8-Br-PET-cGMP

8-Br-PET-cGMP is an agonist of cGMP-dependent protein kinase type I (cGKI). 8-Br-PET-cGMP promotes the dimerization of cGKI and activates its catalytic activity by binding to the regulatory domain of cGKI. 8-Br-PET-cGMP can be used to study the role of cGMP signaling pathways in cell growth, vasodilation, and smooth muscle cell function.
