Summary
Proteolysis, the breakdown of proteins, is a newly identified widespread mechanism that significantly alters ion channel activity. This process profoundly impacts Inositol 1,4,5 trisphosphate receptor function, with implications for health and disease.
Area of Science:
- Molecular Biology
- Cellular Biology
- Biochemistry
Background:
- Ion channels are crucial membrane proteins regulating biological activities.
- Channel function is modulated by various factors including ions, proteins, nucleotides, and phosphorylation.
- Existing knowledge extensively covers these modulation forms.
Purpose of the Study:
- To review and summarize channel proteolysis as a novel mechanism regulating ion channel activity.
- To highlight recent findings on proteolysis's impact on Inositol 1,4,5 trisphosphate receptors.
- To discuss the functional consequences of proteolysis in biological and pathological contexts.
Main Methods:
- Literature review and summarization of existing research on ion channel modulation.
- Analysis of recent studies focusing on proteolysis of ion channels, specifically Inositol 1,4,5 trisphosphate receptors.
- Discussion of the functional and pathological implications derived from the reviewed literature.
Main Results:
- Proteolysis emerges as a widespread and significant mechanism for altering ion channel activity.
- Recent findings demonstrate that proteolysis profoundly affects Inositol 1,4,5 trisphosphate receptor activity.
- This proteolytic regulation has potential functional ramifications in development and disease.
Conclusions:
- Channel proteolysis represents a significant, yet under-recognized, mode of ion channel regulation.
- Understanding proteolysis's role in modulating Inositol 1,4,5 trisphosphate receptors is critical.
- Further research into proteolysis is warranted to elucidate its role in physiological and pathological processes.

91.5K
The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. The ion channels—a class of membrane transport proteins—help maintain this ionic gradient for the smooth functioning of physiological activities such as maintaining cell size and volume, conducting nerve impulses, and gas and nutrient exchange.

8.3K
Ion channels are specialized proteins on the plasma membrane that allow charged ions to pass down their electrochemical gradient. Their main function is to maintain the membrane potential which is critical for cell viability. These channels are either gated or non-gated and can transport more than a thousand ions within milliseconds for the cellular event to occur.
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism....

01:12Mechanically-gated Ion Channels
7.8K
Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...

14.4K
Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...

Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...

5.8K
GPCRs are primarily responsible for our sense of smell, taste, and vision. The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.
