Human Polyclonal PRKACA Primary Antibody for ELISA, WB - ABIN562366 : Adachi, Kano, Saido, Murata: Visual screening and analysis for kinase-regulated membrane trafficking pathways that are involved in extensive beta-amyloid secretion. in Genes to cells : devoted to molecular & cellular mechanisms 2009 (PubMed)
Ezrin (show EZR Antibodies)-anchored PKA phosphorylates serine 369 and 373 on connexin 43 (show GJA1 Antibodies) to enhance gap junction assembly, communication, and cell fusion.
CaV1.4 (show CACNA1F Antibodies) channels are indeed modulated by PKA phosphorylation within the inhibitor of Ca(2 (show CA2 Antibodies)+)-dependent inactivation (ICDI) motif.
In this study, the authors linked for the first time the loss of RIIbeta (show PRKAR2B Antibodies) protein levels to the PRKACA mutation status and found the down-regulation of RIIbeta (show PRKAR2B Antibodies) to arise post-transcriptionally.
the presence of lipofuscin in cortisol-producing adenomas (CPAs) responsible for Cushing syndrome with and without the PRKACA (pLeu206Arg) somatic mutation, was investigated.
Mechanistically, Sirt1 (show SIRT1 Antibodies) expression elevates phosphorylation of the alpha subunit (show POLG Antibodies) of protein kinase A (PKA alpha), and this event is essential for Sirt1 (show SIRT1 Antibodies)-induced phosphorylation of beta Catenin (show CTNNB1 Antibodies).
Together, the results suggest a complex antagonistic interplay between the control of ARPP-16 (show ARPP19 Antibodies) by MAST3 and PKA that creates a mechanism whereby cAMP mediates PP2A (show PPP2R4 Antibodies) disinhibition.
CTR (show CALCR Antibodies) activates AKAP2 (show AKAP2 Antibodies)-anchored cAMP-dependent protein kinase A, which then phosphorylates tight junction proteins ZO-1 (show TJP1 Antibodies) and claudin 3 (show CLDN3 Antibodies).
These results indicate that Mixed fibrolamellar hepatocellular carcinoma (mFL-HCC (show FAM126A Antibodies)) is similar to pure FL-HCC (show FAM126A Antibodies) at the genomic level and the DNAJB1 (show DNAJB1 Antibodies):PRKACA fusion can be used as a diagnostic tool for both pure and mFL-HCC (show FAM126A Antibodies)
PRKACA mutations are highly specific for cortisol over-secretion, while they are absent or very rare in the context of other adrenal diseases. Patients carrying these somatic mutations are affected by a more severe phenotype and are identified at a younger age.
Somatic mutations in PRKACA, coding for the catalytic alpha subunit (show POLG Antibodies) of protein kinase A (PKA), have been recently identified as the most frequent genetic alteration in cortisol-secreting adrenocortical adenomas, which are responsible for adrenal Cushing's syndrome.
PKA and MEK (thus, also pERK) are the intracellular mediators downstream of GPR30 that induce the non-genomic suppression of GnRH-induced LH secretion from bovine AP cells by estradiol or G1
Data indicate that mitochondrial cAMP-dependent protein kinase (PKA) activity is regulated by the protease calpain.
structural basis of selectivity for protein kinase A in complex with Rho-kinase (show ROCK1 Antibodies) inhibitors by x-ray crystallography
Purification and characterisation of protein kinase catalytic subunit (PKAcat) from bovine lens.
ceramide as a potent physiological modulator of the Na(+)-ATPase (show DNAH8 Antibodies), participating in a regulatory network in kidney cells and counteracting the stimulatory effect of PKA via PKCzeta (show PRKCZ Antibodies)
we demonstrate that PKA, PKC (show FYN Antibodies) and PI3K pathways crosstalk in porcine male germ cells to crucially regulate GSK3A (show GSK3a Antibodies) phosphorylation which subsequently controls cell motility.
Study validates the DNAJB1 (show DNAJB1 Antibodies)-PRKACA fusion kinase as an oncogenic driver and candidate drug target for fibrolamellar hepatocellular carcinoma in mouse model in which tumorigenesis was significantly enhanced by genetic activation of beta-catenin (show CTNNB1 Antibodies).
Protein kinase A signaling explains vasopressin (show AVP Antibodies)-mediated regulation of membrane trafficking and gene transcription.
Data suggest that the upregulation of mitochondrial respiratory chain proteins played a partial role in the protection of PKA/CREB (show CREB1 Antibodies) signaling.
HIF1a (show HIF1A Antibodies) transcriptional activity is stimulated by Protein kinase A-dependent phosphorylation
Generation of the Dnajb1 (show DNAJB1 Antibodies)-Prkaca fusion gene in wild-type mice to be sufficient to initiate formation of tumors that have many features of human fibrolamellar hepatocellular carcinonma.
Data indicate a subpopulation of the CaV1.2 (show CACNA1C Antibodies) channel pore-forming subunit (alpha1C) within nanometer proximity of protein kinase A (PKA) at the sarcolemma of murine and human arterial myocytes.
S1928A KI mice failed to induce long-term potentiation in response to prolonged theta-tetanus (PTT-LTP (show SCP2 Antibodies)), a form of synaptic plasticity that requires Cav1.2 (show CACNA1C Antibodies) and enhancement of its activity by the beta2-adrenergic receptor (show ADRB2 Antibodies) (beta2AR (show ADRB2 Antibodies))-cAMP-PKA cascade.
Data show that laminin alpha2beta1gamma1 (Lm211) can inhibit neuregulin 1 (show NRG1 Antibodies) type III (Nrg1III) by limiting protein kinase A (PKA) activation, which is required to initiate myelination.
study identifies a new role of Dual-AKAP1 (show AKAP1 Antibodies) in regulating mitochondrial trafficking through Miro-2 (show RHOT2 Antibodies), and supports a model in which PINK1 (show PINK1 Antibodies) and mitochondrial PKA participate in a similar neuroprotective signaling pathway to maintain dendrite connectivity
Data suggest that enzyme activation by cAMP involves highly stable conformation of Prkar1a as it binds to Prkaca; glycine residue, G235, appears to function as hinge in B/C helix conserved in Prkar1a; this "Flipback" conformation plays role in cAMP association to A domain of Prkar1a. (Prkar1a = cyclic AMP-dependent protein kinase RIalpha subunit; Prkaca = cyclic AMP-dependent protein kinase catalytic subunit)
support hypothesis that PRKACA activation is responsible for downstream protein tyrosine phosphorylation events in stallion sperm
Thus Ca(2 (show CA2 Antibodies)+)-cAMP/PKA-dependent phosphorylation limits the rate and magnitude of increase in spontaneous action potential firing rate.
cAMP is a signaling molecule important for a variety of cellular functions. cAMP exerts its effects by activating the cAMP-dependent protein kinase, which transduces the signal through phosphorylation of different target proteins. The inactive kinase holoenzyme is a tetramer composed of two regulatory and two catalytic subunits. cAMP causes the dissociation of the inactive holoenzyme into a dimer of regulatory subunits bound to four cAMP and two free monomeric catalytic subunits. Four different regulatory subunits and three catalytic subunits have been identified in humans. The protein encoded by this gene is a member of the Ser/Thr protein kinase family and is a catalytic subunit of cAMP-dependent protein kinase. Alternatively spliced transcript variants encoding distinct isoforms have been observed.
