Gamma-Preprotachykinin amide (72-92) acetate

Gamma-preprotachykinin amide (72-92) acetate is a 21 amino acid peptide belonging to the tachykinin (TK) family and including neurokinin A (NKA) in its C-terminal sequence. gamma-preprotachykinin amide (72-92) acetate possesses higher affinity than NKA for central NK-2 receptors; it shows lower affinity for NK-1 receptors, however, it potently stimulates salivary secretion, which is mediated by NK-1 receptor activation.
