Exendin 4 (1-8) is an 8-amino acid peptide corresponding to the N-terminal fragment of Exendin 4, a GLP-1 receptor agonist derived from the Gila monster (Heloderma suspectum). Lacking the full-length sequence required for receptor activation, this analog serves as a tool to investigate structure-activity relationships and receptor binding domains. It is widely used in biochemistry and drug discovery to explore minimal functional motifs of Exendin 4 and GLP-1 signaling pathways.
