Receptor for angiotensin 1-7. Acts specifically as a functional antagonist of AGTR1 (angiotensin-2 type 1 receptor), although it up-regulates AGTR1 receptor levels. Positive regulation of AGTR1 levels occurs through activation of the G-proteins GNA11 and GNAQ, and stimulation of the protein kinase C signaling cascade. The antagonist effect on AGTR1 function is probably due to AGTR1 being physically altered by MAS1. The MAS oncogene has a weak focus-inducing activity in transfected NIH 3T3 cells. Belongs to the G-protein coupled receptor 1 family. Note: This description may include information from UniProtKB.
