... the peripheral SR by Ca 2+ influx (Ca 2+ -induced Ca 2+ release), and (vii) capacitative Ca 2+ entry in vascular smooth muscle. We present an overview of the physiological and pathological implications of these interactions. 3 07 1996 23 05 1997 24 9 2008 Calcium influx Calcium uptake...

... the same tissue, in partially purified form. Calcium uptake by membrane vesicles increased 30% in the presence of this kinase. This effect was proportional to the kinase concentration, and was blocked by either catalytic subunit inhibitor or by prior boiling of the subunit preparation. Stimulation...

... reticulum fractions to be composed of vesicles. 5’-Nucleotidase, alkaline phosphatase, ouabain-sensitive (Na + +K + )-ATPase and K + -phosphatase, and phosphodiesterase I were concentrated in the plasma membrane fraction. The increase in ATP-dependent calcium uptake in the presence of oxalate was greater...
