背景信息

IQGAP1 (IQ motif-containing GTPase-activating protein 1) is a multidomain scaffolding protein that regulates diverse cellular processes, including cytoskeletal dynamics, cell adhesion, and signaling pathways. It interacts with numerous binding partners, such as small GTPases (e.g., Rac1. Cdc42), calmodulin, β-catenin, and components of the microtubule network, acting as a molecular hub to coordinate cellular responses to extracellular cues. Structurally, IQGAP1 contains multiple functional domains: a calponin homology domain (CHD) for actin binding, a WW domain for protein-protein interactions, a GTPase-activating protein (GAP)-related domain (GRD) that modulates GTPase activity, and IQ motifs that bind calmodulin. Despite its name, IQGAP1 lacks intrinsic GAP activity but instead stabilizes GTP-bound forms of Rac1 and Cdc42. promoting their downstream effects.

Recombinant IQGAP1 proteins are engineered for in vitro studies to dissect its molecular interactions and functional roles. These proteins are typically expressed in bacterial or mammalian systems, purified via affinity tags, and validated for structural integrity. Researchers utilize recombinant IQGAP1 to investigate its role in pathological conditions, such as cancer metastasis (by enhancing cell migration/invasion), inflammation (via MAPK/ERK pathway modulation), and neurological disorders. Its dysregulation is linked to tumor progression, making it a potential therapeutic target. Recombinant variants, including domain-deletion mutants or phospho-mimetic forms, help map binding interfaces and signaling mechanisms. Studies using these tools have revealed IQGAP1’s capacity to crosslink actin filaments, influence cell polarity, and mediate crosstalk between Wnt and growth factor signaling. Ongoing research aims to develop inhibitors targeting IQGAP1 interactions for therapeutic applications.
