Intrinsic factor. Intrinsic factor (IF), also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of vitamin B12 (cobalamin) later on in the small intestine. In humans, the gastric intrinsic factor protein is encoded by the GIF gene.
When the stomach does not make enough intrinsic factor, the intestine cannot properly absorb vitamin B12. Common causes of pernicious anemia include: 1  Weakened stomach lining (atrophic gastritis). 2  An autoimmune condition in which the body's immune system attacks intrinsic factor protein or the cells that make it.hen the stomach does not make enough intrinsic factor, the intestine cannot properly absorb vitamin B12.
