PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • N-terminal WH1 domain binds the chaperone, WAS-interacting protein (WIPF1)
  • a GBD domain
  • proline rich protein P21-Rho-binding domain (PBD)also facilitating filament elongation
  • a VCA domain interacting with ARP2/3, and phosphorylation of the VCA domain enhances this interaction, which leads to actin polymerization (Zhang 2009)
  • a conserved aldolase binding motif
  • HOMOLOGY
    interspecies homolog to murine Wasp
    Homologene
    FAMILY (WASP)/WASP-family Verprolin homologous (WAVE) proteins

    basic FUNCTION
  • putatively involved in actin polymerization, cytoskeleton rearrangement and lymphoid signaling in response to external stimuli transmitted by tyrosine kinase receptors and small GTPases
  • playing a role in cell organization
  • controlling in cooperation with CDC42, the podosomes (dynamic actin-containing adhesion structures of primary human macrophage and involved in migratory processes)
  • playing a unique role for peripheral T cell function, but T cell development depends on the combined activity of WAS and WASL
  • involved in signaling and cytoskeletal organization that includes WAS and Scar/WASP-family verprolin homologous (WAVE) proteins (Le Bras 2009)
  • plays a critical role in cellular function by linking surface receptor signaling to actin reorganization (Le Bras 2009)
  • cytoskeletal regulator in hematopoietic cells (Blundell 2009)
  • crucial role in filopodia formation
  • CELLULAR PROCESS cell organization/biogenesis

    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
    a component
  • forming a complex with FBNP1, DNM2, TRIP10 in the early stage of endocytosis
  • complex formation of FNBP1 with WAS, WIPF1, and dynamin-2 at the plasma membrane is critical for the formation of podosomes and phagocytic cups (Tsuboi 2009)
  • interacting with SNX33 through its VCA domain (Zhang 2009)
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • CDC42 and RAC1 to the cytoskeletal regulation of B lymphocytes
  • binding NCK, GRB2 and the GTPase-GTP binding protein CDC42
  • selectively associating with SH3 homology domains
  • interactig with intersection 2 (ITSN2) and CDC42 to link the clathrin endocytosis machinery to WASP-mediated actin polymerization and ultimately to occupancy-induced TCR endocytosis
  • WIRE
  • TGFBR3 is a novel regulator of BAIAP2/WAS via CDC42 to regulate filopodial formation and cell adhesion
  • cell & other
    REGULATION
    activated by CDC42, playing a role in activation of T cells during engagement by antigen-presenting cells
    Other provides a link between CDC42 and the actin cytoskeleton
    regulated by WASPIP (stabilizes WASP and important for its function)
    phosphorylation is a key event in the activation of WAS during many cellular activities (Blundell 2009)
