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 />

Membrane suspension. Supplied in 75 mM Tris-HCl,<br />

pH 7.4, 12.5 mM MgCl 2, and 1 mM EDTA.<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 />

human, Recombinant, Sf9<br />

insect cells<br />

Cat. No. Amount Price (€)<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 />
