This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Gq protein-coupled receptors (GqPCRs) are membrane bound proteins that transmit signals from outside the cell to internal signaling pathways. One of these pathways is the PI3K/AKT pathway, which plays roles in cellular proliferation, survival, metabolism, and differentiation. PI3K/AKT dysregulation is also often implicated in cancers. A previous study determined that activating GqPCRs in certain cells inactivated AKT, which led to a specific type of cell death, JNK-dependent apoptosis. This unique signal seems to play an important role in physiological and pathological events like pituitary development and cardiac hypertrophy. Now, a new study determined that the mechanism of this AKT inactivation relies on another signaling-related protein, PP2A. When the GqPCRs are not activated, a fraction of PP2A "c" subunit is in a dimer complex with another protein, IGBP1 and they are bound to the p85 subunit of PI3K, causing its activation..."
