Summaries for CD320 Gene

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 Omphalocele. Among its related pathways are Diseases of metabolism and Metabolism of water-soluble vitamins and cofactors. GO annotations related to this gene include growth factor activity and cobalamin binding.

UniProtKB/Swiss-Prot for CD320 Gene

  • Receptor for transcobalamin saturated with cobalamin (TCbl) (PubMed:18779389). Plays an important role in cobalamin uptake (PubMed:18779389, PubMed:20524213). Plasma membrane protein that is expressed on follicular dendritic cells (FDC) and mediates interaction with germinal center B cells (PubMed:10727470). Functions as costimulator to promote B cell responses to antigenic stimuli; promotes B cell differentiation and proliferation (PubMed:10727470, PubMed:11418631). Germinal center-B (GC-B) cells differentiate into memory B-cells and plasma cells (PC) through interaction with T-cells and follicular dendritic cells (FDC) (PubMed:11418631). CD320 augments the proliferation of PC precursors generated by IL-10 (PubMed:11418631).
