Phosphorylation of type-1 inositol 1,4,5-trisphosphate receptors by cyclic nucleotide-dependent protein kinases: a mutational analysis of the functionally important sites in the S2+ and S2- splice variants. (2/7)

Inositol 1,4,5-trisphosphate receptors (InsP3R) are the major route of intracellular calcium release in eukaryotic cells and as such are pivotal for stimulation of Ca2+-dependent effectors important for numerous physiological processes. Modulation of this release has important consequences for defining the particular spatio-temporal characteristics of Ca2+ signals. In this study, regulation of Ca2+ release by phosphorylation of type-1 InsP3R (InsP3R-1) by cAMP (PKA)- and cGMP (PKG)-dependent protein kinases was investigated in the two major splice variants of InsP3R-1. InsP3R-1 was expressed in DT-40 cells devoid of endogenous InsP3R. In cells expressing the neuronal, S2+ splice variant of the InsP3R-1, Ca2+ release was markedly enhanced when either PKA or PKG was activated. The sites of phosphorylation were investigated by mutation of serine residues present in two canonical phosphorylation sites present in the protein. Potentiated Ca2+ release was abolished when serine 1755 was mutated to alanine (S1755A) but was unaffected by a similar mutation of serine 1589 (S1589A). These data demonstrate that Ser-1755 is the functionally important residue for phosphoregulation by PKA and PKG in the neuronal variant of the InsP3R-1. Activation of PKA also resulted in potentiated Ca2+ release in cells expressing the non-neuronal, S2- splice variant of the InsP3R-1. However, the PKA-induced potentiation was still evident in S1589A or S1755A InsP3R-1 mutants. The effect was abolished in the double (S1589A/S1755A) mutant, indicating both sites are phosphorylated and contribute to the functional effect. Activation of PKG had no effect on Ca2+ release in cells expressing the S2- variant of InsP3R-1. Collectively, these data indicate that phosphoregulation of InsP3R-1 has dramatic effects on Ca2+ release and defines the molecular sites phosphorylated in the major variants expressed in neuronal and peripheral tissues.

Ca(2+)-dependent conformational changes in guanylyl cyclase-activating protein 2 (GCAP-2) revealed by site-specific phosphorylation and partial proteolysis. (3/7)

Guanylyl cyclase-activating proteins (GCAPs) are calcium sensor proteins of the EF-hand superfamily that inhibit retinal photoreceptor membrane guanylyl cyclase (retGC) in the dark when they bind Ca(2+) but activate retGC when Ca(2+) dissociates from GCAPs in response to light stimulus. We addressed the difference in exposure of GCAP-2 structure to protein kinase and a protease as indicators of conformational change caused by binding and release of Ca(2+). We have found that unlike its homolog, GCAP-1, the C terminus of GCAP-2 undergoes phosphorylation by cyclic nucleotide-dependent protein kinases (CNDPK) present in the retinal extract and rapid dephosphorylation by the protein phosphatase PP2C present in the retina. Inactivation of the CNDPK phosphorylation site in GCAP-2 by substitutions S201G or S201D, as well as phosphorylation or thiophosphorylation of Ser(201), had little effect on the ability of GCAP-2 to regulate retGC in reconstituted membranes in vitro. At the same time, Ca(2+) strongly inhibited phosphorylation of the wild-type GCAP-2 by retinal CNDPK but did not affect phosphorylation of a constitutively active Ca(2+)-insensitive GCAP-2 mutant. Partial digestion of purified GCAP-2 with Glu-C protease revealed at least two sites that become exposed or constrained in a Ca(2+)-sensitive manner. The Ca(2+)-dependent conformational changes in GCAP-2 affect the areas around Glu(62) residue in the entering helix of EF-hand 2, the areas proximal to the exiting helix of EF-hand 3, and Glu(136)-Glu (138) between EF-hand 3 and EF-hand 4. These changes also cause the release of the C-terminal Ser(201) from the constraint caused by the Ca(2+)-bound conformation. (+info)

KMUP-1 activates BKCa channels in basilar artery myocytes via cyclic nucleotide-dependent protein kinases. (4/7)

