  • formin family of actin nucleators
  • CATEGORY regulatory
    SUBCELLULAR LOCALIZATION     plasma membrane
  • localizes to the actin-rich cores of primary macrophage podosomes (pMID: 20617518)
  • basic FUNCTION
  • playing a role in the control of reorganization of the actin cytoskeleton in association with RAC and in the regulation of the signal for cell survival
  • DIAPH2 and FMNL1 mediate the formation of highly elastic F-actin networks as effectively and rapidly as alpha-actinin and filamin
  • is potentially responsible for modifying actin at the macrophage podosome and may be involved in actin cytoskeleton dynamics during adhesion and migration within tissues
  • regulates cellular F-actin levels required to maintain structural integrity of the Golgi complex and lysosomes
  • DIAPH1 and FMNL1 have been implicated in centrosome reorientation to the immunological synapse of T lymphocytes
  • DIAPH1 and FMNL1 are novel regulators of spirochete uptake by human immune cells
  • stimulates leukemia cell proliferation as well as migration, and potentially contributes to leukemogenesis and could act in part through RAC1 regulation
  • upon TCR triggering the INF2 formin, together with the formins DIAPH1 and FMNL1, promotes the formation of a specialized array of stable detyrosinated MT that breaks the symmetrical organization of the T-cell microtubule (MT) cytoskeleton
  • DIAPH2, DAAM1, FMNL1, and FMNL2 were found to be required for myofibrillogenesis, non-redundantly
  • CELLULAR PROCESS cell organization/biogenesis
    a component
    small molecule
  • associating with AKT1
  • after RAC1-dependent activation of FMNL1, SRGAP2 mediates a potent mechanism to limit the duration of RAC1 action and inhibit formin activity during rapid actin dynamics
