Binding of 125I-gastrin to porcine gastric transferrin has been demonstrated by covalent cross-linking with disuccinimidyl suberate. The concentration of gastrin required to reduce cross-linking by 50% was approx. 100 microM. The occurrence of both gastrin and gastric transferrin in porcine gastric mucosa and lumen suggests a novel synergistic role for the observed interaction in the uptake of dietary iron.
