General description
鸟苷′-[β,γ--亚氨基]三磷酸(GMP-PNP, Gpp(NH)p)是GTP不可水解的类似物,可与G蛋白结合,将其不可逆地激活。 Gpp(NH)p可用于涉及GTP结合的各种应用,包括GTP活化、GTP抑制、GTP转运、GTP水解和GTP结构稳定化。由于GTP结合、水解和释放的循环是启动跨内质网的蛋白转移所必需的,因此鸟苷5′-[β,γ-亚氨基]三磷酸通常用于蛋白质合成研究。Gpp(NH)p可用于激活ADP-核糖基化因子并调节参与细胞信号传导、蛋白质合成和其他代谢过程的G蛋白。
Application
GTP的不可水解类似物;用于激活ADP-核糖基化因子的优选GTP类似物。
鸟苷5′-[β,γ-亚氨基]三磷酸三钠盐水合物用于:研究K-RAS与膜的相互作用,结核分枝杆菌FtsZ结晶作为翻译起始抑制剂,分析48S前起始复合体。

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

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

Canonical mRNA translation in eukaryotes begins with the formation of the 43S pre-initiation complex (PIC). Its assembly requires binding of initiator Met-tRNAiMet and several eukaryotic initiation factors (eIFs) to the small ribosomal subunit (40S). Compared to their mammalian hosts, trypanosomatids

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
