NCIt synonyms : MAS1; Angiotensin Receptor; MAS1 Gene Product; MAS1 Protein; Mas-Related G Protein-Coupled Receptor A; MAS Proto-Oncogene;
NCIt definition : Proto-oncogene Mas (325 aa, 37 kDa) is encoded by the human MAS1 gene. This protein
is involved in angiotensin binding and G protein-coupled receptor signaling.;
NCIt note : A product of the MAS1 Gene, an oncogene isolated from DNA of a human epidermoid carcinoma
cell line. Based on its deduced amino acid sequence, the MAS1 gene product contains
7 potential transmembrane domains. The MAS1 protein is, therefore, probably an integral
membrane protein. The structure of the MAS oncogene 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. It
is predicted that it would encode a peptide receptor with mitogenic activity which
would act through the inositol lipid signaling pathways. Expression in Xenopus oocytes
and a transfected mammalian cell line demonstrated that the MAS gene product is a
functional angiotensin receptor. (from OMIM);
