Association of cyclic-AMP-dependent protein kinase with neurofilaments [PDF]
Neurofilament preparations isolated from bovine spinal cord contain cyclic-AMP-dependent protein kinase (PKA) activity. Treatment of this preparation with cyclic AMP, to dissociate the regulatory subunit of the kinase from the catalytic subunit, resulted in retention of the kinase activity but loss of cyclic AMP regulation.

Kv4.2 Phosphorylation by Cyclic AMP-dependent Protein Kinase [PDF]
Recent evidence suggests that K(+) channels composed of Kv4.2 alpha-subunits underlie a transient current in hippocampal CA1 neurons and ventricular myocytes, and activation of the cAMP second messenger cascade has been shown to modulate this transient current. We determined if Kv4.2 alpha-subunits were directly phosphorylated by cAMP-dependent protein

Regulation of transcription by cyclic AMP-dependent protein kinase. [PDF]
cAMP-dependent protein kinase (PKA; ATP: protein phosphotransferase; EC 2.7.1.37) appears to be the major mediator of cAMP responses in mammalian cells. We have investigated the role of PKA subunits in the regulation of specific genes in response to cAMP by cotransfection of wild-type or mutant subunits of PKA together with cAMP-inducible reporter ...

Substrate specificity of the cyclic AMP-dependent protein kinase. [PDF]
The protein substrate specificity of the catalytic subunit of rabbit skeletal muscle cyclic AMP-dependent protein kinase (EC 2.7.1.37; ATP:protein phosphotransferase) has been studied using genetic variants of beta casein. It was found that beta casein-B was phosphorylated at a much greater rate than beta caseins A1, A2, A3, or C.

Yeast cyclic AMP‐dependent protein kinase [PDF]
We have purified cyclic AMP‐dependent protein kinase from the yeast Saccharomyces cerevisiae. The purified enzyme was inactive in the absence of cyclic AMP and displayed two protein bands on SDS gel electrophoresis. One was identified as the cAMP‐binding protein by chromatography on cAMP‐agarose. M r of the latter was 50 000 while the catalytic subunit

Ezrin is a cyclic AMP-dependent protein kinase anchoring protein [PDF]
cAMP-dependent protein kinase (A-kinase) anchoring proteins (AKAPs) are responsible for the subcellular sequestration of the type II A-kinase. Previously, we identified a 78 kDa AKAP which was enriched in gastric parietal cells. We have now purified the 78 kDa AKAP to homogeneity from gastric fundic mucosal supernates using type II A-kinase regulatory ...

Cyclic AMP‐dependent protein kinase does not phosphorylate cyclic GMP‐dependent protein kinase in vitro [PDF]
The autophosphorylation reaction of purified cGMP‐dependent protein kinase has been studied. Apparent initial rates of autophosphorylation in the absence of cyclic nucleotides and in the presence of cGMP and cAMP are 0.006, 0.04, 0.4 mol. Pi incorp./min−1.mol cGMP‐kinase subunit−1.

Protein phosphorylation in yeast mitochondria [PDF]
We describe the identification and submitochondrial localization of four protein kinases and of their target proteins in derepressed yeast mitochondria. The activity of one of the kinases depends on the presence of cyclic AMP (cAMP).

Resveratrol inhibits inflammatory responses via the mammalian target of rapamycin signaling pathway in cultured LPS-stimulated microglial cells. [PDF]
Resveratrol have been known to possess many pharmacological properties including antioxidant, cardioprotective and anticancer effects. Although current studies indicate that resveratrol produces neuroprotection against neurological disorders, the precise

Role of cyclic AMP in the control of cell-specific gene expression [PDF]
Genes have to be expressed in specific cell types at appropriate times of development dependent on external signals. cAMP signaling occurs in all cells, thus raising the question of how this signal transduction pattern is integrated into mechanisms ...
