| 摘要 |
Novel gastric inhibitory peptide (GIP) polypeptide compositions are provided. Human GIP alleles encode an extended peptide, referred to herein as GIP55S or GIP55G, which is resistant to serum degradation, relative to the known mature GIP peptide. GIP55S or GIP55G peptides find use where it is desirable to modulate insulin secretion. |
