Regulation of Ca2+ release from the ryanodine receptor of sarcoplasmic reticulum.

G H O'Sullivan et al.

Biochemical Society transactions, 23(2), 358S-358S (1995-05-01)

An exposed carboxyl group on sialic acid is essential for gangliosides to inhibit calcium uptake via the sarco/endoplasmic reticulum Ca2+-ATPase: relevance to gangliosidoses.

Luba Ginzburg et al.

Journal of neurochemistry, 104(1), 140-146 (2008-01-05)

We previously observed that gangliosides GM2, GM1, and GM3 inhibit Ca2+-uptake via the sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) in neurons and in brain microsomes. We now systematically examine the effect of various gangliosides and their analogs on Ca2+-uptake via SERCA and

Effects of gallopamil on calcium release and intramembrane charge movements in frog skeletal muscle fibres.

D Feldmeyer et al.

The Journal of physiology, 421, 343-362 (1990-02-01)

1. Intramembrane charge movements and changes in intracellular Ca2+ concentration were studied in voltage clamp experiments on cut twitch muscle fibres of the frog. The restoration from inactivation caused by steady depolarization and its modification by the phenylalkylamine Ca2+ channel

Mn2+ transport across biological membranes may be monitored spectroscopically using the Ca2+ indicator dye antipyrylazo III.

C E Gavin et al.

Analytical biochemistry, 192(1), 44-48 (1991-01-01)

The metallochromic indicator antipyrylazo III can be used for the rapid and convenient monitoring of Mn2+ transport in biological systems. The apparent KD of the Mn-antipyrylazo III complex in buffered 150 mM KCl (pH 7.2 at 20 degrees C) is

Simultaneous monitoring of changes in magnesium and calcium concentrations in frog cut twitch fibers containing antipyrylazo III.

M Irving et al.

The Journal of general physiology, 93(4), 585-608 (1989-04-01)

Antipyrylazo III was introduced into frog cut twitch fibers (17-19 degrees C) by diffusion. After action potential stimulation, the change in indicator absorbance could be resolved into two components that had different time courses and wavelength dependences. The first component
