Tachykinin precursor
Tachykinin peptides are one of the largest families of neuropeptides, found from amphibians to mammals. They were so named due to their ability to rapidly induce contraction of gut tissue. The tachykinin family is characterized by a common C-terminal sequence, Phe-X-Gly-Leu-Met-NH2, where X is either an Aromatic or an Aliphatic amino acid. The genes that produce tachykinins encode … WebJun 1, 2009 · TAC1 (tachykinin, precursor 1) 2009-06-01 Philip K Lim , Shyam A Patel , Pranela Rameshwar Affiliation ... Each encodes peptides belonging to the tachykinin family of peptides. The major peptides produced from the TAC1 transcripts are substance P and neurokinin A. Others include neuropeptide K, and neuropeptide gamma.

Web(A) Neurokinins are the product of three genes: tachykinin 1 ( TAC1 ), TAC3, and TAC4. The mRNA from these genes is spliced to form precursor proteins, preprotachykinin (PPT) A, B, and C, which are further cleaved by convertases to give the final peptide products. Substance P, neurokinin A, and neurokinin B are the major neurokinins produced.
