Sodium-Calcium Exchange in the Hearty several different approaches, including an assessment of thermodynamic driving forces in membrane vesicles (Reeves & Hale, 1984), measurements of exchange currents and their reversal potentials in heart cells (Kimura ..,1987; Lipp & Pott, 1988) and direct flux measurements in the barnacle muscle (

Function and Regulation of Intracellular Ca in Renal Cells., 1985, Shayman et al., 1986, Tang and Weinberg 1986, Taniguchi et al., 1989a and 1989b, Teitelbaum and Berl 1986). Values obtained, range between 70 and 450 nM, with the majority of studies reporting average concentrations of 100 to 200 nM.

Control of Calcium Influx and Internal Calcium Release in Electrically Non-Excitable Cells,4,5) P. is not an independent acute controller of Ca. movement, but modulates the Ins (1,4,5) P.-evoked Ca. mobilization by an unknown mechanism which is only slowly reversible (Petersen, 1989, 1990).

Patch Clamp Study of Ca Channels in Isolated Renal Tubule Segmentsdiated process, or via Ca channels. We have sought the presence of Ca channels in the apical membranes of isolated tubule segments of the rabbit kidney, using the patch clamp technique (9) with barium (Ba) as a charge carrier.

Tertiary Structure of the Muscle Calcium Pumpe functional enzyme may exist as a dimer. In contrast, T. digestion has no influence on ATP-dependent calcium occlusion as measured by Eu. luminescence spectroscopy. The study of the synthetic peptide analogues and their binding characteristics indicate that Asp 196 and Asp 149 are important for cation binding.

The Activity of the Basolateral Membrane Calcium-Pumping ATPase and Intestinal Calcium Transportis still not certain whether the activity of the Ca.pump is regulated in the intestine. Regulation of activity would be expected in different states of Ca. absorption, such as on varying intakes of Ca., or by vitamin D, and in different areas of the small intestine.

,„Rational-choice“: eine Zwischenbilanz,stions about Ca. metabolism in VSM: Is the SR store of Ca. modulated? And if so, how? How is Ca. extruded and Ca. balance maintained? And, how is supra-threshold [Ca.]c and tonic tension maintained in VSM that exhibits tonic contractions? The answers to these questions are essential for understanding how tension is regulated in VSM.

A 19KD C-Terminal Tryptic Fragment of the Alpha Chain of Na/K-ATPase, Essential for Cation Occlusionesicles, to sustain a slow Rb-Rb exchange. Cation occlusion sites and the transport pathway, within trans-membrane segments, are thus quite separate from the ATP binding site, located on the cytoplasmic domain of the alpha chain.
