It encodes a glycoprotein secreted by parietal cells of the gastric mucosa and is required for adequate absorption of vitamin B12. Vitamin B12 is necessary for erythrocyte maturation and mutations in this gene may lead to congenital pernicious anemia. [provided by RefSeq, Jul 2008] Annotation information Note: GIF (Gene ID: 2694) and MT3 (Gene ID: 4504) share the GIF symbol/alias in common. GIF is a widely used alternative name for metallothionein 3 (MT3), which can be confused with the official symbol for GIF (gastric intrinsic factor, GeneID 2694).
