  • FunctionPossible adhesion molecule with a role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. Could act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. Presents carbohydrate ligands to selectins.
  • Tissue specificitySelectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues.
  • Sequence similaritiesBelongs to the CD34 family.
  • Developmental stageOn early hematopoietic progenitor cells.
  • Post-translational
    Highly glycosylated.
    Phosphorylated on serine residues by PKC.
  • Cellular localizationMembrane.

  • Overlay histogram showing Jurkat cells stained with ab54208 (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 (ab54208, 1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H+L) (ab150113) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG ( 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

    Predicted band size : 41 kDa
    Observed band size : 35 kDa (why is the actual band size different from the predicted?)
