Learn about G-protein coupled receptor (GPCR) signaling pathways and their distinct subclasses in this comprehensive 18-minute educational video. Explore the three major GPCR signaling pathways including Gα, Gq, and Gi pathways, understanding how each subclass functions and is regulated within cellular communication systems. Discover the molecular mechanisms behind GPCR activation, the role of different G-protein subunits, and how these pathways control various cellular processes. Examine the structural features that distinguish each GPCR subclass and analyze the downstream signaling cascades they initiate. Master the regulatory mechanisms that control GPCR signaling intensity and duration, including receptor desensitization and internalization processes. Gain insights into how GPCR dysfunction relates to various diseases and understand the therapeutic importance of these signaling pathways in modern medicine.
