G protein-coupled receptors are allosteric proteins that control transmission of external signals to regulate cellular response. Although agonist binding promotes canonical G protein signalling transmitted through conformational changes, G protein-coupled receptors also interact with other proteins. These include other G protein-coupled receptors, other(More)
Amylin is a neuroendocrine hormone involved in glucose regulation. An amylin analog, pramlintide, is used to treat insulin-requiring diabetes. Its anorexigenic actions give it potential as an obesity treatment. There are 3 amylin receptors (AMY1, AMY2, AMY3), comprising the calcitonin receptor and receptor activity-modifying proteins 1, 2, and 3,(More)
Amylin (Amy) receptors are complexes of the calcitonin receptor with receptor activity-modifying proteins. RAMP1 with the calcitonin receptor forms the AMY(1) receptor; the insert negative isoform of the calcitonin receptor in this complex makes the AMY(1(a)) receptor. This receptor has high affinity for Amy and the related peptide calcitonin gene-related(More)
Adrenomedullin (AM) is a peptide hormone with numerous effects in the vascular systems. AM signals through the AM1 and AM2 receptors formed by the obligate heterodimerization of a G protein-coupled receptor, the calcitonin receptor-like receptor (CLR), and receptor activity-modifying proteins 2 and 3 (RAMP2 and RAMP3), respectively. These different CLR-RAMP(More)
The calcitonin receptor (CTR) and calcitonin receptor-like receptor (CLR) are two of the 15 human family B (or Secretin-like) GPCRs. CTR and CLR are of considerable biological interest as their pharmacology is moulded by interactions with receptor activity-modifying proteins. They also have therapeutic relevance for many conditions, such as osteoporosis,(More)
The calcitonin receptor-like receptor (CLR) associates with the accessory protein RAMP1 to form a receptor for the neuropeptide calcitonin gene-related peptide (CGRP). Multiple lines of evidence have implicated CGRP in the pathophysiology of migraine headache making the CGRP receptor an attractive target for development of small-molecule antagonists as a(More)
Receptor activity-modifying proteins (RAMPs) are single pass membrane proteins initially identified by their ability to determine the pharmacology of the calcitonin receptor-like receptor (CLR), a family B G protein-coupled receptor (GPCR). It is now known that RAMPs can interact with a much wider range of GPCRs. This review considers recent developments on(More)
Secretin family G protein-coupled receptors (GPCRs) are important therapeutic targets for migraine, diabetes, bone disorders, inflammatory disorders and cardiovascular disease. They possess a large N-terminal extracellular domain (ECD) known to be the primary ligand-binding determinant. Structural determination of several secretin family GPCR ECDs in(More)
The calcitonin receptor (CTR) is a class B G protein-coupled receptor that is activated by the peptide hormones calcitonin and amylin. Calcitonin regulates bone remodeling through CTR, whereas amylin regulates blood glucose and food intake by activating CTR in complex with receptor activity-modifying proteins (RAMPs). These receptors are targeted clinically(More)
