Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Specialized junctions at which a neuron communicates with a target cell. At classical synapses, a neuron's presynaptic terminal releases a chemical transmitter stored in synaptic vesicles which diffuses across a narrow synaptic cleft and activates receptors on the postsynaptic membrane of the target cell. The target may be a dendrite, cell body, or axon of another neuron, or a specialized region of a muscle or secretory cell. Neurons may also communicate via direct electrical coupling with ELECTRICAL SYNAPSES. Several other non-synaptic chemical or electric signal transmitting processes occur via extracellular mediated interactions.

Diminished levels of protein kinase A RI alpha and RI beta transcripts and proteins in systemic lupus erythematosus T lymphocytes. (1/17)

Deficient type I protein kinase A phosphotransferase activity occurs in the T cells of 80% of subjects with systemic lupus erythematosus (SLE). To investigate the mechanism of this deficient isozyme activity, we hypothesized that reduced amounts of type I regulatory (RI) isoform transcripts, RIalpha and RIbeta, may be associated with a diminution of RIalpha and/or RIbeta protein. Sixteen SLE subjects with a mean (+/-1 SD) SLE disease activity index of 12.4 +/- 7.2 were studied. Controls included 16 normal subjects, six subjects with primary Sjogren's syndrome (SS), and three subjects with SS/SLE overlap. RT-PCR revealed that normal, SS, SS/SLE, and SLE T cells expressed mRNAs for all seven R and catalytic (C) subunit isoforms. Quantification of mRNAs by competitive PCR revealed that the ratio of RIalpha mRNA to RIbeta mRNA in normal T cells was 3.4:1. In SLE T cells there were 20 and 49% decreases in RIalpha and RIbeta mRNAs (RIbeta; p = 0.008), respectively, resulting in an RIalpha:RIbeta mRNA of 5.3:1. SS/SLE T cells showed a 72.5% decrease in RIbeta mRNA compared with normal controls (p = 0.01). Immunoblotting of normal T cell RIalpha and RIbeta proteins revealed a ratio of RIalpha:RIbeta of 3.2:1. In SLE T cells, there was a 30% decrease in RIalpha protein (p = 0.002) and a 65% decrease in RIbeta protein (p < 0.001), shifting the ratio of RIalpha:RIbeta protein to 6.5:1. T cells from 25% of SLE subjects lacked any detectable RIbeta protein. Analysis of several lupus T cell lines demonstrated a persistent deficiency of both proteins, excluding a potential effect of disease activity. In conclusion, reduced expression of RIalpha and RIbeta transcripts is associated with a decrement in RIalpha and RIbeta proteins and may contribute to deficient type I protein kinase A isozyme activity in SLE T cells.  (+info)

Protein kinase A RI beta subunit deficiency in lupus T lymphocytes: bypassing a block in RI beta translation reconstitutes protein kinase A activity and augments IL-2 production. (2/17)

A profound deficiency of type I protein kinase A (PKA-I or RIalpha/beta2C2) phosphotransferase activity occurs in the T lymphocytes of 80% of subjects with systemic lupus erythematosus (SLE), an autoimmune disorder of unknown etiology. This isozyme deficiency is predominantly the product of reduced or absent beta isoform of the type I regulatory subunit (RIbeta). Transient transfection of RIbeta cDNAs from SLE subjects into autologous T cells that do not synthesize the RIbeta subunit bypassed the block, resulting in RIbeta subunit synthesis and restoration of the PKA-Ibeta (RIbeta2C2) holoenzyme. Transfected T cells activated via the T cell surface receptor complex revealed a significant increase of cAMP-activatable PKA activity that was associated with a significant increase in IL-2 production. These data demonstrate that a disorder of RIbeta translation exists, and that correction of the PKA-I deficiency may enhance T lymphocyte effector functions in SLE.  (+info)

Dibutyryl cAMP treatment of neuroblastoma-glioma hybrid cells results in selective increase in cAMP-receptor protein (R-I) as measured by monospecific antibodies. (3/17)

The absolute levels of cAMP-dependent protein kinase (cAMP-dPK) subunits (R-I, R-II and C) and cGMP-dependent protein kinase (cGMP-dPK) holoenzyme were studied in neuroblastoma-glioma hybrid cells before and after dibutyryl-cAMP (Bt2cAMP) treatment which results in differentiation of these cells. The levels were determined by two different techniques utilizing antibodies which had been raised against each individual purified protein kinase subunit (or the holoenzyme in the case of the cGMP-dPK). Electrophoretic transfer of samples from SDS-polyacrylamide gels to nitrocellulose paper, followed by immunolabeling of protein kinase subunits with their respective antibodies and [125I]Protein A, demonstrated the monospecific nature of the antibodies, and a selective, several-fold increase in the R-I subunit in Bt2cAMP-treated cells, with no change in the level of R-II or C subunits. A simple enzyme-linked immunosorbent assay (ELISA) capable of measuring nanogram amounts of the various subunits confirmed the selective increase in the R-I subunit. ELISA assay results also indicated that the R-I subunits present before and after Bt2cAMP treatment are antigenically homologous. In conclusion, the specific, sensitive immunological methods described here demonstrate the capacity of neuroblastoma-glioma hybrid cells to regulate separately the levels of the two distinct subunits (R-I and C) of the Type I cAMP-dPK.  (+info)

