The cloning and characterization of the human transcobalamin II gene
15 May 1995
Abstract excerpt
Transcobalamin II (TCII) is a plasma protein that binds vitamin B12 (cobalamin; Cbl) and facilitates the cellular uptake of the vitamin by receptor-mediated endocytosis. In genetic disorders that are characterized by congenital deficiency of TCII, intracellular Cbl deficiency occurs, resulting in an early onset of megaloblastic anemia that is sometimes accompanied by a neurologic disorder. To define the genetic...