This study investigated whether KMUP-1, a synthetic xanthine-based derivative, augments the delayed-rectifier potassium (K(DR))- or large-conductance Ca2+-activated potassium (BKCa) channel activity in rat basilar arteries through protein kinase-dependent and -independent mechanisms. Cerebral smooth muscle cells were enzymatically dissociated from rat basilar arteries. Conventional whole cell, perforated and inside-out patch-clamp electrophysiology was used to monitor K+- and Ca2+ channel activities. KMUP-1 (1 microM) had no effect on the K(DR) current but dramatically enhanced BKCa channel activity. This increased BKCa current activity was abolished by charybdotoxin (100 nM) and iberiotoxin (100 nM). Like KMUP-1, the membrane-permeable analogs of cGMP (8-Br-cGMP) and cAMP (8-Br-cAMP) enhanced the BKCa current. BKCa current activation by KMUP-1 was markedly inhibited by a soluble guanylate cyclase inhibitor (ODQ 10 microM), an adenylate cyclase inhibitor (SQ 22536 10 microM), competitive antagonists of cGMP and cAMP (Rp-cGMP, 100 microM and Rp-cAMP, 100 microM), and cGMP- and cAMP-dependent protein kinase inhibitors (KT5823, 300 nM and KT5720, 300 nM). Voltage-dependent L-type Ca2+ current was significantly suppressed by KMUP-1 (1 microM), and nearly abolished by a calcium channel blocker (nifedipine, 1 microM). In conclusion, KMUP-1 stimulates BKCa currents by enhancing the activity of cGMP-dependent protein kinase, and in part this is due to increasing cAMP-dependent protein kinase. Physiologically, this activation would result in the closure of voltage-dependent calcium channels and the relaxation of cerebral arteries. (+info)

Osmotic regulation of betaine homocysteine-S-methyltransferase expression in H4IIE rat hepatoma cells. (5/7)

Cell hydration changes critically affect liver metabolism and gene expression. In the course of gene expression studies using nylon cDNA-arrays we found that hyperosmolarity (405 mosmol/l) suppressed the betaine-homocysteine methyltransferase (Bhmt) mRNA expression in H4IIE rat hepatoma cells. This was confirmed by Northern blot and real-time quantitative RT-PCR analysis, which in addition unraveled a pronounced induction of Bhmt mRNA expression by hypoosmotic (205 mosmol/l) swelling. Osmotic regulation of Bhmt mRNA expression was largely paralleled at the levels of Bhmt protein and enzymatic activity. Like hyperosmotic NaCl, hyperosmotic raffinose but not hyperosmotic urea suppressed Bhmt mRNA expression, suggesting that cell shrinkage rather than increased ionic strength or hyperosmolarity per se is the trigger. Hypoosmolarity increased the expression of a reporter gene driven by the entire human BHMT promoter, whereas destabilization of BHMT mRNA was observed under hyperosmotic conditions. Osmosensitivity of Bhmt mRNA expression was impaired by inhibitors of tyrosine kinases and cyclic nucleotide-dependent kinases. The osmotic regulation of BHMT may be part of a cell volume-regulatory response and additionally lead to metabolic alterations that depend on the availability of betaine-derived methyl groups.

Cyclic AMP-dependent protein kinases (also known as cAMP-dependent protein kinases or PKA) are a family of enzymes that play a crucial role in regulating various cellular processes in the body. These enzymes are activated by the presence of cyclic AMP (cAMP), a second messenger molecule that is produced in response to various stimuli, such as hormones, neurotransmitters, and growth factors. PKA is a heterotetrameric enzyme composed of two regulatory subunits and two catalytic subunits. The regulatory subunits bind to cAMP and prevent the catalytic subunits from phosphorylating their target proteins. When cAMP levels rise, the regulatory subunits are activated and release the catalytic subunits, allowing them to phosphorylate their target proteins.

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.

Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are a type of ion channel found in the cell membranes of various types of neurons and cardiac cells. These channels are unique in that they are activated by hyperpolarization, which is an increase in the electrical potential across the cell membrane, rather than depolarization, which is a decrease in the electrical potential. HCN channels are permeable to both potassium and sodium ions, but they are more selective for potassium ions. When the cell membrane becomes hyperpolarized, the HCN channels open, allowing potassium ions to flow into the cell. This influx of potassium ions further hyperpolarizes the cell membrane, creating a positive feedback loop that can lead to the generation of electrical signals in the cell. In neurons, HCN channels play a role in the generation of slow-wave activity, which is important for sleep and other rhythmic behaviors. In cardiac cells, HCN channels are involved in the generation of the electrical signals that control heart rate and contractility.

Cyclin-dependent kinase inhibitor p27 (p27Kip1) is a protein that plays a role in regulating cell cycle progression. It is a member of the Cip/Kip family of cyclin-dependent kinase inhibitors, which also includes p21 and p57. In the cell cycle, the progression from one phase to the next is tightly regulated by a series of events that involve the activity of cyclin-dependent kinases (CDKs). CDKs are enzymes that are activated by binding to specific cyclins, which are proteins that are synthesized and degraded in a cyclic manner throughout the cell cycle. When CDKs are activated, they phosphorylate target proteins, which can either promote or inhibit cell cycle progression. p27Kip1 acts as a CDK inhibitor by binding to and inhibiting the activity of CDKs. It is primarily expressed in cells that are in a non-dividing state, such as terminally differentiated cells and quiescent cells. In these cells, p27Kip1 helps to maintain the cell in a non-dividing state by inhibiting the activity of CDKs, which prevents the cell from entering the cell cycle. In contrast, p27Kip1 is downregulated or lost in many types of cancer cells, where it is often associated with increased cell proliferation and tumor growth. This suggests that p27Kip1 may play a role in the development and progression of cancer.

Heterotrimeric GTP-binding proteins, also known as G proteins, are a family of proteins that play a crucial role in signal transduction in cells. They are composed of three subunits: an alpha subunit, a beta subunit, and a gamma subunit. When a signaling molecule, such as a hormone or neurotransmitter, binds to a cell surface receptor, it causes a conformational change in the receptor that leads to the activation of a G protein. The alpha subunit then exchanges GDP (guanosine diphosphate) for GTP (guanosine triphosphate) and dissociates from the beta and gamma subunits. The alpha subunit then binds to and activates an effector protein, such as an enzyme or ion channel, leading to a cellular response. The beta and gamma subunits remain associated and can be recycled to form a new G protein complex. The G protein cycle is tightly regulated and allows cells to respond to a wide range of signaling molecules with precision and specificity. Heterotrimeric G proteins are involved in many physiological processes, including muscle contraction, neurotransmitter release, and the regulation of blood pressure. Mutations in G protein genes can lead to a variety of diseases, including hypertension, diabetes, and neurological disorders.

Therefore, it is important to use quinolones only as directed by a healthcare provider and to report any side effects that occur.

In the medical field, neoplasms refer to abnormal growths or tumors of cells that can occur in any part of the body. These growths can be either benign (non-cancerous) or malignant (cancerous). Benign neoplasms are usually slow-growing and do not spread to other parts of the body. They can cause symptoms such as pain, swelling, or difficulty moving the affected area. Examples of benign neoplasms include lipomas (fatty tumors), hemangiomas (vascular tumors), and fibromas (fibrous tumors). Malignant neoplasms, on the other hand, are cancerous and can spread to other parts of the body through the bloodstream or lymphatic system. They can cause a wide range of symptoms, depending on the location and stage of the cancer. Examples of malignant neoplasms include carcinomas (cancers that start in epithelial cells), sarcomas (cancers that start in connective tissue), and leukemias (cancers that start in blood cells). The diagnosis of neoplasms typically involves a combination of physical examination, imaging tests (such as X-rays, CT scans, or MRI scans), and biopsy (the removal of a small sample of tissue for examination under a microscope). Treatment options for neoplasms depend on the type, stage, and location of the cancer, as well as the patient's overall health and preferences.

They are also being studied as potential targets for the development of new treatments for these conditions.

