This enzyme is primarily located in the pancreatic b-cells in the islets of Langerhans, and as such, it has become a target for potential Type II Diabetes treatments (Kebede). Activation of hGPR40 has been shown to both stimulate insulin secretion and decrease glucose concentration (Ma, 2016). GPR40 is a member of a group of homologous GPCRs all located on chromosome 19q13.1 including GPR41, 42, and 43.
