Additional Information
Gene ID 51293
Other Names CD320 antigen, 8D6 antigen, FDC-signaling molecule 8D6, FDC-SM-8D6, Transcobalamin receptor, TCblR, CD320, CD320, 8D6A
Target/Specificity The synthetic peptide sequence used to generate the antibody AP13137b was selected from the C-term region of CD320. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.
Format Peptides are lyophilized in a solid powder format. Peptides can be reconstituted in solution using the appropriate buffer as needed.
StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.
PrecautionsThis product is for research use only. Not for use in diagnostic or therapeutic procedures.
Protein Information
Name CD320
Synonyms 8D6A
Function 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).
Cellular Location Cell membrane; Single-pass type I membrane protein
Tissue Location Detected in the germinal center (GC) of lymphoid follicles (at protein level) (PubMed:11418631). Expressed abundantly on follicular dendritic cells (FDCs) (PubMed:10727470)

Background

The CD320 antigen gene encodes the transcobalamin receptor(TCBLR). Cellular uptake of cobalamin (vitamin B12) is mediated byreceptors expressed on the cell surface. Transcobalamin II (TCN2;MIM 613441), a plasma protein secreted by endothelial cells, bindsthe cobalamin absorbed in the distal ileum and carries 10 to 30% oftotal circulating cobalamin. CD320 encodes a transcobalaminreceptor that binds TCN2-cobalamin at the plasma membrane andinternalizes the complex by endocytosis (Quadros et al., 2009[PubMed 18779389]).
