Also known as Transcobalamin I, transcobalamin I (vitamin B12 binding protein, R binder family), transcobalamin-1, HC, TCI, TC I, haptocorrin, protein R
Haptocorrin (HC) (also known as transcobalamin-1 (TC-1), or cobalophilin) is a transcobalamin glycoprotein that in humans is encoded by the gene. It is essential to protect the acid-sensitive vitamin B12 from degradation while in the stomach. It is also present in the serum where it binds most circulating vitamin B12, rendering it unavailable for uptake by cells (this is conjectured to be a circulating storage function).
