Target

  • Function
    Vimentins are class-III intermediate filaments found in various non-epithelial cells, especially mesenchymal cells. Vimentin is attached to the nucleus, endoplasmic reticulum, and mitochondria, either laterally or terminally.
    Involved with LARP6 in the stabilization of type I collagen mRNAs for CO1A1 and CO1A2.
  • Tissue specificity
    Highly expressed in fibroblasts, some expression in T- and B-lymphocytes, and little or no expression in Burkitt's lymphoma cell lines. Expressed in many hormone-independent mammary carcinoma cell lines.
  • Involvement in disease
    Cataract 30
  • Sequence similarities
    Belongs to the intermediate filament family.
  • Domain
    The central alpha-helical coiled-coil rod region mediates elementary homodimerization.
    The [IL]-x-C-x-x-[DE] motif is a proposed target motif for cysteine S-nitrosylation mediated by the iNOS-S100A8/A9 transnitrosylase complex.
  • Post-translational
    modifications
    Filament disassembly during mitosis is promoted by phosphorylation at Ser-55 as well as by nestin (By similarity). One of the most prominent phosphoproteins in various cells of mesenchymal origin. Phosphorylation is enhanced during cell division, at which time vimentin filaments are significantly reorganized. Phosphorylation by PKN1 inhibits the formation of filaments. Phosphorylated at Ser-56 by CDK5 during neutrophil secretion in the cytoplasm. Phosphorylated by STK33.
    O-glycosylated during cytokinesis at sites identical or close to phosphorylation sites, this interferes with the phosphorylation status.
    S-nitrosylation is induced by interferon-gamma and oxidatively-modified low-densitity lipoprotein (LDL(ox)) possibly implicating the iNOS-S100A8/9 transnitrosylase complex.
  • Cellular localization
    Cytoplasm.
  • Information by UniProt
  • Database links
  • Form
    Vimentin is found in connective tissue and in the cytoskeleton.

Tissue was fixed with paraformaldehyde, permeabilized with Triton-X and blocked with 7.5ug/ml 0.1 M glycine buffer for 30 minutes at room temperature. Samples were incubated with primary antibody (1/50) for 16 hours at 4°C. A Cy2®-conjugated Goat anti-rabbit IgG polyclonal (1/500) was used as the secondary antibody.

    Western Blot analysis using ab22651

  • ab22651 at 1µg/ml staining Vimentin (phospho S55) in human U251 cells by Immunocytochemistry/ Immunofluorescence.

  • Overlay histogram showing HeLa cells stained with ab22651 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab22651, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Mouse vimentin is Ser-55, which is Ser-56 in human vimentin. The antibody will recognize either (the immunogen is from mouse vimentin so the mouse phosphorylation site was chosen for the product name/description).

Thank you for your phone call. This antibody was tested positive with the following cell lines via WB: U251, NIH-3T3, and 3Y1-B. I would recommend using one of these as a positive control. It also tests positive with the phospho-Vimentin (Ser55) pepti...
