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]
TCN1 (Transcobalamin 1) is a Protein Coding gene. Diseases associated with TCN1 include Transcobalamin I Deficiency and Vitamin B12 Deficiency. Among its related pathways are Innate Immune System and Selenium Micronutrient Network. Gene Ontology (GO) annotations related to this gene include cobalamin binding. An important paralog of this gene is CBLIF.
