VFLLANIILAFLFFGF 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(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.
Cationic channel with similar permeabilities for Na(+) and K(+), that is activated by an increase of the proton concentration on the extracellular side. Displays no permeability for chloride ions. Shows slow kinetics of activation, no desensitization and a single channel conductance of 8 pS. Might contribute to adaptation to external pH change.
基因功能參考文獻(xiàn):
Data suggest that neurosteroids bind to two sites per GLIC subunit, both within the transmembrane domain; one site is an intrasubunit site, and the other is located in the interface between subunits. The neurosteroids ligands used in this study were derivatives of 3alpha-hydroxypregnane and tetrahydrodeoxycorticosterone. PMID: 29301936
Here we delineate protein motions underlying Gloeobacter violaceus ligand-gated ion channel gating in a membrane environment and report the interface conformation in the closed and the desensitized states. PMID: 24338475
X-ray structure of a bacterial ligand-gated ion channel with ketamine bound to an intersubunit cavity that partially overlaps with the homologous antagonist-binding site. PMID: 22958642
The overall findings show that His-235 in the transmembrane region of GLIC is a novel proton binding site linked to channel activation. PMID: 22084238
