Differential effects of a calcineurin inhibitor on glutamate-induced phosphorylation of Ca2+/calmodulin-dependent protein kinases in cultured rat hippocampal neurons. (1/181)
Calcium/calmodulin-dependent protein kinases (CaM kinases) are major multifunctional enzymes that play important roles in calcium-mediated signal transduction. To characterize their regulatory mechanisms in neurons, we compared glutamate-induced phosphorylation of CaM kinase IV and CaM kinase II in cultured rat hippocampal neurons. We observed that dephosphorylation of these kinases followed different time courses, suggesting different regulatory mechanisms for each kinase. Okadaic acid, an inhibitor of protein phosphatase (PP) 1 and PP2A, increased the phosphorylation of both kinases. In contrast, cyclosporin A, an inhibitor of calcineurin, showed different effects: the phosphorylation and activity of CaM kinase IV were significantly increased with this inhibitor, but those of CaM kinase II were not significantly increased. Cyclosporin A treatment of neurons increased phosphorylation of Thr196 of CaM kinase IV, the activated form with CaM kinase kinase, which was recognized with an anti-phospho-Thr196 antibody. Moreover, recombinant CaM kinase IV was dephosphorylated and inactivated with calcineurin as well as with PP1, PP2A, and PP2C in vitro. These results suggest that CaM kinase IV, but not CaM kinase II, is directly regulated with calcineurin. (+info)Inhibition of the Ca2+/calmodulin-dependent protein kinase I cascade by cAMP-dependent protein kinase. (2/181)
Several recent studies have shown that Ca2+/calmodulin-dependent protein kinase I (CaMKI) is phosphorylated and activated by a protein kinase (CaMKK) that is itself subject to regulation by Ca2+/calmodulin. In the present study, we demonstrate that this enzyme cascade is regulated by cAMP-mediated activation of cAMP-dependent protein kinase (PKA). In vitro, CaMKK is phosphorylated by PKA and this is associated with inhibition of enzyme activity. The major site of phosphorylation is threonine 108, although additional sites are phosphorylated with lower efficiency. In vitro, CaMKK is also phosphorylated by CaMKI at the same sites as PKA, suggesting that this regulatory phosphorylation might play a role as a negative-feedback mechanism. In intact PC12 cells, activation of PKA with forskolin resulted in a rapid inhibition of both CaMKK and CaMKI activity. In hippocampal slices CaMKK was phosphorylated under basal conditions, and activation of PKA led to an increase in phosphorylation. Two-dimensional phosphopeptide mapping indicated that activation of PKA led to increased phosphorylation of multiple sites including threonine 108. These results indicate that in vitro and in intact cells the CaMKK/CaMKI cascade is subject to inhibition by PKA-mediated phosphorylation of CaMKK. The phosphorylation and inhibition of CaMKK by PKA is likely to be involved in modulating the balance between cAMP- and Ca2+-dependent signal transduction pathways. (+info)Substrate recognition by Ca2+/Calmodulin-dependent protein kinase kinase. Role of the arg-pro-rich insert domain. (3/181)
Mammalian Ca2+/CaM-dependent protein kinase kinase (CaM-KK) has been identified and cloned as an activator for two kinases, CaM kinase I (CaM-KI) and CaM kinase IV (CaM-KIV), and a recent report (Yano, S., Tokumitsu, H., and Soderling, T. R. (1998) Nature 396, 584-587) demonstrates that CaM-KK can also activate and phosphorylate protein kinase B (PKB). In this study, we identify a CaM-KK from Caenorhabditis elegans, and comparison of its sequence with the mammalian CaM-KK alpha and beta shows a unique Arg-Pro (RP)-rich insert in their catalytic domains relative to other protein kinases. Deletion of the RP-domain resulted in complete loss of CaM-KIV activation activity and physical interaction of CaM-KK with glutathione S-transferase-CaM-KIV (T196A). However, CaM-KK autophosphorylation and phosphorylation of a synthetic peptide substrate were normal in the RP-domain mutant. Site-directed mutagenesis of three conserved Arg in the RP- domain of CaM-KK confirmed that these positive charges are important for CaM-KIV activation. The RP- domain deletion mutant also failed to fully activate and phosphorylate CaM-KI, but this mutant was indistinguishable from wild-type CaM-KK for the phosphorylation and activation of PKB. These results indicate that the RP-domain in CaM-KK is critical for recognition of downstream CaM-kinases but not for its catalytic activity (i.e. autophosphorylation) and PKB activation. (+info)The retinoblastoma susceptibility gene product/Sp1 signalling pathway is modulated by Ca2+/calmodulin kinases II and IV activity. (4/181)
