Background : G protein-coupled receptor that is activated by a major product of dietary fiber digestion, the short chain fatty acids (SCFAs), and that plays a role in the reg µLation of whole-body energy homeostasis and in intestinal immunity. In omnivorous mammals, the short chain fatty acids acetate, propionate and butyrate are produced primarily by the gut microbiome that metabolizes dietary fibers. SCFAs serve as a source of energy but also act as signaling molec µLes. That G protein-coupled receptor is probably coupled to the pertussis toxin-sensitive, G(i/o)-alpha family of G proteins but also to the Gq family (PubMed : 12496283, PubMed : 12711604, PubMed : 23589301). Its activation res µLts in the formation of inositol 14,5-trisphosphate, the mobilization of intracell µLar calcium, the phosphorylation of the MAPK3/ERK1 and MAPK1/ERK2 kinases and the inhibition of intracell µLar cAMP accum µLation. May play a role in glucose homeostasis by reg µLating the secretion of GLP-1 in response to short-chain fatty acids accum µLating in the intestine. May also reg µLate the production of LEP/Leptin, a hormone acting on the central nervous system to inhibit food intake. Finally, may also reg µLate whole-body energy homeostasis thro µgh adipogenesis reg µLating both differentiation and lipid storage of adipocytes. In parallel to its role in energy homeostasis, may also mediate the activation of the inflammatory and immune responses by SCFA in the intestine, reg µLating the rapid production of chemokines and cytokines. May also play a role in the resolution of the inflammatory response and control chemotaxis in neutrophils. In addition to SCFAs, may also be activated by the extracell µLar lectin FCN1 in a process leading to activation of monocytes and inducing the secretion of interleukin-8/IL-8 in response to the presence of microbes (PubMed : 21037097). Among SCFAs, the fatty acids containing less than 6 carbons, the most potent activators are probably acetate, propionate and butyrate (PubMed : 12496283, PubMed : 12711604). Exhibits a SCFA-independent constitutive G protein-coupled receptor activity (PubMed : 23066016).
