Harnessing cell death - Lab News

Cellular response following IP3R opening depends on the amount of calcium released through the channel. For instance, small oscillatory calcium concentration elevation promotes cell survival while sustained robust calcium concentration elevation ...

No food, yet larvae reach within and develop - The Hindu

One of the pathways activated by this is the IP3R (Inositol1,4,5-trisphosphate receptor) Ca2+ signalling pathway. IP3R acts by releasing calcium ions from the endoplasmic reticulum within the cell. This takes the level of calcium ions in the cells much ...

Atomic structure reveals how cells translate environmental signals - Science Daily

The determination of the architecture of the Inositol Tris-Phosphate Receptor (IP3R) had long been considered a major goal in biomedical research because of its strategic role inside cells as a molecular train station for transferring signals that ...

Turn left! How myosin-Va helps direct neuron growth - Science Daily

Date: April 28, 2016; Source: RIKEN; Summary: A protein complex that helps direct the growth of axons -- the parts of neurons that make up our nerves, connecting our senses and muscles to the brain and spinal cord -- has been discovered by a team of ...

Biochemists uncover structure of cellular memory mechanism - Phys.Org

New atomic scale images of the structure of calcium's gatekeeper, IP3R, could go a long way toward solving this mystery and lead to treatments for the many diseases tied to channel malfunctions. The IP3R channel was imaged by scientists in the ...

UCI researchers find biomarker for autism that may aid diagnostics - UCI News

This IP3R functional defect was located in the endoplasmic reticulum, which is among the specialized membrane compartments in cells called organelles, and may underpin cognitive impairments – and possibly digestive and immune problems – associated ...

IP3R deficit underlies loss of salivary fluid secretion in Sjögren's Syndrome - Nature.com

Treatment of salivary glands from healthy individuals with LT α, a cytokine linked to disease progression in SS and IL14α mice, reduced Ca2+ signaling. Together, our findings reveal novel IP3R deficits in acinar cells that underlie secretory ...

Stress unleashes the DoGs - Nature.com

Treatment of cells with inhibitors that target any of these proteins prevented DoG induction after KCl treatment, demonstrating that induction of DoGs by osmotic stress requires the IP3R-mediated release of Ca2+ and activation of CaMKII or PKC and PKD.

Gene behind sweating disorder detected - Zee News

Opening of the IP3R channel releases calcium, triggering essential cell behaviour such as movement and secretion, noted the study. A single nucleotide change in the DNA code resulted in a change in protein structure impeding the ability of the channel ...

Scientists unravel the mystery of a rare sweating disorder - Medical Xpress

Opening of the IP3R channel releases calcium, triggering essential cell behaviors such as movement, shape changes, or secretion. In order to understand how the mutation caused a lack of sweat production, Dr. Dahl sought collaboration with Dr. Mikoshiba ...

Role of calcium in familial Alzheimer's disease clarified, pointing to new therapeutics - Science Daily (press release)

The two proteins, called PS1 and PS2 (presenilin 1 and 2), interact with a calcium release channel, the inositol trisphosphate receptor (IP3R), in the endoplasmic reticulum. Mutant PS1 and PS2 increase the activity of the IP3R, in turn increasing ...

Stop antivaxxers. Now. - Discover Magazine (blog)

THI and Ry, in combination, produced additive effects leading to uncoupling of IP3R and RyR1 signals. THI altered ATP-mediated IL-6 secretion, initially enhancing the rate of but suppressing overall cytokine secretion in DCs. DCs are exquisitely ...

Inositol trisphosphate receptor is a membrane glycoprotein complex acting as a Ca2+ channel activated by inositol trisphosphate . InsP3R is very diverse among organisms, and is necessary for the control of cellular and physiological processes including cell division, cell proliferation, apoptosis, fertilization, development, behavior, learning and memory. Inositol triphosphate receptor represents a dominant second messenger leading to the release of Ca2+ from intracellular store sites. There is strong evidence suggesting that the InsP3R plays an important role in the conversion of external stimuli to intracellular Ca2+ signals characterized by complex patterns relative to both space and time. For example, Ca2+ waves and oscillations. The InsP3 receptor was first purified from rat cerebellum by neuroscientists Surachai Supattapone and Solomon Snyder at Johns Hopkins University School of Medicine.
