A class of cellular receptors that have an intrinsic PROTEIN-TYROSINE KINASE activity.
Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.
Highly conserved protein-serine threonine kinases that phosphorylate and activate a group of AGC protein kinases, especially in response to the production of the SECOND MESSENGERS, phosphatidylinositol 3,4,-biphosphate (PtdIns(3,4)P2) and phosphatidylinositol 3,4,5-triphosphate (PtdIns(3,4,5)P3).

Inhibition of T cell activation by cyclic adenosine 5'-monophosphate requires lipid raft targeting of protein kinase A type I by the A-kinase anchoring protein ezrin. (1/23)

cAMP negatively regulates T cell immune responses by activation of type I protein kinase A (PKA), which in turn phosphorylates and activates C-terminal Src kinase (Csk) in T cell lipid rafts. Using yeast two-hybrid screening, far-Western blot, immunoprecipitation and immunofluorescense analyses, and small interfering RNA-mediated knockdown, we identified Ezrin as the A-kinase anchoring protein that targets PKA type I to lipid rafts. Furthermore, Ezrin brings PKA in proximity to its downstream substrate Csk in lipid rafts by forming a multiprotein complex consisting of PKA/Ezrin/Ezrin-binding protein 50, Csk, and Csk-binding protein/phosphoprotein associated with glycosphingolipid-enriched microdomains. The complex is initially present in immunological synapses when T cells contact APCs and subsequently exits to the distal pole. Introduction of an anchoring disruptor peptide (Ht31) into T cells competes with Ezrin binding to PKA and thereby releases the cAMP/PKA type I-mediated inhibition of T cell proliferation. Finally, small interfering RNA-mediated knockdown of Ezrin abrogates cAMP regulation of IL-2. We propose that Ezrin is essential in the assembly of the cAMP-mediated regulatory pathway that modulates T cell immune responses.  (+info)

Prostaglandin E2 inhibits tumor necrosis factor-alpha RNA through PKA type I. (2/23)

Tumor necrosis factor-alpha (TNF-alpha) is a cytokine that may contribute to the pathogenesis of septic shock, rheumatoid arthritis, cancer, and diabetes. Prostaglandins endogenously produced by macrophages act in an autocrine fashion to limit TNF-alpha production. We investigated the timing and signaling pathway of prostaglandin-mediated inhibition of TNF-alpha production in Raw 264.7 and J774 macrophages. TNF-alpha mRNA levels were rapidly modulated by PGE(2) or carbaprostacylin. PGE(2) or carbaprostacyclin prevented and rapidly terminated on-going TNF-alpha gene transcription within 15 min of prostaglandin treatment. Selective activation of PKA type I, but not PKA type II or Epac, with chemical analogs of cAMP was sufficient to inhibit LPS-induced TNF-alpha mRNA levels. The mechanisms by which prostaglandins limit TNF-alpha mRNA levels may underlie endogenous regulatory mechanisms that limit inflammation, and may have important implications for understanding chronic inflammatory disease pathogenesis.  (+info)

The stabilisation of acetylcholine receptors (AChRs) at the neuromuscular junction depends on muscle activity and the cooperative action of myosin Va and protein kinase A (PKA) type I. To execute its function, PKA has to be present in a subsynaptic microdomain where it is enriched by anchoring proteins. Here, we show that the AChR-associated protein, rapsyn, interacts with PKA type I in C2C12 and T-REx293 cells as well as in live mouse muscle beneath the neuromuscular junction. Molecular modelling, immunoprecipitation and bimolecular fluorescence complementation approaches identify an α-helical stretch of rapsyn to be crucial for binding to the dimerisation and docking domain of PKA type I. When expressed in live mouse muscle, a peptide encompassing the rapsyn α-helical sequence efficiently delocalises PKA type I from the neuromuscular junction. The same peptide, as well as a rapsyn construct lacking the α-helical domain, induces severe alteration of acetylcholine receptor turnover as well as
en] Murine AIDS (MAIDS) is caused by infection with the murine leukemia retrovirus RadLV-Rs and is characterized by T-cell anergy and severe immunodeficiency with increased susceptibilty to several experimental opportunistic infections as observed in HIV infection. T cell anergy is associated with an increase of intracellular cAMP level, triggering a multistep pathway involving activation of PKA type I and resulting in inhibition of proximal TCR signaling. We have reviously demonstrated that blocking PKA type I using the selective inhibitor Rp-8-Br-cAMPS, restores T-cell function in vitro in MAIDS as well as in HIV infection. In the present report, we investigated the effect of parenteral administration of Rp-8-Br-cAMPS in mice with MAIDS. We show that the compound is not toxic and partially restores the ex vivo proliferative responses to anti-CD3 mAb, but that it has no effect on the lymphadenopathy and splenomegaly characterizing ...

Combinatorial assembly of catalytic and regulatory subunits results in diverse isoforms of the PKA family. Their quaternary structures differ substantially (Taylor et al., 2012). A detailed analysis of isoform-specific cellular functions, however, remains challenging. Approaches to directly detect the activation of endogenous isoforms in primary cells models are largely missing. It was unclear whether changes in RII phosphorylation reflect the process of PKA-II activation. Early biochemical studies on PKA-II purified from bovine cardiac muscle showed that a large proportion of PKA-II is phosphorylated in vivo (Rangel-Aldao et al., 1979). Another report suggests that RII subunits are fully phosphorylated in non-stimulated cardiomyocytes (Manni et al., 2008). Accordingly, these researchers found that activation of PKA resulted in a phosphatase-dependent loss of basal RII phosphorylation detected in cell lysates (Manni et al., 2008). The assumption that RII subunits are fully phosphorylated in the ...

RATIONALE: cAMP and cGMP are intracellular second messengers involved in heart pathophysiology. cGMP can potentially affect cAMP signals via cGMP-regulated phosphodiesterases (PDEs). OBJECTIVE: To study the effect of cGMP signals on the local cAMP response to catecholamines in specific subcellular compartments. METHODS AND RESULTS: We used real-time FRET imaging of living rat ventriculocytes expressing targeted cAMP and cGMP biosensors to detect cyclic nucleotides levels in specific locales. We found that the compartmentalized, but not the global, cAMP response to isoproterenol is profoundly affected by cGMP signals. The effect of cGMP is to increase cAMP levels in the compartment where the protein kinase (PK)A-RI isoforms reside but to decrease cAMP in the compartment where the PKA-RII isoforms reside. These opposing effects are determined by the cGMP-regulated PDEs, namely PDE2 and PDE3, with the local activity of these PDEs being critically important. The cGMP-mediated modulation of cAMP also affects
