Atrial natriuretic peptide-stimulated Ca2+ reabsorption in rabbit kidney requires membrane-targeted, cGMP-dependent protein kinase type II. (1/31)

Atrial natriuretic peptide (ANP) and nitric oxide (NO) are key regulators of ion and water transport in the kidney. Here, we report that these cGMP-elevating hormones stimulate Ca2+ reabsorption via a novel mechanism specifically involving type II cGMP-dependent protein kinase (cGK II). ANP and the NO donor, sodium nitroprusside (SNP), markedly increased Ca2+ uptake in freshly immunodissected rabbit connecting tubules (CNT) and cortical collecting ducts (CCD). Although readily increasing cGMP, ANP and SNP did not affect Ca2+ and Na+ reabsorption in primary cultures of these segments. Immunoblot analysis demonstrated that cGK II, and not cGK I, was present in freshly isolated CNT and CCD but underwent a complete down-regulation during the primary cell culture. However, upon adenoviral reexpression of cGK II in primary cultures, ANP, SNP, and 8-Br-cGMP readily increased Ca2+ reabsorption. In contrast, no cGMP-dependent effect on electrogenic Na+ transport was observed. The membrane localization of cGK II proved to be crucial for its action, because a nonmyristoylated cGK II mutant that was shown to be localized in the cytosol failed to mediate ANP-stimulated Ca2+ transport. The Ca2+-regulatory function of cGK II appeared isotype-specific because no cGMP-mediated increase in Ca2+ transport was observed after expression of the cytosolic cGK Ibeta or a membrane-bound cGK II/Ibeta chimer. These results demonstrate that ANP- and NO-stimulated Ca2+ reabsorption requires membrane-targeted cGK II.  (+info)

Serine 19 of human 6-pyruvoyltetrahydropterin synthase is phosphorylated by cGMP protein kinase II. (2/31)

6-Pyruvoyltetrahydropterin synthase (PTPS) participates in tetrahydrobiopterin cofactor biosynthesis. We previously identified in a PTPS-deficient patient an inactive PTPS allele with an Arg(16) to Cys codon mutation. Arg(16) is located in the protein surface exposed phosphorylation motif Arg(16)-Arg-Ile-Ser, with Ser(19) as the putative phosphorylation site for serine-threonine protein kinases. Purification of recombinant PTPS-S19A from bacterial cells resulted in an active enzyme (k(cat)/K(m) = 6.4 x 10(3) M(-1) s(-1)), which was similar to wild-type PTPS (k(cat)/K(m) = 4.1 x 10(3) M(-1) s(-1)). In assays with purified enzymes, wild-type but not PTPS-S19A was a specific substrate for the cGMP-dependent protein kinase (cGK) type I and II. Upon expression in COS-1 cells, PTPS-S19A was stable but not phosphorylated and had a reduced activity of approximately 33% in comparison to wild-type PTPS. Extracts from several human cell lines, including brain, contained a kinase that bound to and phosphorylated immobilized wild-type, but not mutant PTPS. Addition of cGMP stimulated phosphotransferase activity 2-fold. Extracts from transfected COS-1 cells overexpressing cGKII stimulated Ser(19) phosphorylation more than 100-fold, but only 4-fold from cGKI overexpressing cells. Moreover, fibroblast extracts from mice lacking cGKII exhibited significantly reduced phosphorylation of PTPS. These results suggest that Ser(19) of human PTPS may be a substrate for cGKII phosphorylation also in vivo, a modification that is essential for normal activity.  (+info)

Nitric oxide and cGMP regulate gene expression in neuronal and glial cells by activating type II cGMP-dependent protein kinase. (3/31)

Nitric oxide (NO) and cGMP have been implicated in many neuronal functions, including regulation of gene expression, but little is known about the downstream targets of NO/cGMP in the nervous system. We found that type II cGMP-dependent protein kinase (G-kinase), which is widely expressed in the brain, mediated NO- and cGMP-induced activation of the fos promoter in cells of neuronal and glial origin; the enzyme was ineffective in regulating gene expression in fibroblast-like cells. The effect of G-kinase II on gene expression did not require calcium uptake but was synergistically enhanced by calcium. G-kinase II was membrane associated and did not translocate to the nucleus; however, a soluble G-kinase II mutant translocated to the nucleus and regulated gene expression in fibroblast-like cells. Soluble G-kinase I also regulates fos promoter activity, but membrane targeting of G-kinase I prevented the enzyme from translocating to the nucleus and regulating transcription in multiple cell types, including glioma cells; this suggests that cell type-specific factor(s) that mediate the transcriptional effects of extranuclear G-kinase II are not regulated by G-kinase I. Our results suggest that G-kinase I and II control gene expression by different mechanisms and that NO effects on neuronal plasticity may involve G-kinase II regulation of gene expression.-Gudi, T., Hong, G. K.-P., Vaandrager, A. B., Lohmann, S. M., Pilz, R. B. Nitric oxide and cGMP regulate gene expression in neuronal and glial cells by activating type II cGMP-dependent protein kinase.  (+info)

