(Tyr27)-alpha-CGRP (27-37) (canine, mouse, rat) features a tyrosine substitution that alters receptor-binding specificity within the CGRP family of peptides. This modification enhances the peptide's stability and selectivity for specific CGRP receptors. Researchers use it to study vasodilation mechanisms, pain pathways, and the role of CGRP in the nervous system across species.
