Abstract

γ-Preprotachykinin mRNA is the most abundant tachykinin mRNA in rat tissues, but the pathway of posttranslational processing of its translation product is unknown. An antiserum was raised against the synthetic peptide Asp-Ala-Gly-His-Gly-Gln-Ile-Ser-His [neuropeptide γ-(1-9)-peptide, equivalent to γ-preprotachykinin-(72-80)-peptide], that showed 70-Arg71 in γ- preprotachykinin is a major site of posttranslational processing, but the resulting product, neuropeptide γ-(1-9)-peptide, is neither an agonist nor an antagonist at the neurokinin-2 (NK-2) receptor.
