    PROTEIN
    PHYSICAL PROPERTIES
    STRUCTURE
    motifs/domains
  • two domains in the N-terminal half, a coiled-coil domain and a helical domain-that independently bound to F-actin and cooperatively bundled F-actin (pMID: 23979715)
  • an actin-binding domain, which causes the same rearrangements in the cytoskeleton as the full-length protein

    text
  • postsynaptic localization of drebrin depended on actin cytoskeleton organization in both GABAergic and glutamatergic neurons
  • basic FUNCTION
  • involved in neuronal growth
  • may be playing some role in cell migration, extension of neuronal processes and plasticity of dendrites
  • may be invoved in dendritic-cytoskeleton modulation at synapses
  • may affect spine dynamics, vesicle transport, and other myosin-V-driven motility in neurons through attenuating the interaction between actin and myosin-V
  • might regulate dendritic spine morphology via regulation of actin cytoskeleton remodeling and dynamics
  • plays an indispensable role in some processes of generating fear learning and memory
  • involved in the regulation of actin filament organisation, especially during the formation of neurites and cell protrusions of motile cells
  • filament-binding protein involved in organizing the dendritic pool of actin
  • actin filament (F-actin)-binding protein with crucial roles in neuritogenesis and synaptic plasticity

    small molecule
    protein
  • actin binding
  • interacting with NPAS4
  • targets MAPRE3 to coordinate F-actin–microtubule interactions that underlie neuritogenesis
  • decreased the Mg-ATPase activity of myosin V
  • interactions between DBN and RAS regulate dendritic spine plasticity
  • competition between drebrin and several other F-actin-binding proteins
  • DBN1, SETMAR, HILPDA, are direct targets of the SOX11 protein (are direct transcriptional targets of the SOX11 protein)
  • contains a cryptic F-actin-bundling activity regulated by CDK5 phosphorylation
  • cell & other
