General description

Anti-Gelsolin Antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the GS-2C4 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Gelsolin operates in at least two variant forms encoded by a single gene and is located both intracellular (in cytosol and mitochondria) and extracellular (in blood plasma).

Immunogen

Human plasma gelsolin

Application

Anti-Gelsolin antibody, Mouse Monoclonal has been used in:
  • immunoblotting
  • immunofluorescence
  • immunohistochemistry
  • immunoprecipitation

Biochem/physiol Actions

Gelsolin, also known as Actin-depolymerizing factor (ADF), GSN, AGEL or Brevin, is a calcium-dependent actin-binding protein. Gelsolin acts as a main modulator of actin filament formation and disassembly and is involved in a variety of cellular mechanisms including apoptosis, signal transduction, transcriptional regulation and epigenetic processes. Plasma gelsolin differs in its sequence from the cytoplasmic variant in possessing a 25-amino acid N-terminal extension. The main function of the cytoplasmic gelsolin is to remodel the actin cytoskeleton. Plasma gelsolin′s main role is to scan for actin fibrils that are released by injured tissue into the bloodstream and to bind them in a scavenger mode preventing actin from increasing the blood viscosity. Gelsolin levels correlate with inflammation and several diseases and pathologies, including cancer, infection, cardiac injury, pulmonary diseases, Alzheimer′s disease and aging thus making it a potential biomarker of diagnostic and prognostic values.

Gelsolin is a Ca2+-sensitive 90-kDa protein which regulates actin filament length. A molecular variant of gelsolin is present in plasma as a 93-kDa protein. Functional studies have shown that gelsolin contains two actin-binding sites which are distinct in that after

Gelsolin, a multifunctional actin-modulating protein, has two actin-binding sites which may interact cooperatively. Native gelsolin requires micromolar Ca2+ for optimal binding of actin to both sites, and for expression of its actin filament-severing function. Recent work has shown that an