The amino-terminal cyclic nucleotide binding site of the type II cGMP-dependent protein kinase is essential for full cyclic nucleotide-dependent activation. (4/31)

For the type I cGMP-dependent protein kinases (cGKIalpha and cGKIbeta), a high affinity interaction exists between the C2 amino group of cGMP and the hydroxyl side chain of a threonine conserved in most cGMP binding sites. To examine the effect of this interaction on ligand binding and kinase activation in the type II isozyme of cGMP-dependent protein kinase (cGKII), alanine was substituted for the conserved threonine or serine. cGKII was found to require the C2 amino group of cGMP and its cognate serine or threonine hydroxyl for efficient cGMP activation. Of the two binding sites, disruption of cGMP-specific binding in the NH(2)-terminal binding site had the greatest effect on cGMP-dependent kinase activation, like cGKI. However, ligand dissociation studies showed that the location of the rapid and slow dissociation sites of cGKII was reversed relative to cGKI. Another set of mutations that prevented cyclic nucleotide binding demonstrated the necessity of the NH(2)-terminal, rapid dissociation binding site for cyclic nucleotide-dependent activation of cGKII. These findings suggest distinct mechanisms of activation for cGKII and cGKI isoforms. Because cGKII mediates the effects of heat-stable enterotoxins via the cystic fibrosis transmembrane regulator Cl(-) channel, these findings define a structural target for drug design.  (+info)

Evidence for the presence of cGMP-dependent protein kinase-II in human distal colon and in T84, the colonic cell line. (5/31)

Heat-stable enterotoxin (STa) stimulates intestinal Cl(-) secretion by activating guanylate cyclase C (GCC) to increase intracellular cyclic GMP (cGMP). In the colon, cGMP action could involve protein kinase (PK) G-II or PKA pathways, depending on the segment and species. In the human colon, both PKG and PKA pathways have been implicated, and, therefore, the present study examined the mechanism of cGMP-mediated Cl(-) transport in primary cultures of human distal colonocytes and in T84, the colonic cell line. Both cell preparations express mRNA for CFTR, Na(+)-K(+)-2Cl(-) cotransporter (NKCC1), GCC and PKG-II as detected by RT-PCR. The effects of STa and the PKG-specific cGMP analogues, 8Br-cGMP and 8pCPT-cGMP, on Cl(-) transport were measured using a halide-sensitive probe. In primary human colonocytes and T84 cells, STa, the cGMP analogues and the cAMP-dependent secretagogue, prostaglandin E(1) (PGE(1)), enhanced Cl(-) transport. The effects of 8Br-cGMP and 8pCPT-cGMP suggested the involvement of PKG, and this was explored further in T84 cells. The effects of 8pCPT-cGMP were dose-dependent and sensitive to the PKG inhibitor, H8 (70 microM), but H8 had no effect on PGE(1)-induced Cl(-) secretion. In contrast, a PKA inhibitor, H7 (50 microM), blocked PGE(1)-mediated but not 8pCPT-cGMP-induced Cl(-) transport. 8pCPT-cGMP enhanced phosphorylation of the PKG-specific substrate, 2A3, by T84 membranes in vitro. This phosphorylation was inhibited by H8. These results strongly suggest that cGMP activates Cl(-) transport through a PKG-II pathway in primary cells and in the T84 cell line of the human colon.  (+info)

Autoinhibition and isoform-specific dominant negative inhibition of the type II cGMP-dependent protein kinase. (6/31)

