Neuropeptide Y, a 36 amino acid peptide abundantly expressed in the brain, is the most
potent orexigenic factor known to date in mammals. It has been shown to be one of the most
conserved neuropeptides in vertebrate evolution. It seems that neuropeptide Y functions, in
addition to sequence conservation, are also well conserved in fish. In the present study, we
cloned and reported the cDNA sequence coding for tilapia 36 aminoacid neuropeptide Y.
We express the tilapia neuropeptide Y gene in Escherichia coli driven by T7 promoter. The …
