    basic FUNCTION
  • Rho GTPase activator activity
  • with DOCK3, NEDD9, WASF2, are key molecules regulating RAC1 and RHO signaling that determine the mode of movement driving melanoma cell metastasis
  • AKT1-dependent regulator of cell motility in response to insulin

    protein
  • interaction of the IL1RAPL1 family of proteins with PTPRD and ARHGAP22 reveals a pathophysiological mechanism of cognitive impairment associated with a novel type of trans-synaptic signaling that regulates excitatory synapse and dendritic spine formation
  • insulin-responsive 14-3-3 binding protein
  • AKT1 substrate that binds 14-3-3 proteins in response to treatment with growth factors involved in cell migration
    • cell & other
    REGULATION
    activated by Rho-kinase signaling, that activates ARHGAP22, and suppresses mesenchymal movement by inactivating RAC1
