Template:STRUCTURE 2bb5

Structure of Human Transcobalamin in complex with Cobalamin

Template:ABSTRACT PUBMED 16537422

Disease

[TCO2_HUMAN] Defects in TCN2 are the cause of transcobalamin II deficiency (TCN2 deficiency) [MIM:275350]. This results in various forms of anemia.

Function

[TCO2_HUMAN] Primary vitamin B12-binding and transport protein. Delivers cobalamin to cells.
