Larazotide (AT-1001) is a synthetic octapeptide with the amino acid sequence Gly-Gly-Val-Leu-Val-Gln-Pro-Gly. It functions as a tight junction regulator, specifically acting as a zonulin antagonist. In laboratory research, it is utilized in in vitro models of epithelial barriers to investigate the biochemical mechanisms regulating paracellular permeability and tight junction assembly.