Rab32 is an A-kinase anchoring protein and participates in mitochondrial dynamics. (4/17)

A-kinase anchoring proteins (AKAPs) tether the cAMP-dependent protein kinase (PKA) and other signaling enzymes to distinct subcellular organelles. Using the yeast two-hybrid approach, we demonstrate that Rab32, a member of the Ras superfamily of small molecular weight G-proteins, interacts directly with the type II regulatory subunit of PKA. Cellular and biochemical studies confirm that Rab32 functions as an AKAP inside cells. Anchoring determinants for PKA have been mapped to sites within the conserved alpha5 helix that is common to all Rab family members. Subcellular fractionation and immunofluorescent approaches indicate that Rab32 and a proportion of the cellular PKA pool are associated with mitochondria. Transient transfection of a GTP binding-deficient mutant of Rab32 promotes aberrant accumulation of mitochondria at the microtubule organizing center. Further analysis of this mutant indicates that disruption of the microtubule cytoskeleton results in aberrantly elongated mitochondria. This implicates Rab32 as a participant in synchronization of mitochondrial fission. Thus, Rab32 is a dual function protein that participates in both mitochondrial anchoring of PKA and mitochondrial dynamics.  (+info)

Hippocampal long-term depression and depotentiation are defective in mice carrying a targeted disruption of the gene encoding the RI beta subunit of cAMP-dependent protein kinase. (7/17)

The cAMP-dependent protein kinase (PKA) has been shown to play an important role in long-term potentiation (LTP) in the hippocampus, but little is known about the function of PKA in long-term depression (LTD). We have combined pharmacologic and genetic approaches to demonstrate that PKA activity is required for both homosynaptic LTD and depotentiation and that a specific neuronal isoform of type I regulatory subunit (RI beta) is essential. Mice carrying a null mutation in the gene encoding RI beta were established by use of gene targeting in embryonic stem cells. Hippocampal slices from mutant mice show a severe deficit in LTD and depotentiation at the Schaffer collateral-CA1 synapse. This defect is also evident at the lateral perforant path-dentate granule cell synapse in RI beta mutant mice. Despite a compensatory increase in the related RI alpha protein and a lack of detectable changes in total PKA activity, the hippocampal function in these mice is not rescued, suggesting a unique role for RI beta. Since the late phase of CA1 LTP also requires PKA but is normal in RI beta mutant mice, our data further suggest that different forms of synaptic plasticity are likely to employ different combinations of regulatory and catalytic subunits.  (+info)

Mutagenesis of the regulatory subunit (RII beta) of cAMP-dependent protein kinase II beta reveals hydrophobic amino acids that are essential for RII beta dimerization and/or anchoring RII beta to the cytoskeleton. (8/17)

In neurons cAMP-dependent protein kinase II beta (PKAII beta) is sequestered in the dendritic cytoskeleton because the regulatory subunit (RII beta) of the enzyme is tightly bound by A Kinase Anchor Proteins (AKAPs). The prototypic neuronal anchor protein AKAP75 has a COOH-terminal 22-residue RII beta binding (tethering) site. A key feature of the tethering site is that several amino acids with large aliphatic side chains mediate the high-affinity binding of RII beta. Mutagenesis, recombinant protein expression, and physicochemical characterization were used to investigate the structural basis for the homodimerization and AKAP75 binding activities of RII beta. Several crucial residues are located in an NH2-terminal region that encompasses amino acids 13-36. Substitution of Ala for Leu13 or Phe36 generates monomeric RII beta subunits that cannot bind AKAP75. The results are not due to general misfolding since mutant RII beta monomers bind cAMP and inhibit the catalytic subunit of PKAII beta with the same affinity and efficacy as wild-type RII beta dimers. Moreover, substitution of Ala for Leu12, Val20, Leu21, Phe31, Leu33, or Leu39 and replacement of Leu13 with Ile or Val did not impair the dimerization reaction. Evidently, large hydrophobic side chains of Leu13 and Phe36 play pivotal roles in stabilizing RII beta-RII beta interactions. A secondary consequence of destabilizing RII beta dimers is the loss of intracellular targeting/anchoring capacity because monomers fail to bind AKAP75. Other NH2-terminal residues directly modulate the affinity of RII beta dimers for the AKAP75 tethering site. Replacement of Val20-Leu21 with Ala-Ala produced a dimeric RII beta protein that binds AKAP75 approximately 4% as avidly as wild-type RII beta. It is possible that the aliphatic side chains of Val20 and Leu21 interact with the essential Leu and Ile residues in the AKAP75 tethering region.  (+info)

The neurofibromatosis 2 (NF2) tumor suppressor protein merlin is commonly mutated in human benign brain tumors. The gene altered in NF2 was located on human chromosome 22q12 in 1993 and the encoded protein named merlin and schwannomin. Merlin has homology to ERM family proteins, ezrin, radixin, and moesin, within the protein 4.1 superfamily.
