- Abstract
Pancreatic polypeptide and neuropeptide Y share 50% amino acid homology (18 out of 36 residues), suggesting that they may have common ancestral origins. cDNA clones complementary to human mRNAs encoding pancreatic polypeptide and neuropeptide Y were used to detect specific human genomic DNA sequences in human-mouse somatic cell hybrid lines. The pancreatic polypeptide gene (PPY) segregated with human chromosome 17, while the neuropeptide Y gene (NPY) segregated with human chromosome 7. Examination of cell hybrids with chromosomal rearrangements assigned PPY to the p11.1-qter region and NPY to the pter-q22 region of their respective chromosomes.
