motifs/domains
  • N-terminal 250 aa IRSp53/MIM homology domain (IMD)
  • an actin-binding C-terminal WASP-homology domain 2 (WH2) domain may be involved in cell motility and/or shape)

    basic FUNCTION
  • involved in cytoskeletal organization by sequestering actin monomers
  • both a SHH-responsive gene and a new member of the pathway that modulates GLI responses during growth and tumorigenesis
  • prognostic indicator of disease-free survival in breast cancer patients and demonstrates the ability to play a role in governing the metastatic nature of breast cancer cells
  • required at the basal body of mesenchymal cells for cilia maintenance, SHH responsiveness, and de novo hair follicle formation
  • promotes ciliogenesis by antagonizing Src-dependent phosphorylation of Cortactin
  • involved in the Shh signaling pathway in the developing hair follicle and in basal cell carcinomas of the skin
  • acts as a scaffold protein that interacts with multiple partners to regulate actin dynamics
  • may act as a scaffold protein to activate actin assembly
  • function as a cytoskeletal protein with a role in cancer metastasis
  • tissue-specific regulator of plasma membrane dynamics, whose altered expression levels have been linked to cancer metastasis
  • modulates interplay between the actin cytoskeleton and plasma membrane to promote the maintenance of intercellular contacts in kidney epithelia
  • required for neural fold elevation and apical constriction along with cell polarization and elongation in both the superficial and deep layers of the anterior neural plate
  • enhances the localization of the epidermal growth factor receptor (EGFR) to the plasma membrane
  • MTSS1 positively modulates EGF signaling at low cell densities to promote proliferation and, therefore, may be beneficial for the early stages of primary head and neck squamous carcinoma cells tumor growth

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding to actin monomer and RPTP delta
  • binds to DAAM1 and couples non-canonical Wnt signaling to neural tube closure
  • impacts negatively on EGF signaling and this suggests why it inhibits metastasis
