The receptor activity-modifying protein 2 (RAMP2) gene is mapped to human chromosome 17q21.2. RAMPs 1-3 are a novel class of single transmembrane accessory proteins. While mammalian RAMPs 1-3 significantly differ in sequence homology and tissue distribution, they possess comparable structure, with a long extracellular N-terminus, a single transmembrane domain, and a short cytoplasmic C-terminus.
Specificity
Anti-RAMP2 (N-terminal) specifically recognizes human RAMP2.
Immunogen
synthetic peptide corresponding to a sequence located near the N-terminal of human RAMP2, conjugated to KLH
application
Anti-RAMP2 (N-terminal) antibody produced in rabbit is suitable for immunoblotting.
Biochem/physiol Actions
Receptor activity-modifying proteins (RAMPs 1-3) are essential for the function of various G-protein coupled receptors (GPCRs). Preferential adrenomedullin (AM) binding is established by the interaction between calcitonin receptor-like receptor (CLR or CRLR) and RAMP2. Tissue-specific analysis of the human and mouse transcriptomes shows that the formation of a functional AM receptors is possible with most CLR being complexed with RAMP2. RAMP2 is required for the transport of AM receptor and for presenting it at the cell surface as a mature glycoprotein. RAMP2 is essential for angiogenesis and vascular integrity, and for lymphatic vascular development during embryogenesis. RAMPs represent as potential targets for the treatment of human diseases related to either AM or calcitonin gene-related peptide (CGRP) physiology.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Storage and Stability
For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers,is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

Adrenomedullin (AM) is a peptide involved both in the pathogenesis of cardiovascular diseases and in circulatory homeostasis. The high-affinity AM receptor is composed of receptor activity-modifying protein 2 or 3 (RAMP2 or -3) and the GPCR calcitonin receptor-like receptor. Testing

The lymphatic vascular system mediates fluid homeostasis, immune defense, and tumor metastasis. Only a handful of genes are known to affect the development of the lymphatic vasculature, and even fewer represent therapeutic targets for lymphatic diseases. Adrenomedullin (AM) is a
Adrenomedullin (AM) is a 52-amino-acid multifunctional peptide that circulates in the plasma in the low picomolar range and can exert a multitude of biological effects through an autocrine/paracrine mode of action. The mechanism by which AM transduces its signal represents

Susumu Ohno's idea that modern vertebrates are degenerate polyploids (concept referred as 2R hypothesis) has been the subject of intense debate for past four decades. It was proposed that intra-genomic synteny regions (paralogons) in human genome are remains of ancient

Receptor activity-modifying proteins (RAMPs) enable calcitonin receptor-like receptor (CRLR) to function as a calcitonin gene-related peptide receptor (CRLR/RAMP1) or an adrenomedullin (AM) receptor (CRLR/RAMP2 or -3). Here we investigated the functions of the cytoplasmic C-terminal tails (C-tails) of human RAMP1
