General Comments
The product of the CALCRL gene, the calcitonin receptor-like receptor alone does not create a functional receptor. Coexpression with receptor activity modifying proteins (RAMPs) allows receptor signal transduction to occur. Reviewed in [1].
Calcitonin receptor-like receptor and RAMP1 make up the CGRP receptor.
Calcitonin receptor-like receptor and RAMP2 make up the AM1 receptor.
Calcitonin receptor-like receptor and RAMP3 make up the AM2 receptor.
The most commonly used abbreviation for this receptor is CLR [1]. At the most recent of the international meetings on CGRP, calcitonin, amylin and adrenomedullin (7th International meeting, 2010), the participants agreed that this should be the preferred abbreviation.
The presence of CLR mRNA does not explain the phenotype of the receptor that is expressed. The expression of RAMP accessory proteins must also be considered.
