Histamine-induced internalization of substance P receptors in myoepithelial cells of the guinea pig nasal glands.

abstract：:During a systemic search for peptides that possess the C-terminal amide structure, a novel heptapeptide with isoleucine amide was isolated from bovine serum by sequential steps of reversed phase HPLC. Microsequence and amino acid analyses revealed the structure: Asp-Thr-His-Lys-Ser-Glu-Ile-NH2. Since this peptide has ...
