abstract：:Neuropeptide Y (NPY) is known to bind to at least two types of receptors (Y1 & Y2). One type (Y2) is able to bind and undergo activation by both NPY and its C-terminal fragments with good potency while the other (Y1) requires the full length of NPY for good potency. For most NPY analogs that have been examined, potenc...
