Cytosolic signaling molecule
WebScience Biology Lipid-soluble signaling molecules, such as testosterone, cross the membrane of all cells but only affect target cells because a. intracellular receptors are only present in target cells b. only target cells possess the cytosolic enzymes that transduce the testosterone c. target cells are the only cells that can initiate the … The resting concentration of Ca in the cytoplasm is normally maintained around 100 nM. This is 20,000- to 100,000-fold lower than typical extracellular concentration. To maintain this low concentration, Ca is actively pumped from the cytosol to the extracellular space, the endoplasmic reticulum (ER), and sometimes into the mitochondria. Certain proteins of the cytoplasm and organe…

WebAbstract: Cytosolic double-stranded DNA (dsDNA) triggers type-I interferon production through the endoplasmic reticulum adaptor protein STING (also known as MITA, MPYS and ERIS), which activates the transcription factor IRF3. However, how STING activates IRF3 remains largely unknown. WebWhich characteristic must a signaling molecule have in order to bind to a cytosolic or nuclear receptor? It must be lipophilic. The binding of lipophilic messengers, such as …
WebA typical cell-surface receptor has three different domains, or protein regions: a extracellular ("outside of cell") ligand-binding domain, a hydrophobic domain extending through the … WebWhen a signaling molecule binds to a G-protein-coupled receptor in the plasma membrane, a GDP molecule associated with the α subunit is exchanged for GTP. The β and γ subunits dissociate from the α subunit, and a cellular response is triggered either by the α subunit or the dissociated β pair. Hydrolysis of GTP to GDP terminates the signal.
WebThe signaling pathways shown below integrate information provided by signal 1 and signal 2 to activate the transcription of a target gene and trigger a cell response. The intracellular …
