Receptor for calcitonin-gene-related peptide (CGRP) together with RAMP1 and receptor for adrenomedullin together with RAMP2 or RAMP3. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase. Heterodimer of CALCRL and RAMP3 (By similarity). Heterodimer of CALCRL and RAMP1 or CALCRL and RAMP2 (By similarity). Belongs to the G-protein coupled receptor 2 family.