In the absence of cyclic nucleotides, the cAMP-dependent protein kinase and cGMP-dependent protein kinases (cGKs) suppress phosphotransfer activity at the catalytic cleft by competitive inhibition of substrate binding with a pseudosubstrate sequence within the holoenzyme. The magnitude of inhibition can be diminished by autophosphorylation near this pseudosubstrate sequence. Activation of type I cGK (cGKI) and type II cGK (cGKII) are differentially regulated by their cyclic nucleotide-binding sites. To address the possibility that the distinct activation mechanisms of cGKII and cGKI result from differences in the autophosphorylation of the inhibitory domain, we investigated the effects of autophosphorylation on the kinetics of activation. Unlike the type I cGKs (cGKIalpha and Ibeta), cGKII autophosphorylation did not alter the basal activity, nor the sensitivity of the enzyme to cyclic nucleotide activation. To determine residues responsible for autoinhibition of cGKII, Ala was substituted for basic residues (Lys(122), Arg(118), and Arg(119)) or a hydrophobic residue (Val(125)) within the putative pseudosubstrate domain of cGKII. The integrity of these residues was essential for full cGKII autoinhibition. Furthermore, a cGKII truncation mutant containing this autoinhibitory region demonstrated a nanomolar IC(50) toward a constitutively active form of cGKII. Finally, we present evidence that the dominant negative properties of this truncation mutant are specific to cGKII when compared with cAMP-dependent protein kinase Calpha and cGKIbeta. These findings extend the known differences in the activation mechanisms among cGK isoforms and allow the design of an isoform-specific cGKII inhibitor.  (+info)

Apparent affinity of CFTR for ATP is increased by continuous kinase activity. (7/31)

The cystic fibrosis transmembrane conductance regulator (CFTR) is a chloride channel which is activated by protein phosphorylation and nucleoside triphosphates. We demonstrate here that fusion of the soluble catalytic subunit of cAMP-dependent protein kinase to the membrane protein bacteriorhodopsin yields a constitutively active protein kinase which activates CFTR effectively. As it is membrane-bound it is particularly useful for continuous perfusion of excised inside-out patches. We also tested the effect of a naturally membrane-bound protein kinase, cGMP-dependent protein kinase II, on CFTR. Both kinases, when continuously active, increase apparent affinity of CFTR to ATP about two-fold emphasizing the role of phosphorylation in modulating the interaction of ATP with the nucleotide binding domains.  (+info)

cGMP-dependent protein kinase II modulates mPer1 and mPer2 gene induction and influences phase shifts of the circadian clock. (8/31)

BACKGROUND: In mammals, the master circadian clock that drives many biochemical, physiological, and behavioral rhythms is located in the suprachiasmatic nuclei (SCN) of the hypothalamus. Generation and maintenance of circadian rhythmicity rely on complex interlocked transcriptional/translational feedback loops involving a set of clock genes. Among the molecular components driving the mammalian circadian clock are the Period 1 and 2 (mPer1 and mPer2) genes. Because the periodicity of the clock is not exactly 24 hr, it has to be adjusted periodically. The major stimulus for adjustment (resetting) of the clock is nocturnal light. It evokes activation of signaling pathways in the SCN that ultimately lead to expression of mPer1 and mPer2 genes conveying adjustment of the clock. RESULTS: We show that mice deficient in cGMP-dependent protein kinase II (cGKII, also known as PKGII), despite regular retinal function, are defective in resetting the circadian clock, as assessed by changes in the onset of wheel running activity after a light pulse. At the molecular level, light induction of mPer2 in the SCN is strongly reduced in the early period of the night, whereas mPer1 induction is elevated in cGKII-deficient mice. Additionally, we show that light induction of cfos and light-dependent phosphorylation of CREB at serine 133 are not affected in these animals. CONCLUSIONS: cGKII plays a role in the clock-resetting mechanism. In particular, the ability to delay clock phase is affected in cGKII-deficient mice. It seems that the signaling pathway involving cGKII influences in an opposite manner the light-induced induction of mPer1 and mPer2 genes and thereby influences the direction of a phase shift of the circadian clock.  (+info)

TY - JOUR. T1 - Identification of cGMP-Dependent protein kinase anchoring proteins (GKAPs). AU - Vo, Ngan. AU - Gettemy, Jessica M.. AU - Coghlan, Vincent M.. PY - 1998/5/29. Y1 - 1998/5/29. N2 - To promote both efficiency and selectivity, many protein kinases and phosphatases are maintained in specific subcellular microenvironments through their association with anchoring proteins. In this study, we describe a new class of proteins, called GKAPS, that specifically bind the Type II cGMP-dependent protein kinase (PKG). GKAPs were detected in rat aorta, brain, and intestine using a protein overlay technique. The PKG binding proteins were distinct from AKAPs, proteins known to bind the cAMP-dependent protein kinase (PKA). Furthermore, a synthetic peptide that blocks association of PKA with AKAPs did not affect the PKG-GKAP interaction. Deletion mutagenesis was used to map the GKAP binding determinants within PKG to the N-terminal regulatory region. While most GKAPs were tissue-specific, a ...

