Olfactory receptor 51E2 (OR51E2)

Probable G protein-coupled receptor that is activated by the short chain fatty acids (SCFA) acetate and propionate. In response to SCFA, may positively regulate renin secretion and increase blood pressure (PubMed:23401498).

Might also be triggered by steroid hormones and regulate cell proliferation (PubMed:19389702). May also be the olfactory receptor being triggered by beta-ionone (PubMed:19389702).