To investigate the possible link between Ca2+ signalling and cell cycle control we analysed Ca2+/calmodulin kinases (CamK) interaction with the retinoblastoma susceptibility gene product/SP1 pathway. CamK II and IV activate c-fos transcription through a short promoter region (-99 to -53) containing the retinoblastoma control element (RCE) and a cAMP response element (CRE) related sequences. Deletion analysis revealed that the RCE is a major CamK responsive element and is sufficient to confer CamK and Ca2+ regulation to a minimal promoter. Direct interactions between SP1 and RCE were confirmed by gel shift experiments. Using transient transfection experiments, we show that CamK-dependent transcription is regulated by the retinoblastoma (Rb) susceptibility gene product and the p107 Rb related protein. However, the stimulatory effects of CamKs and Rb on c-fos are blocked by overexpression of both proteins. These effects appear to be directly mediated by SP1 as shown by the use of a Gal4/SP1 fusion proteins. In conclusion, CamK II and IV, two major Ca2+-dependent intracellular effectors, may represent a molecular link between this second messenger transduction pathway and effectors that control cell cycle progression through Rb/SP1 signalling pathway. (+info)A late phase of cerebellar long-term depression requires activation of CaMKIV and CREB. (5/181)
Recently, it has been shown that cerebellar LTD has a late phase that may be blocked by protein synthesis inhibitors. To understand the mechanisms underlying the late phase, we interfered with the activation of transcription factors that might couple synaptic activation to protein synthesis. Particle-mediated transfection of cultured Purkinje neurons with an expression vector encoding a dominant inhibitory form of CREB resulted in a nearly complete blockade of the late phase. Kinases that activate CREB were inhibited, and LTD was assessed. Inhibition of PKA or the MAPK/RSK cascades were without effect on the late phase, while constructs designed to interfere with CaMKIV function attenuated the late phase. These results indicate that the activation of CaMKIV and CREB are necessary to establish a late phase of cerebellar LTD. (+info)Ca(2+)-dependent gene expression mediated by MEF2 transcription factors. (6/181)
Ca(2+) induction of a subset of cellular and viral immediate-early activation genes in lymphocytes has been previously mapped to response elements recognized by the MEF2 family of transcription factors. Here, we demonstrate that Ca(2+) activation of MEF2 response elements in T lymphocytes is mediated in synergy by two Ca(2+)/calmodulin-dependent enzymes, the phosphatase calcineurin, and the kinase type IV/Gr (CaMKIV/Gr), which promote transcription by the MEF2 family members MEF2A and MEF2D. Calcineurin up-regulates the activity of both factors by an NFAT-dependent mechanism, while CaMKIV/Gr selectively and independently activates MEF2D. These results identify MEF2 proteins as effectors of a pathway of gene induction in T lymphocytes which integrates diverse Ca(2+) activation signals and may be broadly operative in several tissues. (+info)Activation of orphan receptor-mediated transcription by Ca(2+)/calmodulin-dependent protein kinase IV. (7/181)
Retinoid-related receptor alpha (RORalpha) is an orphan nuclear receptor that constitutively activates transcription from its cognate response element. We show that RORalpha is Ca(2+ )responsive, and a Ca(2+)/calmodulin-independent form of Ca(2+)/calmodulin-dependent protein kinase IV (CaMKIV) potentiates RORalpha-dependent transcription 20- to 30-fold. Other orphan receptors including RORalpha2, RORgamma and COUP-TFI are also potentiated by CaMKIV. Transcriptional activation by CaMKIV is orphan receptor selective and does not occur with either the thyroid hormone or estrogen receptor. CaMKIV does not phosphorylate RORalpha or its ligand-binding domain (LBD) in vitro, although the LBD is essential for transactivation. Therefore, the RORalpha LBD was used in the mammalian two-hybrid assay to identify a single class of small peptide molecules containing LXXLL motifs that interacted with greater affinity in the presence of CaMKIV. This class of peptides antagonized activation of orphan receptor-mediated transcription by CaMKIV. These studies demonstrate a pivotal role for CaMKIV in the regulation of orphan receptor-mediated transcription. (+info)Ca(2+)/calmodulin-dependent protein kinase IV is expressed in spermatids and targeted to chromatin and the nuclear matrix. (8/181)
Ca(2+)/calmodulin-dependent protein kinase IV and calspermin are two proteins encoded by the Camk4 gene. Both are highly expressed in the testis, where in situ hybridization studies in rat testes have demonstrated that CaMKIV mRNA is localized to pachytene spermatocytes, while calspermin mRNA is restricted to spermatids. We have examined the expression patterns of both CaMKIV and calspermin in mouse testis and unexpectedly find that CaMKIV is expressed in spermatogonia and spermatids but excluded from spermatocytes, while calspermin is found only in spermatids. CaMKIV and calspermin expression in the testis are stage-dependent and appear to be coordinately regulated. In germ cells, we find that CaMKIV is associated with the chromatin. We further demonstrate that a fraction of CaMKIV in spermatids is hyperphosphorylated and specifically localized to the nuclear matrix. These novel findings may implicate CaMKIV in chromatin remodeling during nuclear condensation of spermatids.

