PKG Substrate is a selective substrate for cGMP-dependent protein kinase (PKG).
Incorporation of [33P]ATP into the synthetic peptide PKG substrate RKRSRAE is measured. N6-benzyl-ATP inhibits kinase activity of PKG Iα gatekeeper mutants but not WT. The serotonin transporter (SERT) is responsible for reuptake of serotonin (5-hydroxytryptamine) after its exocytotic release from neurons. SERT is regulated by several processes, including a cyclic GMP signaling pathway involving nitric oxide synthase, guanylyl cyclase, and PKG[1].
