A number of ELISA Kits are available that target O3FAR1, an alias of the protein, free fatty acid receptor 4. The human protein, encoded by the gene FFAR4, is a member of the G-protein coupled receptor 1 family. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: BMIQ10, GPR120, GPR129, GT01, O3FAR1, PGR4. Homology is conserved in other species, such as Mouse, Rat.
