GPR119

Bottom

Literature Discussion

endocannabinoids

GPR119 is mainly expressed in the pancreas and tissues of the gastrointestinal tract. GPR119 binds to endocannabinoids Anandamide2OGPEA and OEA (Overton et al., 2006).

bulimia

GPR119 is involved in food intake and glucose homeostasis (keeping blood glucose levels within acceptable limits). OEA is actually the strongest endogenous activator of GPR119 and was shown to reduce food intake and weight gain in rodents via PPARα and TRPV1 (Overton et al., 2006).

obesity

endocannabinoids such as OEA bind to GPR119 to increase cAMP (signals high energy/glucose content to a cell), stimulate insulin secretion and cause fat deposition (Overton et al., 2006).

Distribution Summary

GPR119 is predominantly expressed in the pancreas and the gastro-intestinal tract as well as in the brain.
