Human Polyclonal RAMP2 Primary Antibody pour IF (p), IHC (p) - ABIN1386641
Qiao, Wang, Wang, Zhao, Zhang, Han, Peng: Intermedin is upregulated and attenuates renal fibrosis by inhibition of oxidative stress in rats with unilateral ureteral obstruction. dans Nephrology (Carlton, Vic.) 2015
the cardiovascular response of Ramp1(-/-), Ramp2(+/-), Ramp3(-/-), Ramp1(-/-)/Ramp3(-/-) double-knockout (dKO), and Calcrl(+/-) mice to AM and CGRP were compared to wildtype mice.These results suggest that the hypotensive effect of AM is primarily mediated through the CLR/RAMP1 heterodimer, but that AM signaling via CLR/RAMP2 and CLR/RAMP3 also contributes to some hypotensive action.
The AM-RAMP2 system exerts crucial vasoprotective effects after vascular injury and could be a therapeutic target for the treatment of vascular diseases.
Results provide in vivo evidence of a role for RAMP2 in placental development distinct from the RAMP2-calcitonin receptor-like receptor/adrenomedullin signaling paradigm; decreases Pthr1 expression and causes a blunted response to systemic parathyroid hormone; and identify additional pathways underlying the endocrine and fertility defects of the previously characterized Ramp2 heterozygous adult females.
the Adrenomedullin-RAMP2 system regulates vascular integrity, whereas RAMP2 deletion promotes vascular permeability
RAMP2 is essential for early vascular development and knockout-mice die in utero.
These results indicate the AM-RAMP2 system works to protect nerve cells from both acute and chronic cerebral ischemia by maintaining cerebral blood flow suppressing oxidative stress, and in the case of chronic ischemia, enhancing capillary growth.
It is not only an angiogenesis factor, but maintains hemostasis of blood vessels and organs.
The AM-RAMP2 system is a key determinant of vascular integrity and homeostasis from prenatal stages through adulthood.
These data demonstrate that the adrenomedullin-RAMP2 system is essential for cardiac metabolism and homeostasis.
Data show that mechanical ventilation reduced the expression of receptor activity-modifying protein RAMP3, but not of intermedin (IMD), calcitonin receptor-like receptor (CRLR), and RAMP1 and RAMP2.
Adrenomedullin-RAMP2 system is the potential target for the induction of liver sinusoidal endothelial cells.
this work reveals an essential role for RAMP2 in endocrine physiology and provides the first in vivo evidence for a physiological role of RAMP2 beyond that of AM/CLR signaling

expressed in osteoclast-like cells
RAMP2 plays a key role in the sensitivity and potency of AM-induced hypotensive responses via the AM1 receptor.
RAMP2 and RAMP3 have distinct physiological functions throughout embryogenesis, adulthood, and old age
RAMP2 is a key determinant of the effects of AM on the vasculature and is essential for angiogenesis and vascular integrity.
the vascular smooth muscle AM1 receptor RAMP2 acts at a local level to protect against hypertension-induced vascular hypertrophy and inflammation
Single nucleotide polymorphism of RAMP2 is associated with Stroke.
This work suggests that RAMP2 may modify the agonist activity and trafficking of the GCGR, with potential relevance to production of new peptide analogs with selective agonist activities.
Data suggest that a single GlcNAc residue at CTR N130 (asparagine 130) is responsible for enhanced affinity of calcitonin for CTR ECD; the same appears to apply for enhanced affinity of amylin for RAMP2-CTR ECD. [GlcNAc = N-acetylglucosamine; CTR = calcitonin receptor; ECD = extracellular domain; RAMP2 = receptor (calcitonin) activity modifying protein 2].
interaction of RAMP2 or RAMP3 with CLR induces conformational variation in the juxtamembrane region, yielding distinct binding pockets, probably via an allosteric mechanism.
This study reveals the glucagon receptor as a previously unidentified target for GLP-1 receptor agonists and highlights a role for RAMP2 in regulating its pharmacology.
Data suggest that ligand binding of a G protein-coupled receptor (GPCR) may inform drug development targeting calcitonin receptor-like receptor (CLR):receptor activity-modifying proteins RAMP1/2 complexes.
the AM system is widely expressed in human thymus from newborns; both AM1 receptor components CLR and RAMP2, but not RAMP3, are not associated with the plasma membrane of TECs and thymocytes but are located intracellularly, notably in the nucleus
Adrenomedullin-RAMP2 system suppresses ER stress-induced tubule cell death and is involved in kidney protection.
Data suggest isoforms of RAMP modulate accessibility of peptides to residues situated on CALCRL (calcitonin receptor-like receptor) N-terminal domain; RAMP3/RAMP2/RAMP1 appear to alter accessibility of specific residues at CALCRL-RAMP interface.
RAMP2 gene expression increases with gestational age development in the fetal lung.
The CRLR-RAMP2 interactions were confirmed for the full-length proteins on the cell surface by site-specific photo-crosslinking.
the hCRLR C-tail is crucial for adrenomedullin-evoked cAMP production and internalization of the CRLR/RAMP2, while the receptor internalization is dependent on the aforementioned GPCR kinases, but not Gs coupling.

Co-expression of calcitonin receptors (CT) lacking a portion of domain 1 with receptor activity-modifying protein (RAMP) 1, 2, or 3 appears to produce functional CT-(8-32)-sensitive adrenomedullin receptors.
TNF-alpha induced time- and dose-dependent decreases in the expression of RAMP2 mRNA in cultured human coronary artery smooth muscle cells , thereby diminishing AM-evoked cAMP production
Data found that expressions of RAMP1, RAMP2 and RAMP3 mRNAs increased with the worsening of heart function, but the expressions of RAMP1 and RAMP2 mRNA decreased at level IV of heart failure.
adrenomedullin receptors are comprised of RAMP2 and calcitonin receptor-like receptor.
the respective C-tails of hRAMP2 and -3 differentially affect hCRLR surface delivery and internalization
This study reveals important functionality of the RAMP C-terminal domain and identifies key differences in the role of the RAMP C terminus for calcitonin receptor versus calcitonin receptor-like receptor-based receptors.
RAMP2 is silenced by promoter hypermethylation in lung cancer
Data indicate that adrenomedullin mRNA and protein signal were only found in trophoblast binucleate cells (BNCs), whereas those of CRLR, RAMP2 and RAMP3 were detected in cotyledonary villous and caruncular epithelial cells.
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.
