CGRP1/CALCA is a peptide hormone that induces vasodilation mediated by the CALCRL-RAMP1 receptor complex. Dilates a variety of vessels including the coronary, cerebral and systemic vasculature. Its abundance in the CNS also points toward a neurotransmitter or neuromodulator role. It also elevates platelet cAMP. CGRP1 can also bind and activate CALCR-RAMP1 (AMYR1) receptor complex.
Belongs to the calcitonin family.
Detected in nerve cells of cerebrum, hippocampus and pons/midbrain in newborns, and only in nerve cells of pons/midbrain in adult.
