Modulations of calcium binding and of energy coupling by the calcium pump of sarcoplasmic reticulum
… activity. It acts as an intracellular sink for calcium during relaxation and releases cav2 + during contraction. This highly differentiated endoplasmic reticulum is a self-contained network with a continuous hollow interior which surrounds each muscle fibril (Fig. 1) (Porter, 1961). The SR is …

Unzipping Amyloid Fibrils: How a Novel Calcium-Binding Protein, NUCB1, Prevents the Formation of Amyloid Fibrils
… a widely expressed multi-domain Ca<sup>2+</sup>-binding protein whose precise physiological and biochemical functions are not well understood. We engineered and heterologously expressed a soluble form of NUCB1 (sNUCB1) and characterized its biophysical and biochemical properties. We show that …

Determination of Calcium Binding to Beta-Casein at Various Ph Values Using the Calcium Murexide Method
Calcium binding to casein affects the formation of casein micelles and the behavior of the casein proteins during processing. Since calcium binding is pH dependent, it is important to understand the binding properties of the non-micellar caseins with calcium ions under the influence of pH. The …

Characterization of XVEF and XvCaM : two calcium-binding proteins isolated from the resurrection plant Xerophyta viscosa
… overlap extension PCR. XVEF codes for a putative calcium-binding protein and sequence analysis indicated that it has a 708 bp ORF corresponding to a protein with a molecular mass of26.95 kDa, has a conserved calcium-binding EF-hand motif, potential phosphorylation sites, a pI of 6.49 and a …

The Impact of Calcium Binding Protein 5 (CaBP5) on Synaptic Vesicle Dynamics in Rod Bipolar Cells in the Retina
<p>Calcium binding protein 5 (CaBP5) is a retina-specific protein, specifically expressed in rod bipolar cells and in type 3 OFF and type 5 ON cone bipolar cells. Rod bipolar cells (RBCs) are essential for rod pathway signaling in the vertebrate retina, and they form ribbon style synapses that …

Classification of Neuronal Nicotinic Acetylcholine Receptors in Rat CA1 Hippocampal Interneuron Subpopulations Defined by Calcium-Binding Protein mRNA Expression
… relative quantitative mRNA expression of three Calcium-binding proteins (CaBPs; calbindin, calretinin, parvalbumin) and eight nicotinic acetylcholine receptor (nAChR) subunits (alpha2-alpha5, alpha7, beta2-beta4) from interneurons from the stratum radiatum or stratum oriens within the CA1 region …

Analysis of multiple calmodulin isoforms in Arabidopsis thaliana
… is in part mediated by fluctuations in cytosolic calcium levels. These fluctuations are found to alter the activity of cellular proteins that are sensitive to the calcium levels. The exact nature of signal transduction from external stimuli through calcium is not known, but variations in …

Biophysical Analysis of S100A12 and the Nucleosome Core Particle
<p>Calcium signaling and chromatin remodeling are fundamental regulatory processes that control protein activity and gene expression, respectively. This thesis investigates the molecular mechanisms by which local ligand binding and structural perturbations propagate allosteric effects across larger …

The Impact of pH on the Structure and Function of Neural Cadherin
… extracellular domains (EC1-EC5) that bind 3 calcium ions between each of the modules. Calcium binding is required for dimerization. N-cadherin is involved in diverse processes including tissue morphogenesis, excitatory synapse formation and dynamics, and metastasis of cancer. During …

Characterization and molecular cloning of sos3: A gene important for salt tolerance and potassium nutrition in higher plants
… B subunit of calcineurin from yeast and neuronal calcium sensor from animals. SOS3 contains three putative EF-hand calcium binding domains and a putative myristoylation motif at its NH₂-terminus. SOS3 binds calcium and is myristoylated in vitro. A mutation in SOS3 that destroys the conserved …

Dissection of the Roles of Synaptotagmins in Calcium Dependent Neurotransmitter Release
… release, which is triggered in response to a calcium influx into the presynaptic cell, caused by the arrival of an action potential. Synaptotagmins (Syts) mediate this calcium-dependent regulation of neurotransmitter release by mechanisms that still remain elusive. Syts have two …

Effects of dietary calcium, phytoestrogen rich diets and estrogen on intestinal calcium transport proteins, egg and eggshell quality in maturing layer hens / Ali Asghar Saki.
… estrogen modulates the proteins associated with calcium transport (eg calcium binding protein, calbindin D28k) in the intestinal tissue during sexual maturation of laying hens. Studies the temporal and spatial expression of estrogen receptors (ER) and calcium binding protein in jejunal tissue. …

Unraveling the mechanism of ADAMTS13 resistance to protease inhibition
… variable loop (G236-S263) (MDTCS-V5), and the calcium-binding loop (R180-R193) (MDTCS-C5). MDTCS-GVC5 was generated to study these features simultaneously. Alpha 2-macrogloublin (A2M), tissue inhibitors of metalloproteinases (TIMPs), and small molecule inhibitor (Marimastat) were used as …

Isolation, characterization and expression of calmodulin genes from carrot and Arabidopsis
Calmodulin is a highly conserved calcium-binding protein universally distributed among eukaryotes. Although the role of calmodulin in regulatory pathways in animals is well characterized, information on similar pathways in plants is limited. To better understand the role of calmodulin in plant …
