  • Function
    Vitronectin is a cell adhesion and spreading factor found in serum and tissues. Vitronectin interact with glycosaminoglycans and proteoglycans. Is recognized by certain members of the integrin family and serves as a cell-to-substrate adhesion molecule. Inhibitor of the membrane-damaging effect of the terminal cytolytic complement pathway.
    Somatomedin-B is a growth hormone-dependent serum factor with protease-inhibiting activity.
  • Tissue specificity
  • Sequence similarities
    Contains 4 hemopexin repeats.
    Contains 1 SMB (somatomedin-B) domain.
  • Domain
    The SMB domain mediates interaction with SERPINE1/PAI1. The heparin-binding domain mediates interaction with insulin.
  • Post-translational
    Sulfated on 2 tyrosine residues.
    N- and O-glycosylated.
    Phosphorylation on Thr-69 and Thr-76 favors cell adhesion and spreading.
    It has been suggested that the active SMB domain may be permitted considerable disulfide bond heterogeneity or variability, thus two alternate disulfide patterns based on 3D structures are described with 1 disulfide bond conserved in both.
    Phosphorylation sites are present in the extracellular medium.
  • Cellular localization
    Secreted, extracellular space.

  • This picture shows formalin-fixed paraffin embedded human skin stained with Vitronectin/S-Protein (1:100 - 30 minutes RT). The image was kindly supplied as part of the review submitted by Elizabeth Chlipala.

  • ICC/IF image of ab13413 stained MCF7 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab13413, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
