Application Abreviews Notes
WB Use a concentration of 0.3 - 1 µg/ml. Detects a band of approximately 38 kDa (predicted molecular weight: 38 kDa).


  • Function

    Calcium-sensitive protein which reversibly blocks the barbed ends of actin filaments but does not sever preformed actin filaments. May play an important role in macrophage function. May play a role in regulating cytoplasmic and/or nuclear structures through potential interactions with actin. May bind DNA.
  • Tissue specificity

    Macrophages and macrophage-like cells.
  • Sequence similarities

    Belongs to the villin/gelsolin family.
    Contains 3 gelsolin-like repeats.
  • Post-translational

    The N-terminus is blocked.
  • Cellular localization

    Cytoplasm. Nucleus. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
