Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
蛋白標簽：

N-terminal GST-tagged
產品提供形式：

Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

功能：

Receptor for transcobalamin saturated with cobalamin (TCbl). Plays an important role in cobalamin uptake. Plasma membrane protein that is expressed on follicular dendritic cells (FDC) and mediates interaction with germinal center B cells. Functions as costimulator to promote B cell responses to antigenic stimuli; promotes B cell differentiation and proliferation. 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.

1. It has been proposed that the transcobalamin 2 receptor (TCN2R) is associated with idiopathic recurrent spontaneous abortion (RSA). The findings showed no significant association between TCN2R rs2336573 polymorphisms and the risk/protection of recurrent spontaneous abortion. PMID: 29537328
2. the crystal structure of human holo-transcobalamin (TC) in complex with the extracellular domain of CD320, visualizing the structural basis of the TC-CD320 interaction, is reported. PMID: 27411955
3. There was no significant difference in the expression of soluble csf CD320 between patients and controls. PMID: 28486088
4. Although not significant when corrected for multiple testing, eight single nucleotide polymorphisms (SNPs) in two genes, transcobalamin II (TCN2) and the transcobalamin II-receptor (TCblR), were found to influence several clinical traits of cobalamin deficiency. PMID: 25657319
5. The soluble transcobalamin receptor is present in cerebrospinal fluid and correlates to dementia-related biomarkers tau proteins and amyloid-beta. PMID: 26205293
6. Transcobalamin II (TCN2 67A>G and TCN2 776C>G) and transcobalamin II receptor (TCblR 1104C>T) polymorphisms in Korean patients with idiopathic recurrent spontaneous abortion PMID: 24750446
7. The high urinary concentration and the strong correlation between urinary and serum sCD320 suggests that sCD320 is filtered in the kidney. PMID: 24015289
8. Data indicate that only the extracellular region (aa 32-229) of TCblR/CD320 is needed for transcobalamin-cobalamin (TC-Cbl) binding. PMID: 23603833
9. Proliferating cancer cells express measurable levels of TCII and TCII-R. PMID: 24122983
10. TCblr SNP were associated with omphalocele suggests that disruption of methylation reactions, in which folate, vitamin B12, and homocysteine play critical parts, may be a risk factor for omphalocele. PMID: 22116453
11. Our data suggest that variation in TCblR plays a role in neural tube defect risk and that these variants may modulate cobalamin metabolism. PMID: 20577008
12. the cell cycle associated expression of TCblR appears to be tightly regulated in synchrony with the proliferative phase of the cell cycle. PMID: 20627121
13. Analysis of TCblR/CD320, the gene for the receptor for cellular uptake of transcobalamin-bound cobalamin, identified a homozygous single codon deletion, c.262_264GAG (p.E88del), resulting in the loss of a glutamic acid residue. PMID: 20524213
14. Confocal microscopy of tonsil sections revealed co-localization of CD320 with CD19 and CD38 but not with CD3 indicating that germinal center B cells expressed CD320 in addition to follicular dendritic cells. PMID: 19123977
15. This gene encodes a receptor for cellular uptake of transcobalamin-bound vitamin B12. PMID: 18779389
