General description

Guanosine 5′-[β,γ-imido]triphosphate (GMP-PNP, Gpp(NH)p) is a non-hydrolyzable analog of GTP that binds and irreversibly activates G proteins. Gpp(NH)p is used in a variety of applications that involve GTP binding, including GTP-activation, GTP-inhibition, GTP transport, GTP hydrolysis, and GTP structure stabilization. Since a cycle of GTP binding, hydrolysis, and release is required for the initiation of protein translocation across the endoplasmic reticulum, guanosine 5′-[β,γ-imido]triphosphate is often used in studies of protein synthesis. Gpp(NH)p is used to activate ADP-ribosylation factors and to modulate G proteins involved in cell signaling, protein synthesis and other metabolic processes.

Application

Guanosine 5′-[β,γ-imido]triphosphate trisodium salt hydrate has been used: to study K-RAS interactions with the membrane, for the crystallization of Mycobacterium tuberculosis FtsZ, as a translation initiation inhibitor for the analysis of the 48S pre-initiation complex.
Non-hydrolyzable analog of GTP; the preferred GTP analog to activate ADP-ribosylation factor.

Biochem/physiol Actions

Guanosine 5′-[ß,γ-imido]triphosphate binds and irreversibly activates G proteins. Since a cycle of GTP binding, hydrolysis, and release is required for the initiation of protein translocation across the endoplasmic reticulum, this non-hydrolyzable GTP analog is often used in studies of protein synthesis.

Cannabinoid 1 (CB1) receptors have the ability to change conformation between active (R*) and inactive (R) receptor states. Herein, we further characterize these receptor states using series of saturation radioligand binding studies and their differential displacement binding by various CB1

In higher eukaryotes proteins bearing a signal sequence are translocated across the membrane of the endoplasmic reticulum (ER). The initial events of protein translocation are the binding of the signal sequence by the 54 kDa subunit (SRP54) of the signal

The family of heterotrimeric guanine nucleotide-binding regulatory proteins (G proteins) serves an essential role in transducing receptor-generated signals across the plasma membrane. Recent findings reveal unexpected functional roles for individual G protein subunits. Thus, GTP-binding alpha-subunits and the beta gamma-subunit

We have previously shown that the adrenoceptor agonist norepinephrine (NE) is more potent in eliciting contraction in aortas from 1-month-old Fischer 344 rats than it is in older animals. In the present study, we examined alpha1-adrenoceptor-guanine nucleotide regulatory binding protein

The signal recognition particle (SRP) directs signal sequence specific targeting of ribosomes to the rough endoplasmic reticulum. Displacement of the SRP from the signal sequence of a nascent polypeptide is a guanosine triphosphate (GTP)-dependent reaction mediated by the membrane-bound SRP
