Our understanding of G protein-coupled receptor (GPCR) function has recently expanded to encompass novel protein interactions that underlie both cell-surface receptor expression and the exhibited phenotype. The most notable examples are those involving receptor activity modifying proteins (RAMPs). RAMP association with the calcitonin (CT) receptor-like receptor (CRLR) traffics this receptor to the cell surface where individual RAMPs dictate the expression of unique phenotypes. A similar function has been ascribed to RAMP interaction with the CT receptor (CTR) gene product. This review examines our current state of knowledge of the mechanisms underlying RAMP function.
