Intracellular signaling cascades Department of Biological Regulation Rony Seger 3602 4116 rony.seger@weizmann.ac.il Intracellular signaling cascades are the main routes of communication between the plasma membrane and regulatory targets in various intracellular compartments. Mitogen-activated Current Topics in Behavioral Neurosciences. pp 1-32 | Cite as. Intracellular Signaling Cascades in Bipolar Disorder This article reviews the current intracellular signaling cascades in photobiology and photomedicine under the influence of red to NIR light on mammalian cells. Specifically, mitochondrial retrograde signaling initiated by cytochrome c oxidase photomodulation is discussed in detail in the treatment of indications using LLLT, such as vitiligo management, retinal protection, and tumor therapy. The effectiveness of the intracellular regulation is affected strongly by the characteristics of signal propagation through the cascade. For signals that are amplified as they propagate through the cascade, reactions in the upstream levels of the cascade exhibit much larger sensitivities to regulation by release of phosphorylated substrate protein and kinase than downstream reactions.

Intracellular signaling cascade

Intracellular signaling cascades amplify a signal originating extracellularly and directs it to its intended intracellular target resulting in transcription, translation, protein modifications, enzyme activation, cellular metabolism, mitosis, and/or apoptosis. The most basic of signaling cascades involves the activation of second messengers and the release of kinases. These communications between cells triggers intracellular signaling cascades, termed signal transduction pathways, that regulate specific cellular functions. Each signal transduction occurs with a primary extracellular messenger that binds to a transmembrane or nuclear receptor, initiating intracellular signals. The effectiveness of the intracellular regulation is affected strongly by the characteristics of signal propagation through the cascade. For signals that are amplified as they propagate through the cascade, reactions in the upstream levels of the cascade exhibit much larger sensitivities to regulation by release of phosphorylated substrate protein and kinase than downstream reactions.

The activated targets promote cell growth and division. Together, Raf, MEK, and the ERKs make up a three-tiered kinase signaling pathway called a mitogen-activated protein kinase (MAPK) cascade. (A mitogen is a signal that causes cells to undergo mitosis, or divide.)

For signals that are amplified as they propagate through the cascade, reactions in the upstream levels of the cascade exhibit much larger sensitivities to regulation by release of phosphorylated substrate protein and kinase than downstream reactions. The signaling cascade is series of chemical reactions that occur in a cell by a set phosphorylation of kinase enzymes by the intracellular transmitter molecules and are ready to communicate the biochemical information exchanged between the plasma membrane and nucleus.
