Neuropeptide Y (free acid) (human)

<p>Neuropeptide Y (free acid) (human) is a synthetic 36-amino acid peptide representing the full-length human neuropeptide Y (NPY) in its C-terminal free acid form. Unlike the common amidated version, it lacks the C-terminal amidation group. This high-purity variant is a specialized research-grade reagent used to study the effects of this specific post-translational modification on NPY's stability, receptor bind…

1.MECHANISM OF ACTION

This peptide acts as a ligand for the Y-family of G protein-coupled receptors (Y1, Y2, Y4, Y5, Y6). The lack of a C-terminal amide group (free acid form) significantly reduces its receptor binding affinity and biological potency compared to the amidated, native form of NPY. This is because the amide is critical for high-affinity interaction with NPY receptors.

2.PRODUCT INDICATIONS

This product is indicated for specialized research in neuropharmacology, peptide chemistry, and structure-activity relationship (SAR) studies. Key applications include: investigating the role of C-terminal amidation in peptide hormone function and stability, studying the enzymatic processing and degradation pathways of NPY, serving as a precursor or reference compound in the synthesis and characterization of NPY analogs, and as a control in assays comparing the activity of amidated vs. non-amidated NPY forms.

3.CLINICAL EFFICACY OF PRODUCT

Neuropeptide Y (free acid) is a research compound, not a clinical therapeutic. Its efficacy lies in its utility as a precise scientific probe. By comparing the activity of this free acid form to the amidated NPY, researchers can quantify the profound impact of a single post-translational modification on peptide function.
