axes is what defines the class, and the balance struck between the three is the property the literature examines.

As with the dual agonists, fatty-acid acylation confers albumin binding and an extended circulating profile relative to the native peptides the sequence is modeled on.

Storage & Handling

Store the lyophilized peptide at −20°C, desiccated and protected from light; −80°C for the longest terms. Reconstituted solution is aliquoted, held at 2–8°C, and used within a short window; avoid repeated freeze-thaw.
