hH 2 R-G sαS is a fusion protein in wich the G sαS<br />
N-terminus is linked to the C-terminus of human<br />
H 2-receptor (hH 2R) via a hexahistidine (His 6)-Tag.<br />
The H 2R couples to G s-proteins to activate adenylate<br />
cyclase (AC). Among the many responses mediated<br />
by the H 2 R are gastric acid secretion, smooth muscle<br />
relaxation, inotropic and chronotropic effects on heart<br />
muscle, and inhibition of leukocyte function.<br />
G sαS is the short splice variant of the α-subunit of the<br />
heterotrimeric G-protein G s. G s activates the effector<br />
AC. G sαS differs from the long splice variant (G sαL ) by<br />
the absence of a 15-amino acid insert between the<br />
ras-like domain and the α-helical domain. G sαS (cat.#<br />
PR-505) possesses a higher GDP-affi nity than G sαL<br />
(cat.# PR-501).<br />
The fusion protein hH 2 R-G sαS ensures a defi ned 1:1<br />
stoichiometry of the receptor and G sαS subunit.<br />
hH 2R-G sαS and hH 2R-G sαL (cat.# PR-618) exhibit similar<br />
constitutive activity as assessed by the effi cacies of<br />
inverse agonists and partial agonists in the steadystate<br />
GTPase assay.<br />
The fusion protein contains a N-terminal FLAG-Tag ®<br />
for immunological detection.<br />

The histamine H 2 -receptor (H 2 R) belongs to the<br />
superfamily of seven transmembrane domain<br />
(7TM), G-protein-coupled receptors (GPCRs). The<br />
endogenous agonist for the H 2 R is histamine which is<br />
both neurotransmitter and autacoid. The H 2 R couples<br />
to G s -proteins to mediate adenylate cyclase (AC)<br />
activation. In some systems, the H 2 R also couples to<br />
G q -proteins and phospholipase C.<br />
Among the many responses mediated by the H 2 R<br />
are gastric acid secretion, smooth muscle relaxation,<br />
positive ionotropic and chronotropic effects on heart<br />
muscle, and inhibition of leukocyte function.<br />
The rat H 2 R was prepared from Sf9 cells infected with<br />
rat H 2R-encoding baculovirus. In this system, the rat<br />
H 2 R couples to the G sα -like G-proteins of the insect<br />
cells to mediate AC activation.<br />

PR-571 1 ml 300,--<br />
Membrane suspension. Supplied in 75 mM Tris-HCl,<br />
pH 7.4, 12.5 mM MgCl 2 , and 1 mM EDTA.<br />
The anaphylatoxin C5a-receptor (C5aR, CD88)<br />
belongs to the superfamily of seven transmembranedomain<br />
(7TM), G protein-coupled receptors (GPCRs).<br />
In monocytes and granulocytes, activation of C5aR<br />
causes chemotaxis, degranulation, and superoxide<br />
anion production. C5aR is also involved in the<br />
formation of adhesion molecules as well as in the<br />
production of so-called “acute-phase” proteins.<br />
C5aR reconstituted with the G-protein G i α 1 β 1 γ 2 was<br />
prepared from Sf9 cells triple-infected with C5aR-,<br />
G i α 1 -, and Gβ 1 γ 2 -encoding baculoviruses.<br />
C5aR contains a N-terminal FLAG-Tag ® and<br />
a C-terminal hexahistidine (His6)-Tag for<br />
immunochemical detection and protection against<br />
proteolysis.<br />
