Claim: CALCRL associated with RAMP1, it is a heterodimer protein and its sequence reveals multiple hydrophobic and hydrophilic regions.
Evidence: CALCRL associated with RAMP1 produces the CGRP receptor which is a trans-membrane protein receptor that is made up of four chains. It is a heterodimer protein composed of two polypeptide chains differing in composition of their amino acid residues. The sequence reveals multiple hydrophobic and hydrophilic regions throughout the four chains in the protein.
