Tirzepatide is a synthetic 39 amino acid peptide that is lipidated with a C20 fatty diacid moiety via a linker on a lysine residue. It functions as a dual agonist at the glucose dependent insulinotropic polypeptide receptor (GIPR) and the glucagon like peptide 1 receptor (GLP 1R), producing cAMP mediated signaling in receptor expressing assay systems. Tirzepatide is used in receptor pharmacology and cell signaling research investigating incretin GPCR activation, biased signaling, and downstream transcriptional responses in experimental models.
