pkg substrate

PKG Substrate is a selective substrate for cGMP-dependent protein kinase (PKG), showing a strong preference for PKG Iα (Km = 59 µM) over PKG II (Km = 305 µM).

PKG Substrate acetate（81187-14-6 free base) 是 cGMP 依赖性蛋白激酶 (PKG) 的选择性底物。PKG Substrate 是蛋白激酶 G (PKG) 的选择性底物，PKG Iα (Km = 59 µM) 优于 PKG II (Km = 305)微米）。

2-Chloroadenosine 5-triphosphate (2-chloro ATP), an analog of ATP and adenine nucleotide, functions as an antagonist of the purinergic P2Y1 receptor, inhibiting ADP-induced intracellular calcium mobilization in Jurkat cells with a Ki value of 2.3 µM. Additionally, 2-chloro ATP acts as an agonist of purinergic P2X receptors, demonstrated by inducing inward currents in HEK293 cells expressing either human bladder smooth muscle or rat PC12 receptor forms, with EC50 values of 0.5 and 2.5 µM, respectively. It also triggers relaxation in precontracted isolated guinea pig taenia caeci strips in a concentration-dependent fashion. Furthermore, 2-chloro ATP has been employed in research to investigate the substrate specificity of cyclic nucleotide-dependent protein kinases, including protein kinase A (PKA) and PKG.

Competitive inhibitor of cGMP-dependent protein kinase (PKG); analog of a substrate peptide corresponding to a phosphorylation site of histone H2B. Competes with synthetic substrates (Ki = 86 mM) but does not inhibit phosphorylation of intact histones by