CaM-kinase II (CAMK2) is a prominent kinase in the central nervous system that may function in long-term potentiation and neurotransmitter release. Member of the NMDAR signaling complex in excitatory synapses it may regulate NMDAR-dependent potentiation of the AMPAR and synaptic plasticity. Phosphorylates transcription factor FOXO3 on Ser-298 (By similarity). Activates FOXO3 transcriptional activity (PubMed:23805378).
We show that parallel reaction monitoring (PRM) can be used for exact quantification of phosphorylation ratios of proteins using stable-isotope-labeled peptides. We have compared two different PRM approaches on a digest of a U87 cell culture, namely, direct-PRM (tryptic digest measured by PRM without any further sample preparation) and TiO2-PRM (tryptic digest enriched with TiO2 cartridges, followed by PRM measurement); these approaches are compared for the following phosphorylation sites: neuroblast differentiation-associated protein (AHNAK S5480-p), calcium/calmodulin-dependent protein kinase type II subunit delta (CAMK2D T337-p), and epidermal growth factor receptor (EGFR S1166-p). A reproducible percentage of phosphorylation could be determined (CV 6-13%) using direct-PRM or TiO2-PRM. In addition, we tested the approaches in a cell culture experiment in which U87 cells were deprived of serum. As a gold standard we included immune precipitation of EGFR followed by PRM (IP-PRM). For EGFR ...

In addition to vasodilation, NO/NP/cGMP signaling is involved in the development of vasculoproliferative disorders, such as restenosis and atherosclerosis. The analysis of transgenic mice showed that NO can both promote58-64 and inhibit65-70 pathological vascular remodeling (see review5). This finding could explain why NO-generating drugs have not been reported to limit the progression of atherosclerosis in humans. The opposing actions of NO might depend on the magnitude and spatiotemporal profile of its production in a specific pathophysiological setting and are likely mediated through different cellular and molecular mechanisms. A key process in vascular remodeling is the phenotypic modulation of vascular SMCs from contractile to proliferating/dedifferentiated cells.71 It has been reported that NO and cGMP can both promote72,73 and inhibit74,75 the proliferation of cultured SMCs (see reviews12,76). The reason for these contradictory findings and their (patho)physiological significance is not ...
Our previous studies demonstrated that subcutaneous injection of bee venom (BV) into the Zusanli (ST36) acupuncture point, namely BV acupuncture, dose-dependently prevents conditioned place preference (CPP) induced by repeated injection of methamphetamine (METH) in mice. To expand on our observations, the present study was designed to determine the suppressive mechanisms of BV acupuncture in the development of METH-induced CPP by evaluating the changes in expression of ΔFosB, phosphorylated extracellular signal-regulated kinase 1/2 (pERK), and phosphorylated calcium/calmodulin-dependent protein kinase type II (pCaMKII) in the prefrontal cortex (PFC) and nucleus accumbens (NAc) in mice. Pre-emptive treatment with BV at 30 min before repeated METH injection completely suppressed acquisition of CPP at the day 7 test session. METH-induced upregulation of ΔFosB and pERK in PFC and NAc was significantly reduced by BV pretreatment. Expression of pCaMKII was significantly elevated by METH in NAc and ...
The expression and phosphorylation state of VASP was investigated in neutrophils during cell adherence. Adhesion is an essential process for neutrophil migration from the peripheral blood to sites of inflammation. During the process of adhesion, neutrophils adhere and spread without any clear stopping point between these two processes. Therefore, it was important to determine whether VASP was phosphorylated in response to signals involved in adhesion and/or spreading. In this report, we demonstrate that VASP is a target for cGK regulation of neutrophil spreading. We showed that VASP was in its dephosphorylated form in retracted round neutrophils and was rapidly phosphorylated by cGK at the onset of cell spreading. Both adherence and the onset of cell spreading induced significant elevations of cGMP in neutrophils. When neutrophils were incubated with 8-Br-cGMP, a direct activator of cGK, cells became more polarized in suspension, and spread more rapidly during adhesion. Our observations that ...
cGMP-dependent protein kinases (PKG) exhibit diverse physiological functions in the mammalian system e.g., in vascular and gastrointestinal smooth muscles, in platelets, in kidney, in bone growth, nociception and in the central nervous system. Furthermore, PKG were found in insects and in the malaria parasite Plasmodium falciparum. Two different genes of PKG exist: a) the PKG-I gene that is expressed as cytosolic PKG-Iα or PKG-Iβ isoform, and b) the PKG-II gene, which expresses the membrane associated PKG-II protein. The enzyme kinetics, the localization and the substrates of these PKG enzymes differ utilizing different physiological functions. Various inhibitors of PKG were developed directed against diverse functional regions of the kinase. These inhibitors of PKG have been used to analyse the specific functions of these enzymes. The review article will summarize these different inhibitors regarding their specificity and their present applications in vitro and in vivo. Furthermore, it will be

