| Origin of Peptide | CGRP is encoded in the same gene as calcitonin and expressed in neural tissues by processing through a different mRNA pathway | |
| Nature of Peptide/Cargo | Specific binding sites for CGRP have been demonstrated both in the brain and in peripheral target tissues, where CGRP has been shown to act through a CAMP-dependent mechanism | |
| Mechanism | CGRP is encoded in the same gene as calcitonin and expressed in neural tissues by processing through a different mRNA pathway | |
