Bioactivity GIP (3-42), human acts as a glucose-dependent insulinotropic polypeptide (GIP) receptor antagonist, moderating the insulin secreting and metabolic actions of GIP in vivo[1].
Invitro The incretin hormone GIP is rapidly degraded in the circulation by dipeptidyl peptidase IV (DPP IV) forming the N-terminally truncated peptide GIP(3-42)[1].
