Autophosphorylation of cGMP-dependent protein kinase type II.
Cyclic nucleotides are shown to stimulate the autophosphorylation of type II cGMP-dependent protein kinase (cGK) on multiple sites. Mass spectrometric based analyses, using a quadrupole time-of-flight-mass spectrometry instrument revealed that cGMP stimulated the in vitro phosphorylation of residues Ser110 and Ser114, and, at a slow rate, of Ser126 and Thr109 or Ser117, all located in the autoi...
متن کاملcGMP-dependent protein kinase I mediates the negative inotropic effect of cGMP in the murine myocardium.
To study the role of cGMP-dependent protein kinase I (cGKI) for cardiac contractility, force of contraction (F(c)) was studied in electrically driven heart muscle from wild-type (WT) mice and from conventional and conditional cGKI knockout mice. Both 8-Br-cGMP and 8-pCPT-cGMP reduced Fc in cardiac muscle from juvenile WT but not from juvenile cGKI-null mutants. Similarly, the cGMP analogues red...
متن کاملcGMP-dependent protein kinase mediates stimulation of L-type calcium current by cGMP in rabbit atrial cells.
OBJECTIVES cGMP has been shown to exert both stimulatory and inhibitory effects on cardiac L-type calcium current (I(Ca)). The physiological role of cGMP in regulation of cardiac activity is still controversial. cGMP may be of importance in regulation of I(Ca) in atrial cells. The present study was focused on the role of cGMP in the modulation of I(Ca) in rabbit atrial cells. METHODS Enzymati...
متن کاملType II cGMP‑dependent protein kinase inhibits RhoA activation in gastric cancer cells.
Small GTPase RhoA is a key signaling component regulating cell migration and stress fiber formation. Previous studies have shown that RhoA activity is regulated by protein kinases, such as cAMP‑dependent protein kinase (PKA) and type I cGMP‑dependent protein kinase (PKGI), which phosphorylate the protein. This study was designed to investigate the effect of type II cGMP‑dependent protein kinase...
متن کاملType II cGMP-dependent protein kinase directly inhibits HER2 activation of gastric cancer cells.
Our previous study demonstrated that type II cyclic guanosine monophosphate (cGMP)-dependent protein kinase (PKG II) inhibited epidermal growth factor (EGF)-induced phosphorylation/activation of epidermal growth factor receptor (EGFR). Since human epidermal growth factor receptor 2 (HER2) has a similar molecular structure to EGFR, the present study was designed to investigate whether PKG II als...
