MRAP2 Antibody, FITC conjugated

1. The accepted idea that melanocortin Receptor Accessory Proteins (MRAPs) are specific regulators of melanocortin receptors was recently challenged by the discovery that MRAP2 inhibits the activity of prokineticin receptors. Recent studies are starting to explain the role of the unusual structure of MRAPs and to illustrate the importance of MRAP2 for the maintenance of both energy and glucose homeostasis. [review] PMID: 28499989
2. In this study we demonstrate a new role of MRAP2 in the regulation of the orexin receptor 1 (OX1R) and identify the specific regions of MRAP2 required for the regulation of OX1R and PKR1. Importantly, like MC4R and PKRs, OX1R is predominately expressed in the brain where it regulates food intake PMID: 28939058
3. This was the first study describing an effect of a MRAP2 mutation on mediated by regulation of the melanocortin-4 receptor FUNCTION IN HUMAN. PMID: 27474872
4. no gene harboring deletions were identified in the SIM1 and MRAP2 regions in the Prader Willi like (PWL) cohort; further functional analysis of p.P352S found in SIM1 and p.A40S found in MRAP2 is useful; this would provide further support for possible role of SIM1 and MRAP2 in the pathogenesis of the PWL phenotype in a limited number of patients PMID: 26795956
5. MC3R is a 2-exon gene that requires a 5' UTR for translation, localization, and potential interaction with MRAP2 PMID: 25051171
6. In a study of humans with severe, early-onset obesity, they found four rare, potentially pathogenic genetic variants in MRAP2, suggesting that the gene may also contribute to body weight regulation in humans. PMID: 23869016
7. Data suggest that MRAP2 regulates expression of melanocortin receptors (MC1R-MC5R); MRAP2 is highly expressed in fetal adrenal glands; MRAP2 is also expressed in hypothalamus, a site that expresses high levels of MC3R and MC4R. [REVIEW] PMID: 23418361
8. MRAP2 is positively regulated by ACTH and AngII in human adrenocortical tissues. PMID: 22419722
9. The MC2R/MRAP2 complex requires much higher concentrations of ACTH to activate compared with the MC2R/MRAP complex. PMID: 21367968
10. MRAP2 is an endogenous inhibitor that competes with MRAP for binding to MC2R and decreases the potency of adrenocorticotropic hormone (ACTH). PMID: 20371771
