Summaries for TCN1 Gene

Entrez Gene Summary for TCN1 Gene

  • This gene encodes a member of the vitamin B12-binding protein family. This family of proteins, alternatively referred to as R binders, is expressed in various tissues and secretions. This protein is a major constituent of secondary granules in neutrophils and facilitates the transport of cobalamin into cells. [provided by RefSeq, Jul 2008]

GeneCards Summary for TCN1 Gene

TCN1 (Transcobalamin I (Vitamin B12 Binding Protein, R Binder Family)) is a Protein Coding gene. Diseases associated with TCN1 include transcobalamin ii deficiency and vitamin metabolic disorder. Among its related pathways are Metabolism and Metabolism of vitamins and cofactors. GO annotations related to this gene include cobalamin binding. An important paralog of this gene is GIF.
