Anatomical context of Cfl1

  • Taken together, these data suggest that the three biochemically distinct mammalian ADF/cofilin isoforms evolved to fulfill specific requirements for actin filament dynamics in different cell types [13].
  • In cultured NIH3T3 and B16F1 cells, CAP1 is a highly abundant protein that colocalizes with cofilin-1 to dynamic regions of the cortical actin cytoskeleton [14].
  • Neural crest cells lacking n-cofilin do not polarize, and F-actin bundles or fibers are not detectable [12].
  • Here we show that in mouse the non-muscle-specific gene-n-cofilin-is essential for migration of neural crest cells as well as other cell types in the paraxial mesoderm [12].
  • Cofilin/ADF proteins are a ubiquitously expressed family of F-actin depolymerizing factors found in eukaryotic cells including plants [12].
 

Associations of Cfl1 with chemical compounds

  • In higher vertebrates, cells often express as many as three different ADF/cofilin genes and each of these proteins may be phosphorylated on serine 3, giving rise to up to six different species [15].
  • During in vitro myogenesis of mouse C2 cells, expression of the M-type cofilin was upregulated [16].
  • However, upon treatment with DMSO, cytoplasmic actin filaments were disrupted and intranuclear rod structures containing cofilin and actin were apparently larger and thicker in cells overexpressing cofilin than in normal cells [17].
  • The analogs of the unphosphorylated form (A3-cofilin) and the phosphorylated form (D3-cofilin) were prepared by converting Ser3, a regulatory phosphorylation site, to Ala or Asp [18].
  • Antibodies directed against cofilin labeled intranuclear actin rods induced in cells treated with dimethyl sulfoxide or exposed to heat shock and also labeled cytoplasmic actin rods induced in cells incubated in specific salt buffers [19].
 

Physical interactions of Cfl1

  • These data suggest that HSP20 may modulate actin cytoskeletal dynamics by competing with the actin depolymerizing protein cofilin for binding to the scaffolding protein 14-3-3 [20].

Analytical, diagnostic and therapeutic context of Cfl1

  • Northern blot and in situ hybridization analyses demonstrate that cofilin-1 is expressed in most cell types of embryos and adult mice [13].
  • Futhermore, this bank of antibodies was used to identify by Western blotting a putative member of the ADF/cofilin family in the sea slug, Aplysia californica [15].
  • From immunocross-reactivities and sequence alignments, the principal epitope in mammalian ADF and cofilin-1 recognized by an antibody raised against avian ADF was identified [15].
  • The mRNA encoding M-type cofilin, though it contains two variants that differ in the size of their 3'-non-coding sequences, was detected predominantly in heart, skeletal muscle, C2 myotubes, and testis by Northern blotting, while the mRNA for NM-type cofilin was seen in a variety of non-muscle tissues [16].
  • By means of immunoblotting combined with two-dimensional gel electrophoresis, we found that two cofilin variants, muscle type (M-type) and non-muscle type (NM-type), exist in mammals, while a single isoform exists in chickens [16].
