Inositol trisphosphate or inositol 1,4,5-trisphosphate abbreviated InsP3 or Ins3P or IP3 is an inositol phosphate signaling molecule. It is made by hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP 2), a phospholipid that is located in the plasma membrane, by phospholipase C …

2017年12月8日 · Third order intercept point (IP3) is a hypothetical point where the power level of third-order harmonics will reach the power level of the fundamental signal. The intercept point is a purely mathematical concept and does not correspond to a …

2012年6月29日 · IP3 is a well-known parameter that gauges linearity in radio frequency (RF) functions and components. This tutorial will use basic math and graphics to explain how IP3 is generated and how its values are linked to essential quantities, such as the input and output powers of a device.

2024年3月4日 · The IP3/DAG signaling pathway is a crucial mechanism within cells that helps regulate various biological processes. It involves the activation of inositol trisphosphate (IP3) and diacylglycerol (DAG), which act as secondary messengers to transmit signals within the cell.

IP3 may refer to: Inositol trisphosphate (IP 3), used for signal transduction in biological cells; Third-order intercept point, in radio telecommunication; IP3 International, a nuclear technology company

IP3 is a nonprofit organization working to create healthy, equitable, sustainable communities that advance well-being now and for future generations. We build capacity for transformative change through movement from community insight to concerted action.

2010年4月27日 · These animated lessons illustrate the steps of inositol 1,4,5-trisphosphate (IP 3) signal transduction pathways (1, 2). These pathways regulate numerous cellular and physiological processes, such as carbohydrate metabolism, gene expression, the menstrual cycle, and the flight-or-fight response. Most eukaryotes have some form of these pathways.

Inositol 1,4,5-trisphosphate receptors (IP 3 Rs), by releasing Ca 2+ from the endoplasmic reticulum (ER) of animal cells, allow Ca 2+ to be redistributed from the ER to the cytosol or other organelles, and they initiate store-operated Ca 2+ entry (SOCE).

Type 3 inositol 1,4,5-triphosphate receptor (IP3R3) is an a tetrameric channel that can mediate the release of Ca 2+ from the endoplasmic reticulum (ER) in response to extracellular stimuli. The gating of IP3R3 is regulated not only by ligands but also by other interacting proteins.

The IP3R [IP3 (inositol 1,4,5-trisphosphate) receptor] is responsible for Ca2+ release from the ER (endoplasmic reticulum). We have been working extensively on the P400 protein, which is deficient in Purkinje-neuron-degenerating mutant mice.