Calcium is a chemical element with the symbol Ca and atomic number 20. It is a vital mineral for the human body and is essential for many bodily functions, including bone health, muscle function, nerve transmission, and blood clotting. In the medical field, calcium is often used to diagnose and treat conditions related to calcium deficiency or excess. For example, low levels of calcium in the blood (hypocalcemia) can cause muscle cramps, numbness, and tingling, while high levels (hypercalcemia) can lead to kidney stones, bone loss, and other complications. Calcium supplements are often prescribed to people who are at risk of developing calcium deficiency, such as older adults, vegetarians, and people with certain medical conditions. However, it is important to note that excessive calcium intake can also be harmful, and it is important to follow recommended dosages and consult with a healthcare provider before taking any supplements.
Cyclic AMP-dependent protein kinase type II (PKA II) is a type of protein kinase enzyme that plays a crucial role in regulating various cellular processes in the body. It is activated by the presence of cyclic AMP (cAMP), a second messenger molecule that is produced in response to various stimuli, such as hormones and neurotransmitters.

This phosphorylation can alter the activity, localization, or stability of the target proteins, leading to changes in cellular signaling pathways. PKC enzymes are divided into several subfamilies based on their structure and activation mechanisms. The different subfamilies have distinct roles in cellular signaling and are involved in different diseases. For example, some PKC subfamilies are associated with cancer progression, while others are involved in the regulation of the immune system. Overall, PKC enzymes are an important area of research in the medical field, as they have the potential to be targeted for the development of new therapeutic strategies for various diseases.

For example, the presence of certain isoenzymes in the blood can indicate liver or kidney disease, while changes in the levels of specific isoenzymes in the brain can be indicative of neurological disorders. In addition, isoenzymes can be used as biomarkers for certain diseases or conditions, and can be targeted for therapeutic intervention. For example, drugs that inhibit specific isoenzymes can be used to treat certain types of cancer or heart disease.
Calcium signaling is a complex process that involves the movement of calcium ions (Ca2+) within and between cells. Calcium ions play a crucial role in many cellular functions, including muscle contraction, neurotransmitter release, gene expression, and cell division. Calcium signaling is regulated by a network of proteins that sense changes in calcium levels and respond by activating or inhibiting specific cellular processes. In the medical field, calcium signaling is important for understanding the mechanisms underlying many diseases, including cardiovascular disease, neurodegenerative disorders, and cancer. Calcium signaling is also a target for many drugs, including those used to treat hypertension, arrhythmias, and osteoporosis. Understanding the complex interactions between calcium ions and the proteins that regulate them is therefore an important area of research in medicine.
In the medical field, an amino acid sequence refers to the linear order of amino acids in a protein molecule. Proteins are made up of chains of amino acids, and the specific sequence of these amino acids determines the protein's structure and function. The amino acid sequence is determined by the genetic code, which is a set of rules that specifies how the sequence of nucleotides in DNA is translated into the sequence of amino acids in a protein. Each amino acid is represented by a three-letter code, and the sequence of these codes is the amino acid sequence of the protein. The amino acid sequence is important because it determines the protein's three-dimensional structure, which in turn determines its function. Small changes in the amino acid sequence can have significant effects on the protein's structure and function, and this can lead to diseases or disorders. For example, mutations in the amino acid sequence of a protein involved in blood clotting can lead to bleeding disorders.
Cyclic AMP-dependent protein kinase (PKA) RIalpha subunit is a regulatory subunit of the PKA enzyme, which is involved in the regulation of various cellular processes, including metabolism, gene expression, and cell proliferation. The PKA enzyme is a heterotetramer composed of two regulatory subunits (RIalpha or RIIalpha) and two catalytic subunits (Calpha or Cbeta). The regulatory subunits bind to and inhibit the catalytic subunits in the absence of the second messenger cyclic AMP (cAMP). When cAMP levels increase, the regulatory subunits are phosphorylated by cAMP-dependent protein kinase A (PKA), which leads to the release of the catalytic subunits and activation of the enzyme. The RIalpha subunit is expressed in a variety of tissues, including the brain, heart, and muscle, and is involved in the regulation of various physiological processes, including muscle contraction, glucose metabolism, and gene expression.
