IQGAP1, a versatile scaffolding protein, critically regulates cytoskeletal organization, cell motility, proliferation, and signaling cascades. Beyond coordinating these cellular functions, it is increasingly recognized as a key driver in malignancies, immune dysfunction, metabolic dysregulation, and cardiovascular pathologies. By binding receptor tyrosine kinases, small GTPases, and downstream effectors, IQGAP1 modulates oncogenesis, immune evasion, and metabolic imbalance, while contributing to chemoresistance. This review synthesizes advances in IQGAP1's structural domains, disease-specific signaling networks, and therapeutic targeting strategies, emphasizing its translational potential in developing precision therapies for cancer, metabolic syndromes, and immune disorders.

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
