An alpha-catulin homologue controls neuromuscular function through localization of the dystrophin complex and BK channels in Caenorhabditis elegans. [PDF]
The large conductance, voltage- and calcium-dependent potassium (BK) channel serves as a major negative feedback regulator of calcium-mediated physiological processes and has been implicated in muscle dysfunction and neurological disorders.

Activation of Calcium Channels
Activation of Ca channels has been described as a Hodgkin-Huxley process in which the time constants have ratios of two or greater (1, 2, 3) or as a three-state linear sequential process with two very different time constants (4). We examined activation by measuring the turn-on and turn-off of macroscopic Ca currents and the discharge of single Ca ...

Vacuolar calcium channels [PDF]
The central vacuole is the largest Ca2+ store in a mature plant cell. Ca2+ release from this store contributes to Ca2+-mediated intracellular signalling in a variety of physiological responses. However, the routes for vacuolar Ca2+ release are not well characterized.

43. Calmodulin regulating calcium sensitivity of Na channels
By extrapolating information from existing research and observing previous assumptions regarding the structure of the Na Channel, this experiment was conducted under the hypothesis that the Na Channel is in part regulated by the calmodulin protein, as a ...

Calcium channels for endocytosis [PDF]
Exocytosis and endocytosis need to be tightly balanced to keep cell surface area constant. This is of particular relevance for presynaptic terminals, where endocytosis needs to compensate for the ongoing exocytosis of synaptic vesicle to ultimately guarantee reliable synaptic transmission.

Cortisol modulates calcium release-activated calcium channel gating in fish hepatocytes
Glucocorticoids (GCs) are rapidly released in response to stress and play an important role in the physiological adjustments to re-establish homeostasis.

Developmental changes in voltage-gated calcium channel α(2)δ-subunit expression in the canine dorsal root ganglion [PDF]
The voltage-gated calcium channel subunit (128 plays a fundamental role in propagation of excitatory signals associated with release of glutamate and neuropeptides substance P (SP) and calcitonin gene-related protein (CGRP).

Although calcium influx triggers endocytosis at many synapses and non-neuronal secretory cells, the identity of the calcium channel is unclear. The plasma membrane voltage-dependent calcium channel (VDCC) is a candidate, and it was recently proposed that

Tuned calcium entry through voltage-gated calcium channels is a key requirement for many cellular functions. This is ensured by channel gates which open during membrane depolarizations and seal the pore at rest. The gating process is determined by distinct sub-processes: movement of voltage-sensing domains (charged S4 segments) as well as opening and ...

Postnatal development of dendritic calcium signaling in rat hippocampal pyramidal cells [PDF]
In CA1 pyramidal neurons, dendritic calcium transients in stratum radiatum were evoked in acute slices via backpropagating action potentials using patch clamp recordings.
