RAS and beyond: the many faces of the neurofibromatosis type 1 protein
Neurofibromatosis type 1 is a rare neurogenetic syndrome, characterized by pigmentary abnormalities, learning and social deficits, and a predisposition for benign and malignant tumor formation caused by germline mutations in the NF1 gene.

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).

Objective: Upon activation, G protein coupled receptors (GPCRs) associate with heterotrimeric G proteins at the plasma membrane to initiate second messenger signaling. Subsequently, the activated receptor experiences desensitization, internalization, and

3',5'-Cyclic Adenosine Monophosphate- and Ca2+-Calmodulin-Dependent Endogenous Protein Phosphorylation Activity in Membranes of the Bovine Chromaffin Secretory Vesicles: Identification of Two Phosphorylated Components as Tyrosine Hydroxylase and Protein Kinase Regulatory Subunit Type II [PDF]
: Membranes of the secretory vesicles from bovine adrenal medulla were investigated for the presence of the endogenous protein phosphorylation activity. Seven phosphoprotein bands in the molecular weight range of 250,000 to 30,000 were observed by means ...

The cell cycle is controlled by microtubule-associated serine/threonine kinase-like (MASTL), which phosphorylates the cAMP-regulated phosphoproteins 19 (ARPP19) at S62 and 19e/α-endosulfine (ENSA) at S67and converts them into protein phosphatase 2A (

Fate and regulation of anterior-like cells in Dictyostelium slugs [PDF]
A pattern of two tissue types exists in the Dictyostelium slug. Contained within the posterior tissue are anterior-like cells which comprise about 10% of the developing cell mass.

Cyclic AMP metabolism in adipose tissue of exercise-trained rats.
Cyclic AMP metabolism in epididymal adipose tissue of exercise-trained rats was examined to determine if training induced changes in cyclic AMP production or inactivation.

The role of type 4 phosphodiesterases in generating microdomains of cAMP: Large scale stochastic simulations [PDF]
Cyclic AMP (cAMP) and its main effector Protein Kinase A (PKA) are critical for several aspects of neuronal function including synaptic plasticity. Specificity of synaptic plasticity requires that cAMP activates PKA in a highly localized manner despite ...

Short PDE4 Isoforms as Drug Targets in Disease
The second messenger, cyclic adenosine monophosphate (cAMP), is a master regulator of signal transduction that maintains cell homeostasis. A fine balance between cAMP synthesis by adenylyl cyclase and degradation by phosphodiesterases (PDEs) underpins ...