The Association Study of PRKG1 Gene Polymorphism and Salt-Sensitive Hypertension among the Essential Hypertension in Beijing Abstract.
The report by Castro et al demonstrates that PKG activation in response to ANP activation of pGC elicits a strong feed-forward mechanism that further enhances cGMP production in the subsarcolemmal pool (Figure). The protein target of PKG that elicits this effect is unknown. Notably, this is the first feed-forward effect to be defined for cGMP signaling in any tissue. Surprisingly, it appears that there is little activation of PDE2 activity through cGMP binding to its allosteric sites, which should counter the effect, and the mechanism for terminating the feed-forward signal is not determined. Moreover, the mechanism whereby PDE2 is selectively localized to this cGMP pool is unknown.. In contrast, increased cGMP production by NO-GC elicits the opposite effect on cGMP levels by activating a negative-feedback regulation of cytosolic cGMP; this is mediated by activation of PKG, which phosphorylates and activates PDE5. The resulting increased cGMP breakdown blunts further elevation of cGMP and lowers ...
Families will be able to identify relatives with mutation, take steps to monitor and treat. A multi-institutional team led by Dianna Milewicz, M.D., Ph.D., of The University of Texas Health Science Center at Houston (UTHealth) has found a recurrent genetic mutation that has been linked to deadly thoracic aortic dissections in family members as young as 17 years of age.. The gene known as PRKG1 makes a protein called cGMP-dependent kinase, type I. The PRKG1 mutation alters the function of the protein and causes the muscle cells in the wall of the aorta to respond incorrectly to pulsatile blood flow from the heart, and the change in this one protein ultimately causes thoracic aortic aneurysm and acute aortic dissection. The mutation was identified in four families, including three in the United States. The majority of the affected family members suffered acute aortic dissections at young ages (17 to 51 years).. What is unique about this finding is that we identified four unrelated families from ...
The protein encoded by this gene is a regulatory subunit of cyclic AMP-dependent protein kinase A (PKA), which is involved in the signaling pathway of the second messenger cAMP. Two regulatory and two catalytic subunits form the PKA holoenzyme, disbands after cAMP binding. The holoenzyme is involved in many cellular events, including ion transport, metabolism, and transcription. Several transcript variants encoding the same protein have been found for this gene.

TY - JOUR. T1 - Phosphorylation of tyrosine hydroxylase by cyclic GMP - Dependent protein kinase. AU - Roskoski, R.. AU - Vulliet, Philip R. AU - Glass, D. B.. PY - 1987. Y1 - 1987. N2 - Tyrosine hydroxylase purified from rat pheochromycytoma was phosphorylated and activated by purified cyclic GMP-dependent protein kinase as well as by cyclic AMP-dependent protein kinase catalytic subunit. The extent of activation was correlated with the degree of phosphate incorporated into the enzyme. Comparable stoichiometric ratios (0.6 mol phosphate/mol tyrosine hydroxylase subunit) were obtained at maximal concentrations of either cyclic AMP-dependent or cyclic GMP-dependent protein kinases. The enzymes appeared to mediate the phosphorylation of the same residue based on the observation that incorporation was not increased when both enzymes were present. The major tryptic phosphopeptide obtained from tyrosine hydroxylase phosphorylated by each protein kinase exhibited an identical retention time following ...
