Explore the intricacies of cell signaling in this comprehensive 16-minute video lecture on genomic vs non-genomic actions. Delve into the mechanisms of lipid-soluble and water-soluble hormones, G-proteins (Gq, Gs, Gi), and their coupled receptors. Examine the structure and function of transmembrane domains, alpha, beta, and gamma subunits, as well as ligand-gated ion channels. Investigate enzyme-linked receptors, including receptor-tyrosine kinase (RTK) and nonreceptor tyrosine kinase (NRTK). Learn about crucial signaling molecules such as cAMP, cGMP, IP3, DAG, and PIP2. Gain a thorough understanding of cell signaling pathways, including JAK-STAT, and their roles in endocrine physiology.