Cyclic AMP-dependent protein kinase type I (PKA-I) is a type of enzyme that plays a crucial role in regulating various cellular processes in the body.

When cAMP levels rise, the regulatory subunits are phosphorylated by other kinases, which releases the catalytic subunits and allows them to phosphorylate their target proteins. PKA-I is involved in a wide range of cellular processes, including metabolism, gene expression, and cell proliferation. It phosphorylates various proteins, including enzymes, transcription factors, and ion channels, to regulate their activity and function. Dysregulation of PKA-I activity has been implicated in various diseases, including cancer, diabetes, and neurological disorders.
Cyclic GMP (cGMP) is a signaling molecule that plays a crucial role in regulating various physiological processes in the body, including smooth muscle contraction, neurotransmission, and blood pressure regulation. It is synthesized from guanosine triphosphate (GTP) by the enzyme guanylate cyclase and is degraded by the enzyme phosphodiesterase. In the medical field, cGMP is often studied in the context of its role in the regulation of blood vessels and the cardiovascular system. For example, cGMP is involved in the dilation of blood vessels, which helps to lower blood pressure and improve blood flow. It is also involved in the regulation of heart rate and contractility. Abnormal levels of cGMP can lead to a variety of medical conditions, including hypertension, heart failure, and erectile dysfunction. In these cases, medications that either increase or decrease cGMP levels may be used to treat the underlying condition.

These enzymes phosphorylate specific amino acids, such as serine and threonine, on target proteins, thereby altering their activity, stability, or localization within the cell. PSTKs are involved in a wide range of diseases, including cancer, diabetes, cardiovascular disease, and neurodegenerative disorders. Therefore, understanding the function and regulation of PSTKs is important for developing new therapeutic strategies for these diseases.
In the medical field, a cell line refers to a group of cells that have been derived from a single parent cell and have the ability to divide and grow indefinitely in culture. These cells are typically grown in a laboratory setting and are used for research purposes, such as studying the effects of drugs or investigating the underlying mechanisms of diseases. Cell lines are often derived from cancerous cells, as these cells tend to divide and grow more rapidly than normal cells. However, they can also be derived from normal cells, such as fibroblasts or epithelial cells. Cell lines are characterized by their unique genetic makeup, which can be used to identify them and compare them to other cell lines. Because cell lines can be grown in large quantities and are relatively easy to maintain, they are a valuable tool in medical research. They allow researchers to study the effects of drugs and other treatments on specific cell types, and to investigate the underlying mechanisms of diseases at the cellular level.
Calmodulin-binding proteins (CaMBPs) are a group of proteins that interact with the calcium-binding protein calmodulin (CaM) in the cell. These proteins play important roles in various cellular processes, including signal transduction, gene expression, and cell division. CaM is a small, ubiquitous protein that is found in all eukaryotic cells. It is composed of two globular domains, each of which can bind to one molecule of calcium. When calcium levels in the cell increase, CaM binds to calcium ions and undergoes a conformational change that allows it to interact with other proteins, including CaMBPs. CaMBPs are a diverse group of proteins that include enzymes, ion channels, and transcription factors. Some examples of CaMBPs include: * Phosphodiesterase 4D (PDE4D): an enzyme that breaks down cyclic AMP (cAMP) in the cell, which is an important second messenger in signal transduction. * Calmodulin-dependent protein kinase II (CaMKII): an enzyme that plays a key role in the regulation of neuronal signaling and learning and memory. * Ryanodine receptor (RyR): a protein that regulates the release of calcium ions from the endoplasmic reticulum in muscle cells. * Calmodulin-dependent transcription activator (CAMTA): a transcription factor that regulates the expression of genes involved in plant development and stress responses. Overall, CaMBPs are important regulators of cellular signaling and function, and their activity is tightly controlled by calcium levels in the cell.
In the medical field, binding sites refer to specific locations on the surface of a protein molecule where a ligand (a molecule that binds to the protein) can attach.

Dysregulation of PI4K activity has been implicated in various diseases, including cancer, neurodegenerative disorders, and immune system dysfunction. Therefore, PI4K is an important target for the development of new therapeutic strategies.
