RAMPs

 Among the many GPCRs discovered, the calcitonin family of receptors comprise of members that regulate a number of physiological processes and are involved in many pathological conditions. Therefore, understanding how these receptors function is a critical question in the field. When Foord and his colleagues discovered that a single transmembrane protein called Receptor Activity Modifying Proteins (RAMPs) could modulate the surface expression of GPCRs of the calcitonin family, it widely opened the field of receptor life cycle. Hundreds of studies have confirmed the importance of RAMPs in the life cycle of this receptor family. Receptor biology is a rapidly expanding field and with the advances in cell and molecular biology and in vivo techniques, it is very likely that the field of RAMPs will explode further and many unanswered questions will be answered with in the next few years.
