Introduction
GNAQ, also known as Guanine nucleotide-binding protein belong to the G-alpha
family. Guanine nucleotide-binding proteins (G proteins) are involved as
modulators or transducers in a variety of transmembrane signaling systems. GNAQ
regulates B-cell selection and survival and is essential in order to prevent
B-cell-dependent autoimmunity. GNAQ also regulates chemotaxis of BM-derived neutrophils
and dendritic cells, in vitro. GNAQ is an alpha subunit in the Gq class,
couples a seven-transmembrane domain receptor to activation of
phospolipase C-beta. Mutations at this locus have been connected
with problems in platelet activation and aggregation. A related pseudogene to
GNAQ exists on chromosome 2.
Description
GNAQ Human Recombinant produced in E.Coli is a single,
non-glycosylated polypeptide chain containing 382 amino acids (1-359 a.a) and
having a molecular mass of 44.5kDa.
GNAQ is fused to a 23 amino acid His-tag at N-terminus
& purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered clear solution.
Formulation
GNAQ protein solution (0.5mg/ml) containing 20mM Tris-HCl
buffer (pH 8.0), 0.4M UREA and 10% glycerol.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Purity
