The researchers found that puffing activated a mechanosensitive channel protein called TRPV4, which is enriched in the membrane of neuronal axons and allows calcium ions to enter the cell.
«In this current study, we've shown that by opening the TRPV1 channel to allow calcium ions to enter the cell, we can turn on a gene.
Kingsley speculates that in its normal form, the ank protein is a pyrophosphate channel that allows pyrophosphate levels to remain high in cartilage throughout life to prevent calcium phosphate crystal formation in the joint cleft.
The binding of positively charged calcium ions in its vicinity opens the channel and allows negatively charged chloride ions to permeate across the membrane.
NPTX2 causes multiple GluR4 proteins to unite and form a channel into the cell, which allows calcium to flow in.
Coauthor Dr. Stefan Feske, of the New York University School of Medicine Department of Pathology, in 2006 discovered ORAI channels, which open and close to allow calcium into cells.
Researchers have known for decades that some microorganisms, such as single - celled green algae, have proteins that respond to light by opening a channel in the microbe's membranes, allowing the passage of electrically charged ions (such as calcium and sodium).
These events are directed by specialized proteins called ion channels that allow the flow of calcium ions in and out of cells and among cell compartments.
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.
In cells from sick hearts, these channels often don't inactivate properly, allowing for excess sodium entry and a build - up of calcium, which ultimately promotes abnormal heart rate (arrhythmia) and symptoms of heart failure.
Excitable cells, such as skeletal muscle and nerve cells, contain voltage - dependent calcium channels in their cell membranes that allow for rapid changes in calcium concentrations.
It acts by binding to specific receptors and allowing sodium (Na +) or calcium (Ca +) to move into brain cells through channels.
