CD320 Antibody (C-term) Blocking Peptide

Synthetic peptide

Product Information
Primary Accession Q9NPF0
Clone Names 100405029
Peptide ID 100405029
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 Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.
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 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). CD320 augments the proliferation of PC precursors generated by IL-10. Receptor for the cellular uptake of transcobalamin bound cobalamin.
Cellular Location Membrane; Single-pass type I membrane protein
Tissue Location Expressed abundantly on follicular dendritic cells (FDCs).

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]).
