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(biāo)簽:
N-terminal 10xHis-tagged
產(chǎn)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:
Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
儲(chǔ)存條件:
Store at -20°C/-80°C upon receipt, aliquoting is
necessary for
mutiple use. Avoid repeated freeze-thaw cycles.
保質(zhì)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(xiàng):
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Outward rectifying potassium channel. Produces rapidly activating outward rectifier K(+) currents. May function as background potassium channel that sets the resting membrane potential. Channel activity is directly activated by calcium signal. Activated by the G(q)-protein coupled receptor pathway. The calcium signal robustly activates the channel via calcineurin, whereas the anchoring of 14-3-3/YWHAH interferes with the return of the current to the resting state after activation. Inhibited also by arachidonic acid and other naturally occurring unsaturated free fatty acids. Channel activity is also enhanced by volatile anesthetics, such as isoflurane. Appears to be the primary target of hydroxy-alpha-sanshool, an ingredient of Schezuan pepper. May be involved in the somatosensory function with special respect to pain sensation.
基因功能參考文獻(xiàn):
We compared the kinetics of Ba2+ block when channels were phosphorylated (inhibited) or dephosphorylated (activated) and in different mutants mimicking the two functional states. Neither the phosphorylation/dephosphorylation nor the point mutations influenced the development of Ba2+ block, suggesting that conformational changes of the bundle crossing region do not contribute to phosphorylation-dependent gating of TRESK.

single residue of TRESK was found to be glycosylated upon heterologous expression. Signals of the N-glycosylation mutants were reduced by >50% because of inadequate surface expression of the channel. PMID: 20006580
TRESK-2 is a functional member of the K(2P) channel family and contributes to the background K+ conductance in many types of cells [TRESK-2] PMID: 15123670
the PQIVID sequence is a docking site for calcineurin, and its occupancy is required for the calcium-dependent regulation of TRESK PMID: 16569637
we found no difference in resting membrane potential between dorsal root ganglia neurones of TRESK[wild type] and TRESK knockout mice PMID: 17962323
Because 14-3-3 proteins are ubiquitous, they are expected to control the duration of calcineurin-mediated TRESK activation in all the cell types that express the channel, depending on the phosphorylation state of serine 264. PMID: 18397886
