Previous GeneCards Identifiers for RAMP2 Gene
The protein encoded by this gene is a member of the RAMP family of single-transmembrane-domain proteins, called receptor (calcitonin) activity modifying proteins (RAMPs). RAMPs are type I transmembrane proteins with an extracellular N terminus and a cytoplasmic C terminus. RAMPs are required to transport calcitonin-receptor-like receptor (CRLR) to the plasma membrane. CRLR, a receptor with seven transmembrane domains, can function as either a calcitonin-gene-related peptide (CGRP) receptor or an adrenomedullin receptor, depending on which members of the RAMP family are expressed. In the presence of this (RAMP2) protein, CRLR functions as an adrenomedullin receptor. The RAMP2 protein is involved in core glycosylation and transportation of adrenomedullin receptor to the cell surface. [provided by RefSeq, Jul 2008]
GeneCards Summary for RAMP2 Gene
RAMP2 (Receptor (G Protein-Coupled) Activity Modifying Protein 2) is a Protein Coding gene. Diseases associated with RAMP2 include acute closed-angle glaucoma and pheochromocytoma. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include protein transporter activity and coreceptor activity. An important paralog of this gene is RAMP1.
UniProtKB/Swiss-Prot for RAMP2 Gene
Transports the calcitonin gene-related peptide type 1 receptor (CALCRL) to the plasma membrane. Acts as a receptor for adrenomedullin (AM) together with CALCRL.
Calcitonin and related receptors are a family of G-protein-coupled receptors that comprises of eight subtypes; CT, AMY1, AMY2, AMY3, CALCR, CGRP, AM1 and AM2. The receptors have a wide biological distribution; high concentrations are found in the brain, lung, liver, heart and spleen with lower expression levels present in the testes, gastrointestinal tract and thyroid. The main function of CT receptors is to inhibit bone reabsorption and enhance calcium excretion by the kidneys. AMY receptors are heterodimers of the CT receptor and receptor activating modifying proteins (RAMP) 1-3, which have been implicated in type II diabetes pathology. The CALCRL receptor alone is non-functioning, but forms heterodimers with RAMPs to form the CGRP (CALCRL with RAMP1), AM1 (CALCRL with RAMP2) and AM2 (CALCRL with RAMP3) receptors. Their main function is inducing vasodilation, which causes hypotension.
