26576642 MRAP expression in human cell line results in an ACTH responsive phenotype.
26469516 Data show that co-expression with MRAPalpha, but not MRAP2, enhances MC4R constitutive activity. MRAPalpha-enhanced MC4R constitutive activity is not dependent on MC4R complex glycosylation but may result from MRAPalpha-induced changes in MC4R conformational states.
26424796 The results firmly establish that only the copy of MRAP oriented with the amino terminus on the extracellular side of the receptor is essential for Adrenocorticotropic Hormone signal transduction.
23418361 Data suggest that MRAP regulates expression of melanocortin receptors (MC1R-MC5R); MRAP is highly expressed in both zona fasciculata and undifferentiated zone of adrenal gland, sites of MC2R-mediated adrenal steroidogenesis. [REVIEW]
22419722 MRAP is positively regulated by ACTH and AngII in human adrenocortical tissues.
22366472 The data suggest that MRAPalpha is involved in MC2R targeting to the plasma membrane, while MRAPbeta may enhance ACTH-MC2R coupling to cAMP production.
21951701 A novel MRAP mutation is identified in a neonate where disruption of intron 3 splice-site results in a prematurely terminated translation product causing complete lack of adrenocorticotrophic (ADTH) hormone receptor response.
21195128 ACTH binding to MC2R stimulates PKA-dependent p44/p42(mapk) phosphorylation.
20494980 The MRAP promoter is activated by serum depletion according to promoter reporter assays in HEK 293 cells.
20427498 study shows that novel missense mutations in MRAP are associated with a milder, late onset phenotype in two families with familial glucocorticoid deficiency
