  • a N terminal leucine-zipper and a highly basic region
  • three MAP kinase phosphorylation sites
  • a proline-rich domain that regulates actin assembly at the cell membrane
  • a C terminal VPH (verproline homology)/WH2 (WASP homology 2) domain, verprolin central acidic (VCA) domain, responsible for binding to and activating the Arp2/3 complex, which in-turn nucleates the formation of new actin filaments
  • SCAR/WAVE family
  • CATEGORY regulatory , structural protein
    SUBCELLULAR LOCALIZATION     intracellular
  • actin cytoskeleton
  • at the interface between the lamellipodial actin meshwork and the membrane
  • PRKACA is localized at the leading edge of membrane protrusions and colocalized with WASF2
  • MAPK1 colocalizes with the WASF2 regulatory complex (WRC) at lamellipodial leading edges and directly phosphorylates two WRC components: WASF2 and ABI1
  • DIAPH1 and WASF2 synergize with BAIAP2 to form filopodia
  • might be retained in the cytoplasm through its association with SKAP2
  • basic FUNCTION
  • acting as a potential regulator of actin cytoskeleton and playing a key role in the induction of actin-based processes
  • required for directed cell migration, angiogenesis and cardiovascular development
  • playing a critical role in actin-based processes downstream of Rac that are essential for cell movement
  • implicated in cancer metastasis
  • implicated in the formation of peripheral ruffles and chemotactic migration
  • with DOCK3, NEDD9, ARHGAP22, are key molecules regulating RAC1 and RHO signaling that determine the mode of movement driving melanoma cell metastasis
  • membrane transport of WASF2 implicated in formation of lamellipodia, the first step during cell migration, and involves actin reassembly
  • involved in lamellipodia formation necessary for epithelial cell migration and invasion
  • regulates membrane protrusions and cell migration by promoting Arp2/3 complex-dependent actin reorganization
  • WASF2 and WASL have parallel pathways to F-actin reorganization and function in human NK cells
  • critical role for WASF2 complex in regulation of cellular signaling and epithelial morphogenesis
  • mediates actin cytoskeletal reorganization and lamellipodia protrusion formation, which are required for cell migration and invasion
  • WAS and WASF2 differ in their dynamics and their associated proteins
  • CELLULAR PROCESS cell organization/biogenesis
    cell communication
  • cell shape control
    signaling signal transduction
    downstream effector molecules involved in the transmission of signals from tyrosine kinase receptors and small GTPases to the actin cytoskeleton
    a component
  • associating with the Arp2/3 complex a nucleating core constituent for actin polymerization in vitro
  • complex ABL1/ABI1/WASF2 as critical pathway for coupling stimulatory signals to actin cytoskeletal remodeling
  • WAVE complex can integrate coincident signals to promote localized actin nucleation during cell motility
  • WASF2-PRKACA complex is potentially localized at membrane protrusions
    small molecule
  • by mediating intensive F-actin accumulation at the sites of cell infiltration, WASF2, WASL, and ENAH are crucial for PI3K-dependent cell invasion induced by PDGFA
  • DIAPH1 and WASF2 are important SH3 domain partners of BAIAP2 involved in filopodial protrusion
  • effect of EXOC7 on actin is mediated by promoting the interaction of the Arp2/3 complex with WASF2, a member of the N-WASP/WAVE family of nucleation promoting factors
  • SKAP2 suppresses actin polymerization and cell migration by inhibiting the interaction between WASF2 and CTTN
  • SKAP2 suppresses potentially the translocation of WASF2 and causes changes in the cell membrane cytoskeleton
  • WASF2 complex regulates breast epithelial morphology by a complex mechanism involving repression of TWIST1 expression and ABL kinase activity
  • CTTN can directly bind WASF2, as well as Arp2/3, and both these interactions are necessary for actin assembly at the zonula adherens (ZA)
  • SH3BP1 specifically inactivating RAC1 and its target WASF2 is required for cell motility, thus regarded as an essential regulator of cancer cell metastasis
  • cell & other
    activated by ABL1 via tyrosine phosphorylation (to promote actin remodeling ABL1 forms the crucial link between these two factors)
    phosphorylation (activation of the WASF2 complex requires simultaneous interactions with prenylated Rac-GTP and acidic phospholipids, as well as a specific state of phosphorylation)
    Other phosphorylation of WASF2 by MAP kinases regulates cell polarity during migration
    ARHGEF7 and GIT1 regulate HGF-induced lamellipodia formation and WASF2 transport
