MAS proto-oncogene, or MAS1 proto-oncogene, G protein-coupled receptor (MRGA, MAS, MGRA""), is a protein that in humans is encoded by the MAS1 gene. [5] The structure of the MAS1 product indicates that it belongs to the class of receptors that are coupled to GTP-binding proteins and share a conserved structural motif, which is described as a '7-transmembrane segment' following the prediction that these hydrophobic segments form membrane-spanning alpha-helices. The MAS1 protein may be a receptor that, when activated, modulates a critical component in a growth-regulating pathway to bring about oncogenic effects. [5]
Agonists of the receptor include angiotensin-(1-7). Antagonist include A-779 (angiotensin-1-7 with c-terminal proline substituted for D-Ala), or D-Pro (angiotensin-1-7 with c-terminal proline submitted for D-proline).
Mas1 proto-oncogene (MAS1, MGRA) is not to be confused with the MAS-related G-protein coupled receptor, a recently believed to be activated by the ligand alamandine (generated by catalysis of Ang A via ACE2 or directly from Ang-(1-7)).
GTPase HRas, from "Harvey Rat sarcoma virus", also known as transforming protein p21 is an enzyme that in humans is encoded by the HRAS gene. The HRAS gene is located on the short (p) arm of chromosome 11 at position 15.5, from base pair 522,241 to base pair 525,549. HRas is a small G protein in the Ras subfamily of the Ras superfamily of small GTPases. Once bound to Guanosine triphosphate, H-Ras will activate a Raf kinase like c-Raf, the next step in the MAPK/ERK pathway.
Growth factor receptor-bound protein 7, also known as GRB7, is a protein that in humans is encoded by the GRB7 gene.
INT-2 proto-oncogene protein also known as FGF-3 is a protein that in humans is encoded by the FGF3 gene.
The RETproto-oncogene encodes a receptor tyrosine kinase for members of the glial cell line-derived neurotrophic factor (GDNF) family of extracellular signalling molecules. RET loss of function mutations are associated with the development of Hirschsprung's disease, while gain of function mutations are associated with the development of various types of human cancer, including medullary thyroid carcinoma, multiple endocrine neoplasias type 2A and 2B, pheochromocytoma and parathyroid hyperplasia.
The MAS1 oncogene is a G protein-coupled receptor which binds the angiotensin II metabolite angiotensin (1-7). The MAS1 receptor, when activated by binding angiotensin-(1-7), opposes many of the effects of the angiotensin II receptor. Hence, MAS1 receptor agonists have similar therapeutic effects to angiotensin II receptor antagonists, including lowering of blood pressure.
GRB2-associated-binding protein 1 is a protein that in humans is encoded by the GAB1 gene.
Proto-oncogene Wnt-1, or Proto-oncogene Int-1 homolog is a protein that in humans is encoded by the WNT1 gene.
GDNF family receptor alpha-1 (GFRα1), also known as the GDNF receptor, is a protein that in humans is encoded by the GFRA1 gene.
Thyroid hormone receptor alpha (TR-alpha) also known as nuclear receptor subfamily 1, group A, member 1 (NR1A1), is a nuclear receptor protein that in humans is encoded by the THRA gene.
Mas-related G-protein coupled receptor member D is a protein that in humans is encoded by the MRGPRD gene.
Mas-related G-protein coupled receptor MRG is a protein that in humans is encoded by the MAS1L gene.
Proto-oncogene tyrosine-protein kinase Yes is a non-receptor tyrosine kinase that in humans is encoded by the YES1 gene.
Macrophage-stimulating protein receptor is a protein that in humans is encoded by the MST1R gene. MST1R is also known as RON kinase, named after the French city in which it was discovered. It is related to the c-MET receptor tyrosine kinase.
60S ribosomal protein L7a is a protein that in humans is encoded by the RPL7A gene.
T-cell leukemia homeobox protein 1 is a protein that in humans is encoded by the TLX1 gene, which was initially named HOX11.
Proto-oncogene tyrosine-protein kinase ROS is an enzyme that in humans is encoded by the ROS1 gene.
Ubiquitin specific protease 4 (USP4) is an enzyme that cleaves ubiquitin from a number of protein substrates. Prior to the standardization of nomenclature USP4 was known as UNP, and was one of the first deubiquitinating enzymes to be identified in mammals. In the mouse and human the USP4 protein is encoded by a gene containing 22 exons.

Angiotensin (1-7) is an active heptapeptide of the renin–angiotensin system (RAS).
