1.MECHANISM OF ACTION

[Tyr22] GIP (22-42), human represents a site-specifically modified fragment of the human GIP hormone. The tyrosine residue at position 22 may serve as a functional handle for conjugation, labeling, or detection purposes, while potentially maintaining or altering the peptide's interaction with GIP receptors or antibodies. This peptide can be used to study the role of specific amino acid residues in receptor binding affinity, signal transduction, or antibody recognition. The modification allows researchers to investigate how single amino acid changes affect biological activity, making it valuable for structure-function relationship studies, epitope mapping, and the development of modified peptides for research or diagnostic applications.
