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:
Tris-based buffer,50% glycerol
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:
3-7 business days
注意事項:
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Plays a role in T-cell activation and in the adaptive immune response. Regulates the proliferation of activated T-cells. Regulates the release of cytokines and IFNG by activated T-cells. Mediates the response of T-cells toward infected and transformed cells that are characterized by high levels of phosphorylated metabolites, such as isopentenyl pyrophosphate.
基因功能參考文獻:
Microtubule-associated protein 4 (MAP4) controls the dynein-dependent transport of BTN3A1 in response to nucleic acid stimulation, thereby identifying MAP4 as an upstream regulator of BTN3A1. Thus, the depletion of either MAP4 or BTN3A1 impairs cytosolic DNA- or RNA-mediated type I IFN responses. PMID: 27911820
results show that ligand binding to BTN3A1 induces a conformational change within the intracellular domain that involves the JM region and is required for full activation. PMID: 28705810
findings show that changes in the juxtamembrane domain of BTN3A1, but not its transmembrane domain, induce a markedly enhanced or reduced gammadelta T cell reactivity PMID: 28461569
These findings support intracellular sensing of prenyl pyrophosphates by BTN3A1 rather than extracellular presentation. PMID: 26475929
Human gamma-delta T cells are activated by cytosolic interactions of BTN3A1 with soluble phosphoantigens and the cytoskeletal adaptor periplakin. PMID: 25637025
evidence that gene(s) on Chr6 in addition to BTN3A1 are mandatory for PAg-mediated activation of Vgamma9Vdelta2 T cells. PMID: 24890657
Ligand binding to the BTN3A1 B30.2 domain affects residues in the juxtamembrane region, suggesting ligand-induced conformational change. PMID: 25065532
These studies demonstrate that internal sensing of changes in pAg metabolite concentrations by BTN3A1 molecules is a critical step in Vgamma9Vdelta2 T cell detection of infection and tumorigenesis. PMID: 24703779
BTN3A1 represents an antigen-presenting molecule required for the activation of Vgamma9Vdelta2 T cells. PMID: 23872678
investigation of role of CD277 in activation/inactivation of T-lymphocytes: Data indicate that modulation of CD277 interaction (with agonists or blocking antibodies) with T-cell antigen receptor can modulate activation/inactivation of T-lymphocytes. PMID: 22767497
BTN3A1 is necessary for Vgamma9Vdelta2 activation and begin to unravel the extracellular events that occur during stimulation through the Vgamma9Vdelta2 T cell receptor. PMID: 22846996
CD277 triggering is not involved in CD16- or NKp46-induced NK cell activation. PMID: 21918970
Results point to a role for CD277 up-regulated by microenvironmental signals in the acquisition of a regulatory phenotype by ovarian tumor-associated myeloid cells. PMID: 21113407
