Free fatty acid receptor 4

Protein-coding gene in the species Homo sapiens

Free Fatty acid receptor 4 (FFAR4), also termed G-protein coupled receptor 120 (GPR120), is a protein that in humans is encoded by the FFAR4 gene. This gene is located on the long arm of chromosome 10 at position 23.33. G protein-coupled receptors reside on their parent cells' surface membranes, bind any one of the specific set of ligands that they recognize, and thereby are activated to trigger certain responses in their parent cells. FFAR4 is a rhodopsin-like GPR in the broad family of GPRs which in humans are encoded by more than 800 different genes. It is also a member of a small family of structurally and functionally related GPRs that include at least three other free fatty acid receptors (FFARs) viz., FFAR1, FFAR2, and FFAR3. These four FFARs bind and thereby are activated by certain fatty acids.
