This might be because adaptor molecules like RhoH and SLP76 can affect the signaling events downstream of calcium release from the ER, or might indicate the existence for a possible positive feedback pathway
from calcium signaling to the upstream of adaptor molecules.

Toshihiro Sassa and Takashi Murayama, the first and second authors of the paper, respectively, say, «we would like to identify the other genes involved in downstream
signaling from this
calcium channel to understand how the
signal leads to aversion to high pH.» Sensing alkaline environments is only the first step; the worm must then quickly react to the stimulus by moving away.
Latest research
from the National Centre for Biological Sciences (NCBS, Bangalore), now shows that maintaining
Calcium balance in cells is also needed for another purpose — it may be regulating the levels of an important
signalling molecule called dopamine in the brain.

Calcium signalling.
In this study, the team, which included Dr. Meerim Nurbaeva and Miriam Eckstein in Dr. Lacruz's lab, for the first time used freshly dissected enamel cells (ameloblasts)
from rodent teeth to modulate physiological processes in order to understand the contribution of CRAC channels in enamel
calcium signaling.
The researchers discovered T - type channels in the pond snail, Lymnaea stagnalis, can shift
from using
calcium ions to using sodium ions to generate the electrical
signal.
The researchers discovered T - type channels in the pond snail, Lymnaea stagnalis, can shift
from using
calcium ions to using sodium ions to generate the electrical
signal because of an outer shield of amino acids called a turret situated above the channel's entrance.
Visualization revealed that
calcium signals occur systemically and wander
from attacked to neighboring leaves within a short period of time, and ultimately put the whole plant into a state of defense readiness.
«Surprisingly, we found that
calcium avoidance occurred through two mechanisms: activation of a unique class of GRNs, distinct
from those that sense bitter compounds and which cause a stop - feeding
signal when activated.
The researchers studied
calcium channels in neurons, which allow for the transport of
calcium ions
from one nerve cell to another, helping the cells transmit itch
signals from the skin to other cells in the spinal cord.
The researchers also identified the molecular mechanisms — particularly the role of
signals from calcium ions — involved in this effect.
The researchers used two - photon
calcium imaging and patch - clamp electrophysiology, two sophisticated technologies that allowed the researchers to record the
signals from individual brain cells.

calcium ion
signaling in release of Chlamydia
from infected cells.»
Nicotinic cholinergic
signaling in hippocampal astrocytes involves
calcium - induced
calcium release
from intracellular stores.
Rothman and Scheller collaborated and proposed that NSF and SNAP form part of the vesicle fusion machinery in neurons, and that synaptotagmin served as a clamp which prevented the fusion process
from happening until a
calcium signal arrived.
Muscle strength, appropriate blood clotting, regular heartbeats, inter-cell communication, and transmission of
signals from one nerve to another are vital processes that also need
calcium.
