Biochem/physiol Actions

Gly-Pro-Glu is a neuroprotective compound and the N-terminal tripeptide of IGF-1. Gly-Pro-Glu is neuroprotective after central administration in animal models of neurodegenerative processes, such as Huntington’;s, Parkinson’;s, Alzheimer’;s diseases, and varies acute brain injury animal models. The neuroprotective activity is not related to its affinity to glutamate receptor. Findings indicate that GPE mimics insulin-like growth factor I effects on the somatostatin system through a mechanism independent of β-amyloid clearance that involves modulation of calcium and glycogen synthase kinase 3β signaling.

Gly-Pro-Glu (GPE) is a neuroactive peptide and prevents the binding of glutamate to N-methyl-D-aspartate (NMDA) receptor. It positively regulates the potassium-mediated release of acetylcholine from rat cortical slices. Thus, it is involved in the control of brain function. In vitro studies show that this peptide confers neuroprotection to CA1-2 hippocampal neurons against excitotoxic insult.

General description

IGF1 (insulin-like growth factor 1) protein is cleaved into des-N-(1-3)-IGF-1 and an N-terminal Gly-Pro-Glu (GPE tripeptide). It is thought to be an outcome of specific neural processing.
