    Scientific background

    IQGAP1 is a 190 kDa (1657 amino acid) protein that is ubiquitously expressed and contains six distinct protein-interacting domains with six coiled coil regions1.

    The Ras GTPase-activating-like protein is a scaffold protein involved in regulating various cellular processes; from organizing the actin cytoskeleton, transcription, cell adhesion, and regulating the cell cycle2,3.

    IQGAP1 binds to activated CDC42 but does not stimulate its GTPase activity and it may have a role in cell cycle progression following DNA damage1,2. The protein also regulates NR2A NMDA receptor signaling where it influences cognitive processes4. It also regulates MAPK and Wnt/β-catenin signaling pathways5. It is thought to contribute to tumorigenesis by stimulating cell motility and invasion6.
