Description

PE-22-28 is a research peptide derived from the C-terminal fragment of the pituitary adenylyl cyclase-activating polypeptide (PACAP 1–38) and consists of the sequence Gly-Ile-Ala-Gly-Ala-Ser-Asp-Arg. Experimental studies indicate that it modulates neuropeptide signaling via activation of the PAC1 receptor, cAMP accumulation, and the subsequent CREB phosphorylation. PE-22-28 serves as a model compound for investigating synaptic plasticity, neurotrophic modulation, and peptide-mediated neuroprotective mechanisms in preclinical systems.
