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, Transient, Due To Transcobalamin Receptor Defect and Methylmalonic Acidemia Due To Transcobalamin Receptor Defect. Among its related pathways are Diseases of metabolism and Metabolism. Gene Ontology (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).
