α-CGRP is a 37-amino acid neuropeptide and is formed from the alternative splicing of the calcitonin/CGRP gene located on chromosome 11. β-CGRP is less studied. In humans, β-CGRP differs from the α-CGRP by three amino acids and is encoded in a separate gene within the same vicinity.
The CGRP family includes calcitonin (CT), adrenomedullin (AM), and amylin (AMY).
