Input: The expression of this protein is partly controlled by the binding of NeuroD1 and Par1, and its secretion is inhibited by SIRT4, which ADP-ribosylates glutamate dehydrogenase. Artificial versions of it include Glargine and Lispro versions, and its structure consists of a central zinc ion coordinated to histidine residues in a hexamer. Originally extracted by Banting and Macleod, this hormone partly operates by upregulating the translocation of GLUT4 to the plasma membrane. By up-regulating protein kinase B and PFK-2, this hormone promotes glycogen synthesis and opposes gluconeogenesis. Antagonistic to glucagon, FTP, name this peptide hormone secreted from the beta cells of the Islets of Langerhans, responsible for lowering blood sugar.
