Gastric inhibitory polypeptide (GIP) is a 42 amino acid hormone secreted by cells of the small intestine which stimulates insulin secretion but only in the presence of glucose, suggesting that it could have a role in the maintenance of plasma glucose levels. The characterization of cDNA clones encoding this hormone indicate that it is derived by proteolytic processing of a 153 amino acid precursor (Takeda et al., 1987). The GIP cDNA hybridized to human DNA fragments and co-segregated with human chromosome 17 in a panel of reduced somatic cell hybrids. Hybridization to DNA from a cell hybrid panel composed of segments of chromosome 17 indicated that the GIP gene was encoded in the 17p11.2-qter region. In situ hybridization to human prometaphase chromosomes confirmed this chromosomal assignment and further localized GIP to 17q21.3-q2Z |
