Agonist Comments
Other agonists at this receptor include cyclised angiotensin (1-7) [30], angioprotectin [28], angiotensin III and angiotensin IV [23].

Jackson et al. reported that angiotensins I and II activated the MAS1 receptor [27]. However, Dong et al. did not detect responses in MAS1-expressing cells exposed to angiotensins I and II [16]. It was then reported that angiotensin-(1-7), which can be generated from angiotensin II by angiotensin-converting enzyme 2(ACE2) and functions as a vasodilator and antiproliferative agent, binds to Mas-transfected cells and elicits arachidonic acid release [53] and nitric oxide [49]. Angiotensin III and IV can also induce a significant but less pronounced arachidonic acid release [23]. Angiotensin-(1-7) was shown to not activate MAS in G protein coupled receptor functional assays measuring calcium, inositol-1-phosphate and cAMP [5,57,71]. There is very poor pharmacological data including radioligand binding studies that suggest a direct interaction between Ang(1-7) and MAS [24,53,65].

Alamandine, a novel component in renin-angiotensin system (RAS), is reported to act through MrgD, a member of Mas related gene family (Mrg) for which MAS is the founding member [33].

Comments:  Transducer Gi is linked to the effector cAMP inhibition.

MAS is reported to activate G protein constitutively [9,71]. However, no G protein activation by MAS is observed upon stimulation with angiotensin-(1-7) [5,57,71].

MAS is shown to function as a physiological antagonist of AT1R by altering AngII response in different tissues in mice [31,47,61].

Complex vascular effects of Ang(1-7) involving interactions of MAS with AT1R and AT2R are reported in the hearts of MAS knockout mice [10].

MAS upregulates AT1R by constitutive activation of Gαq/11 and subsequent PKC-dependent phosphorylation of AT1R [9].

Trafficking defective AT1R is rescued by co-expression with MAS in CHO and COS7 cells [50].

MAS transformation of cells is mediated by Rac-dependent signaling in NIH 3T3 cells [72].

Expression of Leukemia-associated Rho guanine nucleotide exchange factor (LARG) diminished transforming activity of MAS in NIH 3T3 cells [6].

Gene Expression and Pathophysiology Comments
A recurring translocation site in chromosome 6q that contains MAS1 has been found to be associated with human malignant melanoma [59].
General Comments
MAS1 is a human cellular oncogene [70]. MAS1 is maternally imprinted in foetal mice [60], but not in adult mice [56] and humans [48]. MAS1 is not imprinted in mice [1,35].

Information on miRNAs predicted to target MAS1 3'UTR can be found at TargetScan [21,34].

In humans, the MAS1 receptor is located on chromosome locus 6q24-27, which is also a protooncogene [PMID 3708691]. MAS1 was initially thought to be the GPCR for AngII, but was not accepted on grounds of pharmacology and pattern of tissue expression [3,27,40]. In 2003, Santos et al., proposed that MAS1 is a functional receptor for Ang(1-7) based on the observations that binding sites and in vivo physiological responses to Ang (1-7) is absent in mice harbouring Mas1 deletion [53]. At present, pharmacological support for direct interaction between Ang(1-7) and MAS1 including radioligand binding and/or conventional G protein mediated second messenger generation is weak [5,57,71]. Similar to Ang(1-7), its analogs like A-779, cyclized derivative and non-peptide mimetics (AVE 0991) do not affect MAS1-mediated G protein signaling [30,65]. Conventional G protein signaling by MAS1 was reported upon stimulation with Neuropeptide FF [16] and in response to other peptide and non-peptide ligands, but not by Ang(1-7) [5,57,71]. MAS1 has also been reported to activate G protein signaling and the small GTPase Rac1 signaling constitutively. At cellular level, Ang(1-7) treatment of human messangial cells or MAS1 transfected CHO and COS cells was shown to cause concentration-dependent release of arachidonic acid (AA) by stimulating mitogen activated protein kinase p38.

Deletion of Mas1 gene in mice suggest functional involvement of MAS1 in behavioral processes and in cardiovascular, renal and several metabolic physiologies [11,13,22,26,42,54,63] the MAS1-null mice have increased anxiety, altered heart rate and blood pressure variability. MAS1 knockout mice exhibited impairment in cardiac function associated with profibrotic changes in the expression of extracellular matrix proteins in the hearts. Renal dysfunction and fibrogenic changes in the kidneys were also reported in MAS1 deficient. MAS1 deficient mice were also shown to have increased abdominal fat mass, dyslipidemia, increased levels of insulin and leptin and altered response of adipocytes to insulin. MAS1 deficiency was shown to offer protection from salt induced hypertension and from ischemia/reperfusion injury in both kidney and heart. Endothelial dysfunction resulting in imbalances in nitric oxide (NO) and reactive oxygen species was reported to be a common mechanism behind the MAS1 deficient mice exhibiting alterations in blood pressure and heart rate, and an increase in vascular resistance and decrease in blood flow in the kidney, lung, adrenal gland, mesentry, spleen and brown fat tissues. MAS1 and AT1R may heterooligomerize and result in the altered function and trafficking of AT1R [31,50,61]. Thus, MAS1 may interact with the components of the renin angiotensin receptor implying a role for MAS1 in physiology.

The interaction between Ang(1-7) and MAS1 is perhaps indirect and complex, may involve cross-talk between different proteins or differential expression of genes. However, it is too early to qualify MAS1 as a member of the angiotensin receptor family.
