Entrez Gene Summary for CD320 Gene

  • This gene encodes the transcobalamin receptor that is expressed at the cell surface. It mediates the cellular uptake of transcobalamin bound cobalamin (vitamin B12), and is involved in B-cell proliferation and immunoglobulin secretion. Mutations in this gene are associated with methylmalonic aciduria. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2011]

GeneCards Summary for CD320 Gene

CD320 (CD320 Molecule) is a Protein Coding gene. Diseases associated with CD320 include methylmalonic aciduria due to transcobalamin receptor defect and methylmalonic aciduria and homocystinuria type cble. Among its related pathways are Disease and Metabolism. GO annotations related to this gene include growth factor activity and cobalamin binding.