Oligoribonucleotides are short chains of ribonucleotides, which are the building blocks of RNA. They are typically composed of 5 to 20 ribonucleotides and are often used in medical research and therapy as tools to manipulate gene expression or to study the function of RNA molecules. In the medical field, oligoribonucleotides are used in a variety of applications, including: 1. Gene silencing: Oligoribonucleotides can be designed to bind to specific RNA molecules and prevent their translation into proteins, thereby silencing the expression of the corresponding gene. 2. RNA interference (RNAi): Oligoribonucleotides can be used to induce RNAi, a natural process in which small RNA molecules degrade complementary messenger RNA (mRNA) molecules, leading to the suppression of gene expression. 3. Therapeutic applications: Oligoribonucleotides are being investigated as potential therapeutic agents for a variety of diseases, including cancer, viral infections, and genetic disorders. 4. Research tools: Oligoribonucleotides are commonly used as research tools to study the function of RNA molecules and to investigate the mechanisms of gene regulation. Overall, oligoribonucleotides are a versatile and powerful tool in the medical field, with a wide range of potential applications in research and therapy.

Insulin-like Growth Factor I (IGF-I) is a protein hormone that plays a crucial role in regulating growth and development in humans and other animals. It is produced by the liver, as well as by other tissues such as the kidneys, muscles, and bones. IGF-I has insulin-like effects on cells, promoting the uptake of glucose and the synthesis of proteins. It also stimulates the growth and differentiation of various cell types, including muscle cells, bone cells, and cartilage cells. In the medical field, IGF-I is often used as a diagnostic tool to measure growth hormone (GH) levels in patients with growth disorders or other conditions that affect GH production. It is also used as a treatment for certain conditions, such as growth hormone deficiency, Turner syndrome, and short stature. However, excessive levels of IGF-I have been linked to an increased risk of certain cancers, such as colon cancer and breast cancer, and it is therefore important to monitor IGF-I levels carefully in patients with these conditions.

In the medical field, a chick embryo refers to a fertilized egg of a chicken that has been incubated for a certain period of time, typically between 4 and 21 days, until it has developed into an embryo. Chick embryos are commonly used in scientific research as a model system for studying developmental biology, genetics, and other areas of biology. They are particularly useful for studying the early stages of development, as they can be easily manipulated and observed under a microscope. Chick embryos are also used in some medical treatments, such as in the development of new drugs and therapies.

Interleukin-6 (IL-6) is a cytokine, a type of signaling molecule that plays a crucial role in the immune system. It is produced by a variety of cells, including immune cells such as macrophages, monocytes, and T cells, as well as non-immune cells such as fibroblasts and endothelial cells. IL-6 has a wide range of functions in the body, including regulating the immune response, promoting inflammation, and stimulating the growth and differentiation of immune cells. It is also involved in the regulation of metabolism, bone metabolism, and hematopoiesis (the production of blood cells). In the medical field, IL-6 is often measured as a marker of inflammation and is used to diagnose and monitor a variety of conditions, including autoimmune diseases, infections, and cancer. It is also being studied as a potential therapeutic target for the treatment of these conditions, as well as for the management of chronic pain and other conditions.

Eye proteins are proteins that are found in the eye and play important roles in maintaining the structure and function of the eye. These proteins can be found in various parts of the eye, including the cornea, lens, retina, and vitreous humor. Some examples of eye proteins include: 1. Collagen: This is a protein that provides strength and support to the cornea and lens. 2. Alpha-crystallin: This protein is found in the lens and helps to maintain its shape and transparency. 3. Rhodopsin: This protein is found in the retina and is responsible for vision in low light conditions. 4. Vitreous humor proteins: These proteins are found in the vitreous humor, a clear gel-like substance that fills the space between the lens and the retina. They help to maintain the shape of the eye and provide support to the retina. Disruptions in the production or function of these proteins can lead to various eye diseases and conditions, such as cataracts, glaucoma, and age-related macular degeneration. Therefore, understanding the structure and function of eye proteins is important for the development of effective treatments for these conditions.
